I'm trying to upload my app to iTunes Connect with Xcode. I chose product > archive, choose my account, it compiles and when I try to upload it hand for a long time on:
Uploading Archive
Sending API usage to iTunes Connect...
Then it shows an error message:
I've restarted Xcode and the entire machine but still it keeps repeating itself.
What's wrong here?
This usually happens to me when the phone is connected while uploading the archive, and removing the phone so far has been solving the issue for me.
My solution was to install Application Loader. At first it seemed like it's stuck as well, but after about 10 minutes it started uploading.
I solved this issue.
There is a checkbox "include bitcode" at the bottom of the Summary screen (when you validate Archive) or Send XXX to Apple screen (when you upload to App Store) where the Organizer show the Binary and Entitlements together with Provisioning Profile. In XCode 7 it is checked by default. I unchecked it and re-run Validation - worked fine. As soon as checked the checkbox back on, it started failing with same error.
I have also unchecked the other checkbox on the same screen - symbolis upload.
Successfully uploaded the binary using the Organizr just now.
Here the solution that helped in Xcode 8, summary screen:
Still getting the same error despite "unchecking" bitcode and also archiving with the bitcode under Basic Profile turned off in the info.plist.
It would only work if I used Application Loader, like this:
First, export the application Archive from Xcode's Organizer window (it saves this into a directory on the Desktop).
Then, from Xcode:
Xcode > Open Developer Tool > Application Loader
My guess is that there is a bug somewhere either with iTunes Connect back end or xCode itself.
A couple of Xcode restart didn't resolve the issue but Application Loader solved it for the very first attempt. Also, Application Loader, is more descriptive for letting one know what's going on during the whole upload process. Plus simultaneous apps upload is possible via Application Loader.
I got this error when trying to upload an app to App Store Connect (01/20/2020). Restarting Xcode fixed the issue for me.
I've had the same issue.
Tried to upload the app with Transporter with no success.
Restarting of Mac and Xcode didn't help.
Solution was to logout from Xcode and log in back
Xcode -> Preferences -> Accounts -> Select your Apple ID and click on "-" below
To submit to App Store use Application Loader but after creating the "App-Specific" password as the following:
Log in to https://appleid.apple.com and enter your 2FA (TWO-FACTOR AUTHENTICATION) code.
Then in the Security section on the bottom right area, you'll see: APP-SPECIFIC PASSWORDS.
Generate Password... Click the link to create an app-specific password, Enter your password.
Copy the app-specific password. Enter the password into the Application Loader.
Choose the exported ipa to submit it.
For developers uploading apps with Xcode: simply change network and restart your Mac.
I solved this issue with Transporter, native Apple application. You can download it from AppStore.
https://apps.apple.com/ua/app/transporter/id1450874784?mt=12
This application has a much more information about uploading process and possible errors.
Install the "Transporter" app from the MacOS app store.
From Xcode's organizer, select your archive and press "Distribute App"
Select "Export" and proceed as usual.
Choose the exported .ipa file into the transporter and press "Deliver".
I was getting the same error. Application Loader didn't work. I couldn't open any Apple Developer/Forum webpages either to find an answer there. And iTunesConnect wouldn't let me log in. I thought the site was down and I couldn't even access the Apple Status pages.
My VPN was connecting outside the US. After turning off the VPN everything returned to normal. I have been letting the VPN connect to random places around the globe, probably should keep it in my area.
In my case, The build with the same number (e.g. Version 1.0(1.6)) was already been uploaded to AppStore. I found that after logging into itunes and checked the TESTFLIGHT BUILDS -> iOS and there I saw 1.6 (Processing)
Note: 1.0 is the version number and 1.6 is build number.

I have tried to upload my app to App Store (iTunes Connect) to test my app in TestFlight, but always appears the same error message. I don´t know what I´m doing wrong. It´s the third day I´m trying to upload my app.
Also read that this is a problem from Apple's servers, but every day is the same problem.
Please help me with this problem.
I have done it with Application Loader. First export the .ipa file, and then proccesed in Application Loader to visualize in iTunes Connect. Never works with Xcode.
You can try following solutions:
Use Application Loader to upload your app, as Xcode organizer can't upload file (rejects IPA) sometimes, without genuine reason and it's frequently occurring issue, with Xcode Organizer, that apple could not resolve permanently.
Solution to error code: 22421
Apple app upload server is not working properly (not in
connection or lost connection during file upload). Just wait and try
again later (may be after a day).
Fluctuation in your network
connection, during file upload.
You may not have added privacy
statements in your info.plist file.
Cocoa Keys: Here, is list of keys that you should consider to add in your info.plist file, if you have used that service in your application.
Nowadays, you may also face, this error code: 90186 (with app loader)
Outdated application loader can be reason of this error. Use latest Xcode tool and use application loader from Xcode Tool.
Incorrect/invalid provisioning profile, associated with your build. Ensure, your have used correct provisioning profile (A provisioning
profile with Distribution/Production mode is require. A Development mode provisioning profile won't allow your to upload app on store.)
You can find latest Application Loader Tool from latest Xcode Tool: Xcode ▶ Open Developer Tool ▶ Application Loader
try this
cd ~
mv .itmstransporter/ .old_itmstransporter/
"/Applications/Xcode.app/Contents/Applications/ApplicationLoader.app/Contents/itms/bin/iTMSTransporter"
I am using Xcode 7.2 and I am not able to submit my app due to a strange error: "iTunes Store operation failed". I've reset my certificates, reset my provisioning profiles, cleared out my keychain, and still no success. I've also gone to "Xcode -> Preferences -> Accounts" and deleted my account, and re-added my account. I then went into "View Details" and clicked "Download All". I've done research which all tell me to do the steps above, but I tried all these steps countless of times and I cannot seem to figure this out.
Any ideas?
Go to member center -> Choose iOS Provisioning Profiles (Distribution) -> edit - > add file "keychain access CertificateSigningRequest.certSigningRequest " from your device -->download provisioning profile certificate and add it to keychain access --> Quit Xcode and reopen hope it will work
Did you try unchecking the Include bitcode option before sending your app to Apple? I have been getting the same error quite frequently and what I notice is that it could do something with internet connectivity. When I submit my app from office with high speed connection, there is no problem at all. But from home where I have lot lower speed, I have to uncheck Include bitcode to successfully submit my app.
The only way I was able to upload my project to the app store was to use the Application Loader built into Xcode. I believe that this is a new bug with Xcode 7.2. Here is a detailed walkthrough of using Application Loader:
Trying to submit iOS and Apple Watch OS2 extension update from ios 9.0 to 9.1. I recently updated Xcode to version 7.1 and now I'm hitting this problem without changing anything else.
iTunes store operation failed you are not authorized to use this service
What I've tried:
Removed developer account from Xcode -> added developer account back into Xcode -> Still hit the error.
I tried Xcode -> Preferences -> Apple ID -> Download All to get my latest provisioning profiles up to date. Still get the error.
Deleted all old archives, cleaned project, archive again. Still get the error.
Increased build number and version number in both the project and in itunes connect. Still get the error.
Deleted derived data in the Library -> Developer folder and I still get the error.
Cleaned the project -> Archived the project again -> Unchecked "enable bitcode" and I still receive the error.
Code Signing Settings:
Watch Target -> Provisioning profile automatic code signing iOS Developer
Watch Target Extension -> Provisioning profile automatic code signing iOS Developer
iOS Target -> Provisioning profile automatic code signing iOS Developer
Still hit the error message with the provisioning profile settings.
Reinstalled Xcode 7.1 -> Still hit the error message.
I've also confirmed that all my developer and distribution provisioning profiles are valid and downloaded.
Observations:
One thing I've noticed is that when I archive the app and look in the Window -> Organizer I notice my iOS apps on the left side for my archives. This app I'm trying to submit has no name next to it. However, if I delete all old archives for this app the app name shows up again next to the app icon. Maybe a bug with Xcode but I have no clue.
Another thing I've noticed is I've been able to successfully submit iOS archives that have no WatchKit extension using Xcode 7.1. I'm not sure if the WatchKit extension could be the problem but it is a possibility.
Also when the archive is ready to be uploaded to iTunes Connect I notice a couple of things. First, the iOS App defaults to the active provisioning profile: "MyApp" Distribution profile. However, both the WatchKit app and app extensions automatically default to the XC* wildcard provisioning profile. I'm not sure if this whole problem could just be related to a provisioning profile error but it is possible.
iOS Target -> Build Phases -> Embed Watch Content is set as:
$(CONTENTS_FOLDER_PATH)/Watch
Application Loader Submission Attempt:
Tried and failed with the following error message:
ERROR ITMS-90171 "Invalid Bundle Structure - The Binary file 'MyApp.app/Watch/MyAppWatch.app/_WatchKitStub/WK' is not permitted. Your app can't contain stand alone executables or libraries other then the CFBundleExecutable of supported bundles. Refer to the Bundle Programming Guide..."
Again, I used this exact same project structure to submit the ios app and watchkit OS2 extension on Xcode 7.0 ios 9.0.x no problem. I think the error message is inaccurate unless I'm misconfiguring something but I imagine I would've hit the error back on Xcode 7.0
Any help on how to solve this would be awesome. I've found no help googling and reading other SO posts and I've been stuck on this for far too long. Thanks!
I met the same issue today and I think it is a bug of Xcode 7.1
Finally I managed to submit my app via Application Loader. There were warnings but it did work.
Here are the basic steps:
Archive
Export
Xcode menu --> Xcode --> Open Developer Tool --> Application Loader
Double click "Deliver Your App" and choose the file exported in step #2
click next and follow the instructions until the end
I found the solution by unchecking the Include bitcode option.
In mi case, it seems that updating to Xcode 7.1 removed some account information. So, after a few attempts to upload it from Xcode, I opened Application Loader, and it asked me to login. I logged in and finally could submit to the App Store from the Organizer. Hope it helps someone.
it is the enable bitcode on the bottom when you submit the upload. uncheck the box. for some reason it comes with 2 boxes checked by default on xcode 7.1
Set team in target-> General-> Team
Check and set appropriate provisioning profile in targets/project build settings.
Try with Xcode to upload build if find same issue.
Or
Try with application loader it will work.
In my case I think it should be a xcode 7.1 bug. I re-added my account, re-generated profile, rebuild the app (restart my mac) but none of them work! I got this error when I first validated the app.
Then I created a new profile and the validation passed. But the first time uploading the app xcode still showed that error. Unwilling to give up I clicked the upload button again and this time it succeeded!
I faced the same issue then I uploaded through Application Loader from XCODE menu and it showed so many error like missing icon for iPad etc .
So please try you app to load through Application Loader and see complete detail of errors you might have in your application.
I got it working through Application Loader after fixing these issues.
I am using Xcode 7.1.1. and it appears to be an issue with Xcode, because I successfully submitted the build via Application Loader. Now, I suspect that I added too many SDKs / adapters inside the code that may have caused issues with the app's delivery. But there's no way of knowing that for sure.
During upload my API Analysis to the App Store was skipped, because it was too large, but I doubt that may caused Xcode to upload the app to the App Store.
If Xcode fails to upload, try Application Loader.
Solved for Xcode 7.2 by revoking and recreating the cert:
Image of what to click here (sorry no embed reputation)
In XCode go into this menu:
XCode -> Preferences -> Accounts
When on the accounts tab, I selected my email in the Apple Id list (on the left).
Then on the right there is a list of of teams under Team Name, select the correct Team and click on View Details.
Finally, there's a list of Signing Identities, next to "iOS Distribution" click Reset.
I didn't have to restart XCode, I just immediately resubmitted to iTunes from Organizer with no problems.
Edit: Thanks #Dover8 for the info about possible effects.
https://developer.apple.com/library/mac/documentation/IDEs/Conceptual/AppDistributionGuide/MaintainingCertificates/MaintainingCertificates.html
Resetting Certificates Using Xcode
If Xcode detects an issue with a signing identity, it displays an
appropriate action in Accounts preferences. If Xcode displays a Create
button, the signing identity doesn’t exist in Member Center or on your
Mac. If Xcode displays a Reset button, the signing identity is not
usable on your Mac—for example, it is missing the private key. If you
click the Reset button, Xcode revokes and re-creates the corresponding
certificate.
Try to check your iOS Provisioning Profiles on
https://developer.apple.com/account/ios/profile/profileList.action
In my case one of profiles was marked as "Invalid" and after profile regeneration an error no longer appears
I got the same problem.
Tried to Upload To App Store.. 3-4 times.
Then I Hit the Validate... button and validation was success.
After that tried to upload again and it succeeded.
Then i cursed apple...
It seems to be related to the latest iTunesConnect update and "roles".
If I look at the "iTunesConnect Users" screen, we have three accounts,
(1) is "Admin, Legal", (2) is "Technical, Marketer", and (3) is "Technical Only".
Now when you click the email address to check the details and "roles" of #2 then only "Marketer" is checked, and only the marketer permissions are available.
For #3 the correct checkmark ( Technical ) is set, and also "Create Apps and Submit versions" is shown as an available "App feature".
It might be a work-around to change permissions to disable and re-enable "technical", or maybe give more permissions and make the person an Admin (temporary, of course).
Also - for the Jenkins users out there, you might have copied some certificates from the "login" keychain to the "system" keychain. Try removing them from the system-keychain ( I think that was this step which made my "Archive" not end up in 'not authorized ...' message and actually pass the verify again).
iTunes store operation failed
No eligible software found. Make sure this software is owned by your developer organization.
I get above error while validating app from xcode 6. I don't understand this error why it is coming. Can anyone help me to solve this error?
Thank you
I was able to upload by using Application Loader as suggested in iTunesConnect.
Archive your app with the distribution provisioning profile
Export the archive for distribution to somewhere you can find it again.
Download Application Loader 3.0 from iTunesConnect, if it isn't already installed.
Open Application Loader
In AppLoader, Log into the iTunesConnect account you want to release the app from
In AppLoader, Upload the archive
Not exactly painless, but it does allow you to build with an iTunes developer account and release from a different iTunesConnect ID.
I got this error while validating my app. The problem was that the developer account of which I was using the Provisioning Profile was different from that of the account that I was using to validate my app. In simple words: They were two different APPLE IDs.
You need to add the APPLE ID from which you are using the provisioning profile.
Follow the following steps to get rid of this error and add the APPLE ID:
After clicking on "Validate button" ---> Click on "View Accounts".
The following window will open. In this window click on + button as shown below.
A pop-over showing three option will be opened as shown below. Select "Add Apple ID".
A new window will be opened asking you to enter your Apple ID and password as shown below. Enter your Apple ID and password of the developer account from which you have used the provisioning profile. Then press "Add":
You will see a new Apple ID added in the list of the Apple IDs.
Close the Organizer window. ----> Archive the product again and Validate the app choosing the newly added Apple ID.
This happened to me because I had a different developer and itunesconnect accounts. Make sure you build app with your developer account and submit validation with your itunesconnect account. That worked for me.
As noted by a few others, I was able to resolve this problem by using the Application Loader rather than xCode to send the iPA file to app store. In my case, both xCode and Application loader were using the correct iTunesConnect account, but for some reason, xCode was failing on submitting this app. I could submit other apps without incident, which led me on a wild goose chase thinking the problem was app specific.
Steps to Resolution were:
Download to Application Loader from iTunesConnect Website (as of 2/18/15, it's under the Resources and Help button).
Install App Loader
From xCode, Build/Archive to create distribution package
From xCode Organizer, Export the package to a location
From App Loader, select the Exported Package IPA file and upload to App Store.
Glad to be past this one!
For me it helped to upload with the credentials of the account agent. A developer account didn´t work.
in my application this issue was coming due to of one error that's i uploaded wrong size image in ipad2x that's 152*152 by 144*144 , but some how i export the build and i uploaded it through application loader. application loader told me abt two warning after uploading the build that was not proper icon size image for ipad #2x and the other was 64 bit warning so i solved the icon problem and now i was abled to validate my app successfully with one warning still that's of 32 bit. if u had repeated the steps like you uploaded the build first from application builder than donot forgot to change build number.
Please check the application bundleID from itunesconnect & your project in Xcode.We will get this issue if our bundleID mismatch from itunesconnect & project..
I was getting same error. After some investigation, I identify the issue with bundleID. I changed the bundleId as per itunesconnect. App was validated & submitted successful in App Store.
I am facing an issue while submitting my app from Xcode to the App Store. I have done everything regarding my project, and its running fine on my iPhone and iPad. But when I submit my project I am facing a huge problem.
First after archive I have done the validate. Now my archive file in Organizer is showing status pass validation as well. So I believe I am at the final step of submitting the app.
I have clicked on distribute and selected submit app to app store.
After login I have selected provisioning files as well.
I am stuck here. You can see in the screenshot below. And I have never seen any
progress bar where I can see the submission progress or something like that.
Only screen I can see is:
Edited:
It was near about 1.30 hours. And internet connection is working. My ipa file is only 3.5 MB.
And last when I tried Application loader to upload the same I received the following screen as well for a long time in Authenticating with the iTunes Store... ..
What should I do now?
As I felt a serious issue on this. I believe this answer might be helpful.
After trying for around 10 to 12 hours to fix this issue and as everything else regarding my project and coding was fine enough, it became a headache for me. But after getting some valuable comments from some of the expert users of stack-overflow and after doing some more search on the internet, I have found some quality answers.
This answer helped me the most:
application loader stuck at the stage of "Authenticating with the iTunes Store"
If you are going to upload it through Application Loader and it gets stuck on "Authentication with the iTunes Store..."
or
You are going to upload it through XCode and it stucks on “Your application is being uploaded”
Then just keep your head cool and check this first method:
Check if your firewall protection is off. If not then turn it off. It maybe blocking you to connect your computer with iTunes
Store.
Try a different internet connection. The purpose for trying a different internet connection is that your current internet connection maybe blocking a required port for connection to Apple servers.
If the above steps doesn't help you then follow this second method:
Xcode needs java runtime for uploading your apps to the App Store.
enter 'java -version' in the terminal, java version should be 1.6 .If not then download
latest compatible java only from apple download center:
http://support.apple.com/kb/DL1572?viewlocale=en_US
If this still doesn't help then follow this third method:
This method enables the application loader to use the HTTP port instead of HTTPS.
Go to
Application Loader java folder :
/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/MacOS/itms/java/lib
Open net.properties file using any text editor application like text mate or sublime text
Change this particular line : #https.proxyPort=443 proxy port to
https.proxyPort=80
Save the file. And that's it !! You can easily upload your binary file to App
store now.
If the above methods still doesn't help then follow this fourth method: Regenerate your certificate
Goto iOS developer portal (https://developer.apple.com/membercenter).
Revoke current certificate which is used by your App for signing.
Remove current "iOS distribution provision profile" from Developer
portal.
Regenerate the iOS distribution certificate and add them in developer portal.
Regenerate "iOS distribution provision profile" for app store
distribution and download to mac.
Install it.
Try again using xcode/application loader to upload the build.
There is definitely a problem if your app stuck on "application stuck process". I suggest you to go with Application loader rather than Xcode itself as Application loader shows the activity status. You can clearly know in which step you stuck.
The most frequent issue faced is to stuck on the "Authentication with the iTunes Store..." step.
There are possible two work around which I followed and finally submitted my app to app store. You can try both. For me both worked at least once.
Method One : This method plays with proxy port to use http connection over https
Go to Application Loader java folder : /Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/MacOS/itms/java/lib
Open net.properties file with "sublime text" or "text mate"
Change "#https.proxyPort=443" proxy port to "https.proxyPort=80"
Save the file and reopen Application Loader and Try again.
Method Two : Regenerate your certificate and iOS distribution provision profile and Try to upload
Goto https://developer.apple.com/membercenter
Delete previous certificate referenced by your App for signing.
Revoke your distribution certificate and download it to your mac. And install it by double clicking it.
Delete current "iOS distribution provision profile" from Developer portal.
Regenerate "iOS distribution provision profile" for app store distribution and download to mac.
Install it by double clicking it.
Try again using application loader to upload the build.
Edit: I again got this problem while uploading new build. Both of above methods were followed but was stucking in "Authentication..". Restarted the mac book and it worked. When you restart, the previous itunesconnect connection (which you might have opened in browser prior to submit your app) are reset which allows restarted mac to easily authenticate iTunes Connect. Yesterday (jan 26, 2014) the iTunesConnect authentication step proceeded within 2 mins. Hope this helps someone who is loosing patience while stuck on authentication step.
Edit 2: Before deleting distribution Certificate, try only regenerating "iOS Distribution Provision Profile". It worked for me else you can redo as above.
I Hope this helps. All the best.
I tried all the steps from Rajan's solution; none worked. However, this threads on apple dev forum (https://forums.developer.apple.com/thread/76803) gave me the solution in my case :
Try this, it fixed it for me. Open Terminal and run:
cd ~
mv .itmstransporter/ .old_itmstransporter/
"/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter"
iTMSTransporter will then update itself, then you can try uploading in XCode again.
For me, just logging out from ituneconnect website and developer.apple.com does work.And just using xcode to upload. No need to restart
I got this issue today. But finally I found it's caused by my wrong settings.
In 'Build settings' of the target, change settings "Code Signing Identity -> Release" to your production certificate, and "Provisioning Profile -> Release" to your distribution provisioning file.
Then archive and distribute it again.
You can try to cancel the upload and retry. If that does not work you may want to try the Application Loader from Apple. It essentially does the same thing, but does not resign the binary. You can download the application loader from itunes connect. See https://itunesconnect.apple.com/docs/UsingApplicationLoader.pdf (Getting Started, Page 9)
I had the same issue.
I cancelled and ran a validation check. It turned out I had written a URL Scheme incorrectly.
Xcode did not gave any errors when uploading and simply got stuck but validating gave the error.
So, try validation first. Hope this helps someone.
try this on terminal
cd ~
mv .itmstransporter/ .old_itmstransporter/
"/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter"
worked for me after hours of researching
This is Happened Due to the iTMSTransporter
Try this, it fixed it for me. Open Terminal and run:
Use these commands one by one on the terminal. Hope it will help you
cd ~
mv .itmstransporter/ .old_itmstransporter/
"/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter"
iTMSTransporter will then update itself, then you can try uploading in XCode again.
I met this issues many times, I tried all steps but it still not working (home network) and try other network work fine (company network).
I fixed this problem by update latest Java SE from 1.6 to 1.7 and it work like a charm
To be honest, this may not be an answer but it really worked for me.
I launched Application Loader and started submitting. While sumbitting was going on,
I launched Organiser and select Distribution over archiver in Xcode as well and started uploading concurrent.
They worked together and 2nd one completed the submission.
Just my experience.
For me the issue was that I've changed my Dev. Account at some point of time and Application Loader itself was not authorized anymore. You have to manually to go it (Xcode -> Open Developer Tools -> Application Loader) and fill in your account details
I had the same issue. I as able to fix it by:
Remove/delete all distribution certificates and provisioning profiles from my machine.
Revoke distribution certificates and delete distribution provisioning profiles from Member Centre at developer.apple.com
Create a new Distribution certificated by generating a new certificate signing request from keychain access
Create a new provisioning profile for app store distribution
Download newly created certificate and add it to keychain access
Download newly created provisioning profile and add it to xcode. OR sync from Xcode from account settings.
Try to upload again.
This is some silly issue that Apple needs to fix asap. I wasted 2 days from something as silly as this.
I had the same issue. Trying all these answers may work sometimes, but usually it takes much time and may not work at the end like in my case.
I figured out a solution which will probably work for all.
Create your .ipa file by: Product -> Arcive -> Disribute(Save for Enterprise or ...) -> Next and save .ipa at target
Xcode -> Open Developer Tool -> Application Loader -> Deliver your app -> Pick your .ipa file
Withing few minutes your app will submit to iTunes. Good luck
All i did was duplicate my Application Loader.app in /Applications and ran both Application loaders at the same time.
I had the same issue after updating Xcode5 to Xcode6. After hours of craziness, the one and only thing that helped me was to delete my account in Xcode preferences and add my account again.
Last week I had the same issue after update to Xcode7, this helped me again...
If you are running inside a virtual machine (e.g. VMWare or VirtualBox), try setting the network adapter mode from the default NAT to Bridged.
This worked for me:
Logout from iTunes portal in all the browsers.
Restart your Mac machine.
Open Application Loader
Click on your Apple Login in the Top Right corner of the Application Loader Window.
Clicking Next will succeed your authentication process.
Now, do your process as usual by clicking upon the "Deliver Your App" and following the procedure beyond that.
My problem was I forgot to change the Bundle Identifier in info settings for the target. Hope it help someone.
I had similar issue while uploading iOS apps through application loader.Then once after i opened iTunes parallel all of the sudden uploading apps was faster.Not sure if iTunes has any dependency with application loader.
None of the answers worked for me and my upload was hanging for days without any error. (my build was generated using Expo). Here's what I did to make this work:
In the apple's guideline, it says one way to upload the build is to use the Transporter.
Using the Transporter, it was able to detect and output the error.
It turns out the root cause for me was the XCode version was 9 but it has to be 10.
I hope this helps others who are struggling on this issue.
