In Xcode 6.3, I got this error when trying to run an iOS project written in Swift on a real device.
App installation failed
could not write to the device.
I tried to clean the project and run again, but the same error occurs.
How can I fix this error?
Deleting the app on the device and running the project again works for me.
I did a Clean and installed my app successfully.
Product->Clean(Shift-Cmd-K)
I turned off the device and turned it on again after which I did not get such error.
OK, few things you should consider that could guide us to the problem, please check and post the answers:
is your project using capabilities? are they set correctly (should be all green)
did you try with a different project (something really simple)?
are you able to install apps from the App Store?
did you check the amount of free space left in the device?
if not, another suggestion will be using exception breakpoint, there is someone that posted an explanation how to setup it, do it and post the logs
App installation failed
I hope it helps you
Got this problem twice in one week on complete different devices.
One device had no more storage left, after deleting some apps the project installed perfectly.
The other device was fixed after rebooting the device
If you are using a free developer account you may need to uninstall some other apps you have signed.
For me it was the provisioning profile - I used distribution instead of development
My issue was an embedded framework.
Go to "Build Phases" -> "Embed Frameworks" -> Check "Copy only when installing", and it got rid of the issue for me.
For me the following did not work on iOS 11 beta 10, XCode 9 beta 6:
Restart the device
Deleting the app from the device
No symlinks were in the project
There was plenty of storage available
Deleted Derived Data and voilá, it worked again
in my project this problem happened because there was a folder with symbolic link. I removed that folder and it worked properly.
This error has many potential root causes, as can be seen by the large variety of suggested answers. The best approach to troubleshooting app installation issues like this one is usually to inspect the console of the iOS device itself, as that'll often provide much more specific error messages. In Xcode open the 'Devices and Simulators' window and take a peek at the logs of the device where your app is being installed.
In my case, the "Could not write to the device" error was being caused by this:
Feb 27 10:54:58 iPhone-7-110 installd(MobileSystemServices)[46] : 0x16f92f000 -[MIBundle _validateWithError:]: 38: Failed to load Info.plist from bundle at path /private/var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.ebmR6U/extracted/SampleApp.app/Frameworks/SomeFramework.framework
Which clearly hints at what's actually going on. I had forgotten to set an Info.plist file for my dynamic framework target (used by the app).
I had a symlink in my project to a file outside of the project. When I deleted this symlink the install worked fine.
I was having the same error, i just deleted the project and fixed!
Go to Window -> Project and right click, and remove from projects!
In the case of your device have an app with the same bundle identifier, Xcode will throw this error.
Try to delete potential app with the same bundle identifier.
Check your provision profile, maybe you are using the app store provision profile like me. I had to change the app store provision profile to development, now it's working.
Tried all of the above answers: Deleting the app, clearing storage space, cleaning the project...
What finally worked was bumping the build number in info.plist (General > Build)
For anyone still facing this Issue:
There are so many reasons and this is one of them as it happened to me.
I've faced the same problem and I was connected wirelessly and If you are trying to install the application in wireless connecting mode (connected through same network), this might probably because of poor internet connection. Check your internet connection and try again, it works fine...
Get rid of embedded libraries, dont' just throw it in there make sure it is embedded indeed.
If you use your iPhone for debug, maybe, because your iPhone's storage space is less than your debug App.
Clean your iPhone --- Real machine
Clean your Mac --- Simulator
This looks like another time waster courtesy of Apple's amazingly high class development team. On iOS11 Xcode9 (pick your beta, any one works) this will happen randomly. Appears to be more frequent if you dare to switch apps while compiling. Just build again and stare at xcode - it'll work the second time without fail in my experience.
Apparently this message can also appear if the system clock of device where the app is being installed is too far away from the current time.
I was doing some tests with date formatters by changing my iPhone's system clock and eventually forgot to reset it to the current time. Afterwards it always displayed the same message ("could not write to the device.") whenever I attempted to run the app. Simply resetting the clock in Settings fixed the issue.
Nothing helped me. I followed the below steps,
Clean derived data folder
Quit Xcode and disconnect device
Restart Macbook
Restart Device
Open Xcode
Clean and run the project
Finally I got it working!!
I am facing same issue then solved out follow this step and now its working.
Deleting the app from the device
Try to install another application
Remove derived data in X-code.
Restart X-Code then clean and build the project then run.
It's still not working then
Remove un-used application
Restart the device and check the Available and capacity in settings
Again app run in device
I hope its worked, enjoy it.
My problem was I had initially installed the app using a different set of developer credentials on the device. Deleting the app from the device fixed it.
Maybe it can be due to the following error App installation failed. No code signature found. In my case after a project clean the description of the error switched to "No code signature found".
In my case I created two frameworks but they had the same bundle identifier.
This caused the installation to fail, so double check the frameworks bundle identifiers and make sure that each of them have a unique bundle identifier.
Environment: Xcode 10
sometime this error occurs due to wrong certificate.Please make sure your certificate.
Also this the error shown if your machine running Xcode is low on space.
Once I had to load an App Container for debugging purposes into an iPad, said operation failed because the container was too big (18 GB) for this device (16 GB minus the OS), so that I desisted the task and completly forgot about it, leaving the failed installation in the device. Later, when trying to install a different application this error appeared, once I got rid of the failed app installation, everything got back to normal.
Basically, your Ipad might be low in storage.
One reason this can happen is if your app bundle contains broken symlinks.
We have been trying to submit an app to the iTunes store using Application Loader for three days and keep getting stuck at the "Authenticating with the iTunes store" step.
We have read many forums (including stackoverflow) and tried what was suggested:
making a new provisioning profile
using different or multiple versions of Application Loader
changing proxy settings
rebooting the Mac
uploading at a different time of the day, etc.
We have even left it running overnight and have not had success with getting past this step. Unfortunately, no feedback is given about what the issue may be, and we have not gotten any error messages. We have submitted multiple apps without any difficulty in the past but are completely stuck this time!
How were you able to solve it?
This only started happening to me today (May 2017) and no answers in this thread solved my issue. The resolution for me was from here;
https://forums.developer.apple.com/thread/76803
Open Terminal. Change to home directory,
cd ~
Move the current transporter directory,
mv .itmstransporter/ .old_itmstransporter/
Invoke the following file to let Transporter update itself.
"/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter"
Wait till it updates, then open Xcode and attempt upload.
You have to agree to a new sign up in Application Loader. Select "Application Loader" under the "Xcode -> Open Developer Tool" menu (the first menu to the right of the Apple in the menu bar). Once you open Application Loader there will be a prompt to agree to new terms and then to login again into your iTunes account. After this any upload method will work.
Just wait. In a few minutes all will be ok.
Dec 10th 2019, Xcode Version 11.2.1, MacOS X 10.15.1
I was facing exactly same issue yesterday and I thought it might be network issues, at least it looks like so. But this morning I had tried couple different networks and several VPN connections, none of them is working!
The highest voted answer here asks me to reset a cache folder named .itmstransporter under my home dir, the run a program iTMSTransporter under a specific folder, but I can't find both of them.
But soon I figured that it is the cache folder for the people who uses the legacy uploader program: Application Loader, which is deprecated by Apple and can be no longer found in Xcode 11. Then I found that the latest Xcode has located iTMSTransporter here:
/Applications/Xcode.app/Contents/SharedFrameworks/ContentDeliveryServices.framework/itms/bin/iTMSTransporter
And its cache folder is here:
/Users/your_user_name/Library/Caches/com.apple.amp.itmstransporter/
I removed my existed cache folder, and run iTMSTransporter without any parameter, it soon started to output logs and download a bunch of files, and finished in 2 or 3 minutes. Then I tried again to upload my ipa file, it works!!!
CONCLUTION:
Either the old Application Loader, or the latest Xcode, uses a Java program iTMSTransporter to process the ipa file uploading.
To function correctly, iTMSTransporter requires a set of jar files downloaded from Internet and cached in your local folder.
If your cache is somehow broken, or doesn't exist at all, directly invoking iTMSTransporter with functional parameters such as --upload-app in our case, iTMSTransporter DOES NOT WARN YOU, NOR FIX CACHE BY ITSELF, it just gets stuck there, SAYS NOTHING AT ALL! (Whoever wrote this iTMSTransporter, you seriously need to improve your programming sense).
Invoking iTMSTransporter without any parameter fixes the cache.
A functional cache is about 65MB, at Dec 10th 2019 with Xcode Version 11.2.1 (11B500)
I was stuck at "Authenticating with the iTunes Store" today. I had used the same version and build number as a previous submission. After I updated the build number, the upload went fine. I don't know if it's related, or if it was a coincidence.
I had the same issue for months, I just removed hotspot shield and private tunnel applications from my computer and tried to upload my app and everything worked just fine. so I suggest if you have installed any VPN application on your computer, remove the application and then try uploading your app from either application loader or xcode's organizer.
Try answer mentioned in this Reference Link, it really worked for me and for others as well.
Mentioning answer here as well.
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 or via application loader.
There is no magic fix. Itunes is just working bad. Lately is having more and more issues and it takes more and more to update and send an ipa to the store.
I had this issue with AppLoader and Xcode organiser too and after trying multiple times it just went through.
Changing network connection helped.
Turned off wifi on my phone
Enabled 3G
Created HotSpot
Connected my mac to the hotspot and got through the authetication issue
In my case, I hadn't agreed to the newest Developer Agreement. Just run Application Loader once, click on [Accept] to agree, then quit the Application Loader and the Upload to App Store should work fine.
Following worked for me.
Open another instance of Application Loader.
( Select "Application Loader" under the "Xcode -> Open Developer Tool" menu)
"Agree" to the terms.
After completing Step 2. First instance of Application Loader proceeded to the next step and build got submitted.
I have also encounter the same issue. One possible solution is to go to Xcode -> Preferences -> Accounts and from the left menu select on App ID then click on the View Details and tap on the refresh button. while reloading you will get following error
The selected team's agent, 'ADMIN NAME' must agree to the latest
Program License Agreement.
If you will not get above error, Following solution will not work.
It means that you need to login into the developer account using Admin login and accept that latest agreement.
Then you will be able to upload binary on the app store.
The updated answer for Xcode 11.x.x and Transporter application, open terminal:
rm -rf ~/.itmstransporter/
"/Applications/Transporter.app/Contents/itms/bin/iTMSTransporter"
Wait a while
Problem solved!
I'm running MacOS Mojave 10.14.6, Xcode 11.3.1 and Transporter 1.1.1, and always got stuck at the Authentication with App Store stage, no matter how long I wait, I tried uploading using Xcode, using xcrun altool, Transporter, nada.
Finally I got it working by exporting the ipa file to a new Macbook (10.15.3, Xcode 11.3.1, Transporter 1.1.1), and used the Transporter app to upload it there.
The key difference is the Transporter tool on my new Macbook asked for a 6-digit code as authentication while the old Macbook did not, I suspect the authentication token on my old device expired but the system didn't ask for a new one when trying to upload the app. I had 2-FA enabled.
So I think forcing a manual re-authentication when you upload the app is the answer, the only other difference is the MacOS version, but I didn't test if it'll make a difference.
I solved the problem by removing ~/Library/Caches/com.apple.amp.itmstransporter.
For safety, renaming will be better,
cd ~/Library/Caches
mv com.apple.amp.itmstransporter com.apple.amp.itmstransporter.old
Then, xcrun altool uploaded my ipa successfully.
By the way, I'm using Xcode 11.x & 12.2, macOS Catalina.
In 2020 Dec, the fix did finally worked for me was restarting my mac.
Today I ran into this issue, on Xcode 11.2.1 I solved it by going to Xcode -> Preferences -> Accounts -> Tapped on the '-' next to my Apple ID, then signed in again. This fixed it for me!
In April 21, 2021, I followed #DawnSong's answer, outlined in the image below but I also restarted my Mac and voila it worked.
Spec
Xcode 12.4
macOS Big Sur 11.2.3
You may try to relogin your ITC account via Application Loader.
Just try a different Internet connection. I tried all the solutions above but none worked. However, when I tried using my cellular connection (instead of my DSL connection that stands behind a firewall), it worked immediately.
It might be a network issue. 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.
All i did was duplicate my Application Loader.app in /Applications and
ran both Application loaders at the same time.
this solution is out there, it used to work for me, but today not even that! what I did and worked is that (2 instances) + uploading with XCode (organizer). Had to try a couple of times and it worked.
hope this helps someone, this bug has been there for quite a lot of time now() an apple doesn't seem to care too much
Another reason could be that you have changed the machine from which you're submitting the app. Or the user account on the machine. The new machine may lack the private key and/or certificate for the App Store. Although a certificate with the correct name is displayed in Xcode.
In this case, go to https://developer.apple.com -> certificates, use the plus sign (+) to add a new certificate (distribution), and follow the steps to request a certificate for the private key on your current machine. After installing the certificate, authentication may work.
For me I tried almost all the suggestions given above but the problem still reoccurred after the first success in uploading to App store. Until I found this website. In summary, do the following
Open terminal
Run this command:
rm -rf ~/.itmstransporter/
“/Applications/Xcode.app/Contents/Applications/Application
Loader.app/Contents/itms/bin/iTMSTransporter”
Note: this command(which is different from others above) will delete your ITMSTansporter folder and create a new one and ensure that xcode is quitted before running this command.
3. Start Xcode and all should be well.
Using Xcode 12.3 Distribute App and xcodebuild both got stuck today at this point.
I finally was able to solve this. Peeking around my system I found 3 versions of iTMSTransporter.
Printing the version of each using ./iTMSTransporter -version gives the following results:
/Applications/Transporter.app/Contents/itms/bin/ has version 2.0.0
/Applications/Xcode.app/Contents/SharedFrameworks/ContentDeliveryServices.framework/Versions/A/itms/bin/ has version 2.1.0
/usr/local/itms/bin/ has version version 1.9.3
So it looks that old version in /usr/local/itms was used by Xcode. After deleting /usr/local/itms I was able to upload my binary within Xcode 12.2 and using the xcodebuild command line tool.
Check your firewall
Network settings - (Check with network admin, usually they have blocked apple services unknowingly)
Check your system data/time.
I had same sort of issue, I resolved it by getting direct access to internet.
Also check Application Loader logs to see at which point it gets stuck.
I think I followed all the approaches given, but none worked for me.
My own approach that seems to work for me is to go thru the initial steps to upload a binary, then, after selecting the binary, do NOT click Send; instead close the window, and in the new window that will appear, start anew: hopefully it will go thru.
Found the solution:
I was uploading the build, Every activity went well except “Authenticating with the iTunes store”.
I disconnected my LAN cable and Connected my MAC with my mobile hotspot. and authentication problem was solved. If you have a limited internet plan then as soon as you pass authentication stage, again connect your LAN so that it will upload the app from you LAN cable's internet connection.
my upload failed each time when I uncheck the "include bitcode" option when uploading. So I checked the "include bitcode" option and upload went well.
Check your Firewall, If it is "On" then just Off it, then try
I know there's a lot of posts with the same that problem. I just spent at least 2 hours to read them and I tried everything I saw in the responses but it still doesn't work. I don't know what to do anymore. Can someone help me?
I use Xcode 4.2.1
This problem occurs regularly for me, and the solution was always to kill the process named SimulatorBridge.
And to simplify the solution you can add a custom 'behavior' in Xcode to do the task by following these steps:
Make a shell script file with this command:
#!/bin/sh
killall SimulatorBridge
Save it in ~/Library/Developer/Xcode/UserData/Behaviors/ as KillSimulatorBridge.sh.
Open Xcode > Preferences > Behaviors, and add a new behavior to run the shell script:
Now, you can run this behavior whenever Xcode hangs while trying to attach to your app, and you can even have a keyboard shortcut to run it.
Hope this helps someone.
It can also happen when a different user account has the simulator running on the same computer. In that case, close the simulator on the other user's account and try again.
Restart your computer.
The simulator sometimes gets stuck and this is the only way I know to reset it. The same thing can happen to the device as well and you just have to switch it off and on again.
If that doesn't work, you may have to reinstall the SDK.
