This post relates to a rapidly changing event.
I've tried all the other questions and searched everything on this that I could already, a lot of the other questions involved existing apps that were being updated or people with developer accounts but this is like my second time using Xcode and it has worked before.
This just happened out of nowhere. I keep getting these two errors and it allows me to run simulators but not build onto my iPhone:
Automatic signing is unable to resolve an issue with the "LearningSpriteKit" target's entitlements.
Automatic signing can't add the application-identifier and keychain-access-groups entitlements to your provisioning profile. Switch to manual signing and resolve the issue by downloading a matching provisioning profile from the developer website. Alternatively, to continue using automatic signing, remove these entitlements from your entitlements file and their associated functionality from your code.
Provisioning profile "iOS Team Provisioning Profile: #####.LearningSpriteKit" doesn't include the application-identifier and keychain-access-groups entitlements.
This issue is related to Bug 1534145. SSL.com: P-384 curve / ecdsa-with-SHA256 certificates.
A representative from Apple estimated 558,000 certificates to become invalidated: Bug 1533655. DigiCert: Apple: Non-compliant Serial Numbers
GoDaddy, Google, Apple and Facebook (that would explain why Facebook was glitchy today) are affected.
They are working on resolving the issue right now.
That would explain our problems, folks!
Update: The issue has been resolved. Try to refresh your projects.
Workaround: change Bundle Identifier and/or Version.
I restored a profile from Time Machine when this was working and upon launch, Xcode immediately deletes and replaces it with a new one. The key difference seems to be the old profile has the get-task-allow entitlement while the new one has NO entitlements. This is definitely broken at Apple's end.
Edit: The entitlements should also include a keychain access group, but again, no entitlements at all. Should look like:
It seems Apple broke the automatic signing system.
I was playing around with a few projects and Xcode just fetches the incorrect profile.
This worked for me:
Turn off "Automatically manage signing" in project target
Go to ~/Library/MobileDevice/Provisioning Profiles
Remove previously downloaded profiles
Turn on "Automatically manage signing" again
EDIT
As per latest update Apple successfully resolved Automatically Code
Sign with Free Account issue.
I tried it and I can confirm its resolved.
Please try at your end.
Update
Tested with Latest XCode 10.2 and it's working fine + they improved
performance of overall Xcode & codesign feature.
I am also facing the same issue while I am creating a new Profile from Xcode and if I go to other projects and check over there also I am facing the same issue as below.
Due to this issue, none of my projects can build with the old profile and certificate.
The strange issue, so I checked a newly created Profile and compared with the old one, and I found that App ID is unknown as well as there were no Entitlement details in the newly created profile.
Check the below screenshots of the old and new profile comparison:
Old Profile:
New Profile:
So it means it's not able to set App Id and Entitlements in the new profile. So the end result does not work all old profiles and giving the same error in all projects.
Issue Workaround:
Step1: Go to Provisioning Profile folder (path: ~Library ▸ MobileDevice ▸ Provisioning Profiles).
Or use a shortcut to jump directly into this folder like CMD + Shift + G and enter ~/Library/MobileDevice/Provisioning Profiles it will redirect your finder directly on the Provisioning Profiles folder.
Step2: Sort the files inside that folder by Date Modified.
Step3: Check profile with Unknown App Id and delete all unknown profiles.
Step4: Come back on Xcode and check all old projects will work as expected.
Note: Make sure none of your project open while doing above changes.
Otherwise, it will create a new profile with Unknown App Id.
I hope this will help and Apple will solve this bug soon!
UPDATE: This solution still works as on 2019/Mar/20 7:00 UTC+0
SOLUTION: no Xcode reinstallation is required. I used a brand new free AppleId, but later checked with my old AppleID and it also works.
In Xcode, under the General tab, untick the Automatically manage signing option
Close Xcode.
Erase old profiles in ~/Library/MobileDevice/Provisioning Profiles:
cd ~/Library/MobileDevice/Provisioning\ Profiles
rm -rf *
On MacOS, run Launchpad → Other → Keychain Access and remove all certificates related to iPhone development, like the following four on the picture:
Apple Worldwide Developer Relations Certification Authority
Developer ID Certification Authority
iPhone Developer: your_name_or_email
Uninstall the old app on iPhone. Restart both iPhone and Mac
Open Xcode and change the Bundle Identifier of your app, at least one character (later you may revert this change)
Enable the Automatically manage signing option in Xcode.
After this you should be able to run and debug your app on your device.
If you have a “iPhone has denied the launch request” problem, the solution is in an answer to Stack Overflow question iOS 12 iPad Denied Launch Request - Xcode.
In short, you need in Xcode to go to menu Product → Scheme → Edit Scheme... and select Executable: ask on launch.
This issue has been resolved, BUT some people still have a problem with it. If you're one of them, try the following:
1. In the General tab of target settings - uncheck the Automatically manage signing option
2. Close Xcode (fully, not just your project)
3. Erase .mobileprovision files under ~/Library/MobileDevice/Provisioning Profiles/
4. In Keychain Access, delete the following:
iPhone Developer: youremail#email.com
Developer ID Certification Authority
Apple Worldwide Developer Relations Certification Authority 3.
5. Delete the app on your iOS devices
6. Restart your Mac and iOS devices
7. Open Xcode again
8. Change the Bundle Identifier (even if it's a single character, you'd change it back to the original after you get it going)
9. Check the Automatically manage signing option
10. Use USB to connect your iPhone/iPad.
11. Make sure you trust your certificate on your iOS devices
This should do work for you.
It seems that this problem has been resolved now and the personal accounts can resign their apps automatically again.
Regarding to #Paul answer, it is not related to uninstalling Xcode. It is fixed from the server side.
The only thing that is required is removing Apple Developer Certificate (for the personal account) from your keychain, so that Xcode retries to generate and download a new one.
Here is the solution:
Let Xcode be open.
Select your developer account and let the error appear again.
Go to the keychain app
4.a) Goto certificate section
4.b) Remove All (valid and invalids) certificates (I have three valid and many invalid!)
After removing the last certificate, macOS will recreate a new certificate for the active developer account automatically.
Run your app in your iDevice. You need to enter your system password to add newly created certificate into the Keychain.
If in the second run it says
Your iPhone has denied the launch request
Just go to:
Product → Scheme → *edit scheme: uncheck "Debug executable"
I hope it solves your problem.
I got it to work by doing the following steps:
Go to Xcode
Preferences
Accounts
Manage certificates
Plus sign
iOS Development
Done
Download manual Profiles
Close
Go to your target
Change development team to none
Change development team to your previous team
It should work.
I am finally able to deploy to our iOS devices again. Here are the steps I took to make it work.
First, I followed all 10 steps in Zameer's answer here. I have copied them below:
Open your project in XCode.
Select your project from the project navigator and then select your target from the column.
Click on the General tab and under the Signing section, make sure "Automatically manage signing" is enabled.
Click on the Capabilities tab and turn On both the "App Groups" and "Keychain Sharing" settings. This might raise an
"Automatic signing failed" popup error, just click cancel to make it go away.
This should generate a entitlements file for you named nameProject.entitlements in the project folder of your project navigator.
Move this entitlements file outside of the folder, just below your project file.
Select your target again and return to the Capabilities tab to turn Off both the "App Groups" and "Keychain Sharing"
settings. This again might raise an "Automatic signing failed" popup
error, just click cancel to make it go away.
Now select your project above the target and go to Building Settings tab.
Scroll down to the Code Signing Identity setting under the Signing header and select iOS Developer from each drop down.
Under the above Signing header, double click the text field beside the Code Signing Entitlements and enter the name of your
entitlements file, nameProject.entitlements.
After completing those 10 steps, the 2 red entitlement error messages in XCode went away and I was able to build and deploy the XCode test app to the iPhone and run it.
Although that XCode test app could build and deploy, I develop on a PC using Xamarin and I was unable to deploy my Xamarin.iOS application to my iOS devices and kept getting an error in Visual Studio: the executable was signed with invalid entitlements. I did the following things and now I can deploy my Xamarin app and run it on my iOS devices:
I deleted the provisioning profile from the Mac in the ~/Library/MobileDevice/Provisioning Profiles directory. XCode immediately generated a new provisioining profile (I'm not sure if this step was necessary but I'm just writing it because that's what I did).
I changed my Xamarin.iOS.csproj file and removed Entitlements.plist from the CodesignEntitlements element so it now just looks like <CodesignEntitlements></CodesignEntitlements>. Visual Studio automatically added two elements to the same propertygroup in the project which are probably not necessary but I thought I'd mention: <CodesignExtraArgs /> and <CodesignResourceRules />.
Maybe forum post [iOS 12 SDK] - deadline March 2019 - Legacy Mode might help.
It talks about Apple refusing to build iOS applications under SDK 12 as of March 2019 (OP from Dec 2018).
I've not yet tried this, but it may be linked to the issue. I have a free developer account and am also experiencing this bug.
Here's a screenshot in case the link changes (screenshot 1 below).
This is the link from the first screenshot (screenshot 2 below)

There is one other potential source of this error. If you do not have a valid signed development certificate setup within your Xcode environment it will throw similar errors as posted by the OP.
You can check out your development certificates status following the Apple link here.
For macOS Big Sur Beta
Archive in Xcode 11
Upload with Xcode 12 beta organizer (Window -> Organizer)
For me, it finally works again. Either they just fixed it or any of my other steps helped:
Uninstall Xcode and all related files (using AppCleaner)
Install Xcode via the App Store
Change the Bundle Identifier of the App
Remove all "iOS Developer" Keys from Keychain
Here is a temporary workaround:
Change Bundle Identifier: Target → General → Identity → Bundle Identifier (set this to a different value than it is right now)
Change Version: Target → General → Identity → Version
Disable debug executable: Product → Scheme → Edit Scheme (uncheck the box that says "debug executable")
Delete Provisioning Profiles: ~/Library/MobileDevice/Provisioning Profiles delete everything in this folder.
You now should be able to build and run projects on simulators and devices.
I am trying to test my unity game on different iOS device using Xcode 7.3.1. Previously, I connect my iPhone 6 on mac and test the game successfully with free apple account(that has limited privilege).
Now I want to test that game on different device and later want to upload to app store. So I asked my client for apple id that has role "agent". I add apple id on Xcode and try to run the project with iPhone 6 connected. I got the error message saying-
"Your account already has a valid iOS Distribution certificate"
"You have a valid iOS Distribution certificate in the Member Center, but it is not installed locally. If your signing identity is installed on another Mac, you can export a developer profile on that Mac and import it on this Mac. You can also reset your current certificate."
Then I click on reset button to reset current certificate. And try to run the project again. Again I got the error message saying-
Unable to fix signing issue.
Xcode failed to resolve the issue. Check your code signing settings; ensure you have a matching signing certificate and provisioning profile installed; and try again.
I restarted Xcode many times but got the same error. Screenshot of my account details looks like below .
enter image description here
It is not enough, to login and download Developer profiles only.
You need that Certificate physically and signed in your mac as well.
Ak your client to export Signing identities and Provisioning Profiles.
This you will be able to import to you Xcode and Keychain in one step.
This process will help you handle private keys as well, as they are necessary if signing App using Developer/Distribution Certificate.
1) Your client has to export Identities and profiles:
2) He/She can send you them by e-mail:
3) You can import them all in one.
https://developer.apple.com/library/ios/recipes/xcode_help-accounts_preferences/articles/export_signing_assets.html#//apple_ref/doc/uid/TP40013306-CH8-SW1
When recreation of Certificates and Provisioning Profiles is needed:
Make sure you have appropriate privileges - you have to be team agent or admin:
1) Login to https://developer.apple.com with your developer credentials.
2) Go to Certificates, IDs & Profiles
3) Go to Certificates and remove the old one. Then Add new:
4) This is few step process, that requires you to create Certificate signing request. Just follow steps that are stated there. The last action in this step will be installing that Certificates - when ready, just click on it/them and they seamlessly get to your Keychain.
5) When finished with Certificates, open Profiles, find those marked with yellow triangle and edit them. Check the new certificate (and devices if you are creating Development profile as well). I personally prefer creating brand new profiles, as it it'll be easier to recognise older ones and new ones in Build settings later.
6) You now have to update your Xcode -> Preferences -> Accounts section and Xcode does this for you.
7) Last step - update Build settings in your projects according to your new profiles. You should be ready to validate you project now.
Non matching & non expired provisioning profiles found
I've been working over this issue and came across SO threads and I have not succeeded till now.
First off all, I'm using a free developer account so I am not able to login to the developer account portal and manage certificates and profiles.
I did not face any problem till now, after that I upgraded to Xcode 7.3.1
I am able to run the app on simulator but not on a real device
i am able to create a new project and run it on a real device, this only affects projects that I had created prior to upgrade
After that:
- Checked that certificates were valid under keychain access
deleted account from Xcode > preferences > accounts > appleIds
navigated to appleIds > view details : ensured that provisioning profiles were downloaded and non expired
deleted existing provisioning profiles from provisioned profiles directory and then created them again
cleared all profiles, deleted the account, recreated the account, triggered product > profile
verified that my iOS development cert is valid and did not create in Xcode
restarted Xcode at every stage of this process, as per multiple threads
For all of the posts I've seen, I'm sure this will help someone out there.
Go to project build settings > code signing > code signing identity
check that the provisioning profile you've made is set.
after I did this, I was still receiving an error. this time for entitlements. I browsed to project > capabilities > health kit (where the issue was) and found a 'fix issue' button. This solved the second half of the problem. good luck out there
I've build a new application which is going to support IOS 7. I got the new XCode 5 GM and tried to sign my apps using my fresh provisioning profile and distribution certificate, but i'm having trouble with distribution. I constantly get the following error:
"Invalid Code Signing Entitlements. The entitlements in your app
bundle signature do not match the ones that are contained in the
provisioning profile. According to the provisioning profile, the
bundle contains a key value that is not allowed:
'[XXXX.com.sample.company ]' for the key 'keychain-access-groups".
Also the same error for a key value called application-identifier.
Screenshot of the errror:
The solution lies in the new option in Xcode 5 which says provisioning profile. Just set the project target's provisioning profile to the right one and it'll work.
If you are like me and you think you tried EVERYTHING, archived your project over ten times, banged your head on the keyboard and still get this error. Please do yourself a favor and simply Restart XCode, it worked for me. Sometime Apple... I hate you.
I went through many of the steps above but what finally worked for me was refreshing my profiles in Xcode. Not sure why it was necessary since my app's distribution profile was showing up in the list already. Here are the steps:
Xcode Preferences
Accounts tab
Select your Apple ID
Hit the View Details button in the Apple ID detail panel
Hit the Refresh button in the lower left corner
In my case, i activated the same capabilities in Xcode that in Application services in developer.apple.com. Thats works for me
In my case (sorry) I switched "Team" to "None" in -> General -> Identity
In another case I needed to switch this identity from "None" to the developer account managing the identities and profiles.
Xcode sometimes messes up greatly with code signing, it seems. Or, we mere mortals simply aren't clever enough to understand what it is doing, of course. Don't give up, we're all going through some code signing torture at times!
In my case, I had to set correct Provision Profile for Release, and then had to restart Xcode. Before restarting, it had same provision profile, and didn't work. So, sometimes a restart can do miracles. Maybe this helps somebody.
If someone uses a GameCenter then check this section in your target. I worked with some old project and there were 2 errors (but everything worked fine). Disabling and enabling it back solved this problem.
Most likely this action adds Game Center entitlement to App ID and and handle it itself.
1.Go to project folder, delete *.entitlements files.
2.Then go yo in xcode project target -> build settings -> code signing entitlements - delete values
3.Clean
4.Run
Ah, this glorious error. For me whenever I see this error I check the following things:
1. Allow XCode to access your provisioning profile info all the time - If XCode keeps asking when you start it up to have access to your computer's private files so that it can get provisioning profile information with the options to allow access always, not now, or just one time - set it to ALWAYS ALLOW access
2. If you have any old entitlement files kicking around your project get rid of them and any sign of them - if you see a .entitlements file in your project delete it (or at least remove the reference to it if you aren't sure you are ready to outright delete it), then make sure the 'Code Signing Entitlements' line under the 'Code Signing' section in Build Settings is empty
3. Check your Application Services online and match them up with your Services in XCode for the app - Go to the Apple Member Center and check the App ID for your app, click on the app to see its 'Application Services' and see what you have checked, then go to XCode and check your 'Capabilities' section to make sure the two have the same list of Apple services on both
4. Make sure you assign a valid Provisioning Profile to your app before validating - double check your provisioning profile for your app in the Apple Member Center, make sure it isn't expired, has the right App ID with the correct bundle id and distribution. Download and click on the new provisioning profile to make sure XCode has it, or go to XCode > Preferences > Accounts > click on your account and 'View Details' then click the bottom corner button to Sync all the profiles to XCode. You should have the profile available to select now in the 'Code Signing' section. Once you have the correct provisioning profile then you can set the 'Code Signing Identity' lines to the correct option for that provisioning profile.
Note - if doing a distribution certificate it can help to set all the 'Code Signing Identity' lines to the identity you use for distribution including the debug lines
5. IF ALL ELSE FAILS - Clean your project and Restart XCode and some Apple magic may just work fine the next time you open your project and try to Validate
If you're building an old 3.1.5 project, Xcode 5 has some bugs which unfortunately makes Benjamin's answer impossible, as there are no Provisioning profiles to pick from. After many a late hour of tormented reading of Xcode project files I came up with this solution that worked for me:
In the Utilities pane (to the right) in Xcode 5, under project Document, change from Xcode 3.1-compatible to Xcode 3.2 compatible.
Enter your organization name.
Close project.
Open your project file, e.g. open -a TextEdit path/to/name.xcodeproj/project.pbxproj
Remove the two Distribution clauses (isa=XCBuildConfiguration).
Remove the two accompanying lines in buildConfiguration (one in PBXNativeTarget and one in PBXProject XCConfigurationLists)
Now you're ready to re-open, archive and submit to App store - voilà! It works again!
How I think it works
I assume this works because Apple somewhere along the line decided to drop the need for any separate distribution config, which is a good thing. When I archive, Xcode automatically code signs for distribution. That's the way it should have been implemented in the first place, it's just a shame that Apple can't make auto-migration part of the IDE; instead they force us developers to spend man-decades to make this stuff work.
I have been struggling with this problem for more than a day now, trying all kinds of solutions suggested here and elsewhere on the internet. Nothing worked...
But, I finally managed to solve the problem!
The problem I had was with an old app that I haven't touched in over 3 years, and now I was about to release a long awaited update. Since the time I released the app, Apple has been updating how the certificates and App Id works. They have introduced the concept of Team Id which seems to be recommended to use.
In particular, the Apple's "Certificates, Identifiers & Profiles" site, has seen a lot of changes since then.
There I realized that the Provisioning Profile I was using for App Store Distribution were connected to the App Id ED8xxxxxxx.com.rostsolutions.* but looking at the App Id for the game I was about to submit I notice that the App Id was ATMxxxxxxx.com.rostsolutions.Swisch. So the App Id prefix did not match!
That seemed to be the root of the problem. So what I did was to create a new Provisioning Profile connected to the App Id ATMxxxxxxx.com.rostsolutions.Swisch instead. Using that Provisioning Profile I successfully submitted my app to App Store and now I just keep my fingers crossed that everything else works fine at Apple's side.
(I first tried to connect to new Provisioning profile to the wildcard Id ATMxxxxxxx.com.rostsolutions.* instead, but that didn't seem to work).
But what puzzles me is that when I look at the old App in iTunes Connects and goes to Binary Details, it says that the App Id is ED8xxxxxxx.com.rostsolutions.Swisch. So why is the "Certificates, Identifiers & Profiles" page listing the App Id as ATMxxxxxxx.com.rostsolutions.Swisch?
My problem was solved by removing my Apple ID from Preferences->Accounts and then adding it back again. Then all my provisioning profile files showed up on the View Details utility panel. I was mistakenly choosing "Mac Team Provisioning Profile:*" instead of the actual distribution provisioning profile for the project thinking that it was a generic selection. Provisioning files must be specific to the project. Oh, and BTW, make sure your provisioning profile has the correct entitlements (for example, Maps). I managed to release an app with OSX Maps without the entitlement and Apple approved it -- but no Maps showed up on the production version!
In my case, I had the same problem, my solution was to change the 'Release Provisioning Profile' in the Build Settings before doing Archive. I do this twice, once for App Store distribution, and another one for Ad Hoc distribution. I also add a comment on my archives. My conclusion is that there is something broken about the "archive re-signature".
There is a very good tutorial for solving that problem on this website.
It says that this problem can occur when your Projects Bundle Identifier is different to the one you entered on the iTunes Connect Website.
I think xcode 5 uses "release" instead of "distribution" that you may created yourself.
If all above didn't work (in my case after couple of days no luck trying everything) I have only one Mac application. BE CAREFULL WITH REVOKE!
1) Revoke by hand all "Mac App Distribution" & "Mac Installer Distribution"
2) Clean relevant certificates and open-keys in Keychain (Warning: export before delete)
3) Restart Xcode
4) Go to (in Safari) developer.apple.com -> certificates etc.
5) Create CertificateSigningRequest.certSigningRequest in Keychain->Certificate assistant
6) Create by hand on developer.apple.com both "Mac App Distribution" & "Mac Installer Distribution" with your *.certSigningRequest
7) Provisioning Profiles -> Distribution -> create/fix custom provision for AppStore (I'm specially named it as "Mac provision profile for AppStore"
8) Xcode -> Settings -> Account -> Your account -> Refresh
9) Xcode Clean -> Archive -> Validate
I have been struggling with similar problem (I was building for Ad-Hoc distribution). Only thing that has changed since last successful deploy, was adding two devices to provisioning profile.
After double- and triple- checking all build settings, I regenerated provisioning profile (without changing anything), re-downloaded and it worked fine.
So note to self: if there is no logic explanation, you can always try good old IT voodoo.
I also recommend iPhone Configuration Utility, which despite its name, is useful for checking what provisioning profiles you have on computer.
ERROR ITMS-9000: “This bundle is invalid. New apps and app updates submitted to the App Store must be built with public (GM) versions of XCode 5.1.1 or higher and iOS 7 SDK. Do not submit apps built with beta software.
If multiple developers are using the same member center account. One of them can't use a certificate created by others cause they used a certificate request created using their computers.
You need to use a certificate created by you (certificate request
created using your computer).
Alternative, told them to send you the Developer Profile. not sure of the name. to use a certificate created on another computer.
Code signing Entitlements occur because of your resource does not contain Entitlements file in resources,Just go to build setting and search code signing Entitlements delete entry for debug and release, build project again you will see there is no error. Cheers
I had the same problem, but nothing written here worked for me. However, I found a simple way that worked for me. Here's how to do it:
1) In your Project and your Target(s) build settings, choose "None" for all Provisioning profiles, and choose "Don't Code Sign" for all Code Signing Identities.
2) Now, choose your Target and go to build settings. In Code Signing Identity Release setting, choose "iOS Distribution" for "Any iOS SDK". And then, in Provisioning Profile Release setting, choose your distribution profile for "Any iOS SDK". After that your Code Signing Identity Release setting should automatically change to "iPhone Distribution".
3) Archive your build and validate. Now it should work fine. That's it!
I am using Xcode 4.6.3.
I am getting this error messages while running the application in iPad,But first it was running correctly. Now we have renewed our license so i have changed certificate and
profile.still the same error appears
Please help me...
you need to follow this step:-
You Provisioning profile Generate with developer certificate from iTunes dev center.
remove old install App from device may be you Ipad contain old profile reference.
After connect your device to Xcode-Organizer->device->yuorIpad->Provisioning--check there old Provisioning profile is ther or not. if there then remove it.
In your target And Project check-> your Identifier is currect or not for example com.yourprofile.yourId
In Build setting you->code signing ->selection profile is correct identifier or not
Now just clean your Project. Build and run.
EDIT
Do not forget to Adding New testing Device ID into your new Generate Provisioning profile. in iTunes Dev there is Column to adding Device and also asking Device while you Generate Provisioning profile. May be you forget this step.
be sure that you are generating provisioning profile after adding device, or when you're just renewing profile.
And your provisioning profile must be linked with certificate, that you have in keychain.
(certificate+key)
All devices must be readded on demand, after renewing dev program (!)
In general, It's pretty sraightforward (just try it from the clean sheet, delete all the old stuff)
1) cert signing request
2) appid (if new app, if old just skip, optional - apns stuff)
3) certificates dev/distr (import them)
4) devices
5) provisioning profiles (import them)
in xcode choose in all positions needed profile, sometimes choosing parent option do not change profile for all fields of "Signing Identity" in xcode.
Deleting of old provisioning profiles is optional, it's not a problem when you have many of them
it's only problem when signing identities are more then one, ie: old expired and new one.
(In xcode 5 it will be easier to choose identity)
EDIT: it really seems like in build settings in code signing identity select options (some option) an old profile is chosen, and xcode gives this error.
