Command-line build fails with "provisioning profiles not found"
Archiving Xcode project fails with provisioning error
Missing signing certificates in Xcode

Symptoms

The issue manifests it's self in one of several ways:

Running your app on a device results in an error referencing "code signing" or "expired signing certificates"

Building from the command line (or using a continuos integration system, such as Jenkins) fails with a error similar to this:

Check dependencies
Code Sign error: No unexpired provisioning profiles found that contain any of the keychain's signing certificates

Archiving an app fails with "code signing" or "expired signing certificates" where a run or build work correctly.

Often the project may have several configurations and sometimes only a subset will fail. Deleting and regenerating provisioning profiles has no effect.

回答1:

CODE_SIGN_IDENTITY verification script.

Often in set ups that use version control the project.pbxproj can be merged in such a way that two CODE_SIGN_IDENTITY lines can be inserted. This seems to cause Xcode problems under certain situations (like command-line builds or archiving).

A tell-tail sign is lines similar to this in the project.pbxproj file (right-click on the project and select "Show Package Contents…")

"CODE_SIGN_IDENTITY[sdk=iphoneos*]" = "iPhone Developer";
CODE_SIGN_IDENTITY = "iPhone Distribution";

Deleting one of these lines will let you select the correct value in Build Settings and the project should once again build correctly.

I have created simple script to help diagnose this issue it can be found here: https://github.com/rjstelling/Xcode-Project-Validate

I got this code sign error with an Open Source Github project which I only wanted on my own device (not in store or anything) and I don't have a paid membership account.

In that case it's meanwhile (since XCode 7) possible to configure and allow your app as unsigned but trusted.

I had a similar problem which I could solve after a lot of wasted hours. So writing my solution here in case it helps someone.

My iOS app, which I have been developing and deploying/updating regularly for past 5 years, recently ran into a similar issue where final "Distribute App" via XCode Organizer started showing an error "Code Signing for MyAppName.app failed - see distribution logs for more information". The distribution logs have no information whatsoever.

After a lot of trial-and-error, I found that the certificate used for code signing had somehow gone corrupt. I deleted the certificate and it fixed the problem. Hope this helps someone.
