iOS Code Signing fails

[gnomezgrave]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Flutter (Dart)

Steps to reproduce

1. Have automatic code signing setup according to the documentation.
2. Setup build triggers as "tag"
3. Create a tag in the repo and it works fine.
4. Add a new target to the XCode project (ref: ImageNotification)
5. Create a new release/tag in the repo
6. Wait...
7. And 😢

Expected results

The workflow should be completed without errors as before.
Previously, it worked fine with a single target (Runner). But, now after adding a new target (and also having a proper bundle identifier for that target) fails the build.

Actual results

Workflow fails during the build phase with the below error.

Hello @gnomezgrave, it appears that the latest build was successful and you were able to resolve it independently. If you require further assistance, please connect with us with your build ID.

Yes, I reverted the changes for my XCode project using Git history to the last time it worked.

[gnomezgrave]

So, in case someone else faced a similar issue, here are the things that I reverted.

I reverted to the last commit that worked, took a backup of the ios folder, reverted back to the latest code (which doesn't work).
Then I got the diff of the project and the workspace to detect the change.

ios/Runner.xcodeproj/project.pbxproj

This is the XCode project version.

- LastUpgradeCheck = 1430;
+ LastUpgradeCheck = 1300;

- compatibilityVersion = "Xcode 15.0";
+ compatibilityVersion = "Xcode 9.3";

I don't know if the above changes are needed. But these changes are!

For each release, debug, and profile config in the project:

     CLANG_WARN_QUOTED_INCLUDE_IN_FRAMEWORK_HEADER = $inherited;
     CLANG_WARN_UNGUARDED_AVAILABILITY = YES_AGGRESSIVE;
+    CODE_SIGN_IDENTITY = "Apple Development"; // This line
     CODE_SIGN_STYLE = Automatic;
     CURRENT_PROJECT_VERSION = 1;

You can open the project in a text editor and add these lines. Somehow, setting the signing on the UI didn't add these into the project (correctly).

I hope this helps someone, someday 😇
