Invalid code signing certificate

[Thumbler1983]

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

Launch build on dev branch

Expected results

Build completes successfully

Actual results

Build fails during "Set up code signing identities" step with the following error:

Build failed :|
Invalid code signing certificate

Nothing has been changed in the configuration before the builds start failing. It suddenly happened the 16th of October.
I've already tried to generate a brand new certificate and provisioning files but it did not work.

Build id (optional)

Hi @Thumbler1983, I noticed that you've specified the Xcode version as the edge version, which is currently Xcode 15.1. Please set it to Xcode 14.3.1, which was the version you were using when the build was successful

Thank you so much @dtrdic, it worked. But... it seems more or less like a workaround. I use Xcode 15 locally and ad hoc builds work just fine. Is there anything I can do in the future to solve this issue? For the time being your fix is good enough anyway. Thanks again.

I'm glad that helped!:) You can still use other Xcode versions, but the key takeaway here is that if your app is building successfully locally with a specific set of versions (Flutter, Xcode, CocoaPods, etc.), you should set the build environment in your CI/CD pipeline with those same versions, like this you will avoid compatibility issues
