So it turns out Xcode has two different Team ID options when you do an Xcode Archive + Export (what the bitrise Xcode Archive step does, it performs an Archive then an Export on it to generate the IPA, same what you do in Xcode.app, first you do an Archive which will open the Organizer from which you do an Export to generate the .ipa).

The bitrise Xcode Archive step has two separate options for these:

• team_id which is used during Export ( https://github.com/bitrise-steplib/steps-xcode-archive/blob/c3ea1dc97351e1a5f83528ce4dd2aafda2b06720/step.yml#L77 )
• and force_team_id which is used during Archive ( https://github.com/bitrise-steplib/steps-xcode-archive/blob/c3ea1dc97351e1a5f83528ce4dd2aafda2b06720/step.yml#L115 )

Based on your build log ( https://app.bitrise.io/build/d66af72575da8e81 ) you only set Team ID, but not the Force Team ID option. If you set both that should work.

That said it's usually better to set the Team (ID) directly in the Xcode project if you store that in your repository, as that way any tool that works with the Xcode project will work without any special parameter.

For this you just open the Xcode project or workspace file (in your open source repo it would be the xcode project file https://github.com/rpuls/dashboardwrapper/tree/master/ios/dashboardwrapper.xcodeproj ), and in Xcode.app you set the Team in project settings like this:

Once you do this you should run an Archive in Xcode to be sure there are no other configuration issues in the project, and if that's successful just quit Xcode.app and commit+push the project file changes into the repo.

With this setup all the tools should work out of the box, e.g. https://github.com/bitrise-io/codesigndoc which is prompted on the bitrise.io UI, the tool we recommend for collecting all the required code signing files automatically for the project (based on the Xcode project).
