Issue:
Xcode Archive & Export for iOS step fails with could not get scheme with name [NAME] from path /Users/.xcodeproj error messages.
Possible Solutions:
Make sure that the scheme exists and shared on Xcode settings.
Insert Recreate User Schemes Step if you haven't.
Toggle the scheme's build settings (Analyze, Test, Run, Profile, Archive) back and forth. Xcode sometimes does not register the scheme and its settings, this will make sure the scheme pops up in the source control changes.
Ensure that the Bitrise CI configuration is pointing to the correct scheme.
