Issue description

When running the step, it starts ignoring the project path I configure the step with (points to a workspace file, not an xcodeproj file), and tries to use the xcodeproj instead, resulting in a failure due to package resolution issues.

Code signing asset management by Bitrise
Reason: Using Bitrise-managed code signing assets with API key because Automatically managed signing is disabled in Xcode for the project.

Steps to reproduce

You'll need to try building the project through support.

FWIW, I can't get the same error to reproduce locally.
