EDIT: I have struggled an entire day with this. I think I might know at least the root cause of it. Not sure how to fix it yet though. App-FastlaneRunner.log

Later EDIT: I have removed FastlaneRunner from Build Phases -> Copy Files section and it finally made the error go away, but I am unsure of the implications image

I have this behaviour on an M1 mac. I have an intel based macbook as well and I got paranoid and did a fresh install of the OS and was able to reproduce it there as well. Not sure how other people are not getting it either, or if I am doing something wrong. But I am just doing the most basic steps and able to repro every time 🤷‍♂️

Last EDIT (I promise): It’s most probably an Xcode issue. more specifically - the latest one (13.3) I built it with Xcode 13.0 and it doesn’t have the Copy resources option, like 13.3 has

If you run the underlying xcodebuild command, the problem becomes apparent quite quickly:

xcodebuild -scheme FastlaneRunner -project ./fastlane/swift/FastlaneSwiftRunner/FastlaneSwiftRunner.xcodeproj -destination 'generic/platform=macOS' build

The underlying Fastlane project has two copy files phase that both copy the same file:

Both copy phases do exactly the same thing, the only difference being their name. I was able to get my fastlane scripts to run by deleting either one of the phases, which of course makes fastlane complain that it’s not up to date. I would assume this is a bug in the implement of FastlaneRunner but I would be curious to get context from the implementer as to why there’s two copy phases in the Xcode project.

So what’s the solution?

Is there any fix or should we abandon Fastlane.Swift altogether at the moment?

I just started my fastlane integration and noticed, that fastlane asks on lane execution if I want to update the FastlaneSwiftRunner project. If I deny this fastlane runs, if I accept it, I get this error.

So I added fastlane swift to my project and will run for now with --disable_runner_upgrades
