Sorry Step means step to export archive, not related to package 'pedometer'. After struggled with 4 days with this problem as changing a bunch of ios configuration, I just delete Xcode 15.3 and install 15.2 and succeeds. I also deleted Xcode 15.3 and install 15.3, It didn't work as well, which means there should be some bug in Xcode 15.3 deployed March 24. Please look through this problem..
