Issue with swiftpackagemanager key

[Eric-Catalyst]

Adding the swiftpackagemanager key cause the following line to be added to the gitignore:

*.xcodeproj

This prevents the project files for Xcode from being incorporated into git even though the following exceptions are also present (due to the Xcode key):

!.xcodeproj/project.pbxproj
!.xcodeproj/xcshareddata/
!.xcodeproj/project.xcworkspace/
!.xcworkspace/contents.xcworkspacedata
