Should I git ignore xcodeproject/project.pbxproj file?

Question

in a XCode project, I offen got xcodeproject/project.pbxproj file changed, but useless info for me, it for compile.

Should I git ignore this file and xcodeproject/pr

Answer 1

I found that I also need to preserve the xcworkspace file(s). If didn't, project with a sub-project broke.
