Git ignore file for Xcode projects

Question

Which files should I include in .gitignore when using Git in conjunction with Xcode?

Answer 1

I've added:

xcuserstate
xcsettings

and placed my .gitignore file at the root of my project.

After committing and pushing. I then ran:

git rm --cached UserInterfaceState.xcuserstate WorkspaceSettings.xcsettings

buried with the folder below:

/.xcodeproj/project.xcworkspace/xcuserdata/.xcuserdatad/

I then ran git commit and push again
