Cannot push, pull or merge git. “Working copy has uncommited changes”

Question

I have recently set up a git repository on bitbucket, and have added an old project onto it. I have committed and pushed a change as a test, but now I face this problem.

Answer 1

Step 1:

git rm --cached ProjectName.xcodeproj/project.xcworkspace/xcuserdata/username.xcuserdatad/UserInterfaceState.xcuserstate

Step 2:

git commit -m "Removed file that shouldn't be tracked"
