Running version control in Xcode can give some troubles when setting up in an existing project. Having an existing project added to a new Git repository the Xcode keep saying UserInterfaceState.xcuserstate has changes.
The working copy “helloworld” has uncommitted changes. Commit or discard the changes and try again.
Committing the changes doesn’t help as it keep saying there is uncommitted changes.
You want Git to ignore the file, you can add it to the .gitignore file, but you have to remove the tracking. To stop tracking a file that is currently tracked, use git rm –cached.
git rm --cached ProjectFolder.xcodeproj/project.xcworkspace/xcuserdata/myUserName.xcuserdatad/UserInterfaceState.xcuserstate
git commit -m "Removed file that shouldn't be tracked"
Afterwards the .gitignore will take effect of UserInterfaceState.xcuserstate
