No matter what I put in .gitignore I can not get git to ignore the UserInterfaceState.xcuserstate file below:
$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
modified: .gitignore
modified: CalFoo.xcodeproj/project.xcworkspace/xcuserdata/wcochran.xcuserdatad/UserInterfaceState.xcuserstate
I am using/editing the .gitignore file listed on this post.
I tried everything to match the pattern including the exact pathname: CalFoo.xcodeproj/project.xcworkspace/xcuserdata/wcochran.xcuserdatad/UserInterfaceState.xcuserstate to no avail.
This particular problem arises from the workflow where Xcode is used to create the initial git repo and the .gitignore file from here is added afterwards. A more general answer to ignoring previously tracked files in git can be found from this question (I guess I never found this post in my search since it didn't have "gitignore" in the title).
You can only ignore unversioned files but that file is already known to git.
If you want git to track that file, there is no need to tell git to ignore it.
If you don't want git to track that file use git rm and your ignore rule will start working.
Caution: git rm will remove the file. Use git rm --cached to remove from the repo but not from the disk.
