Fix "Could not reset index file to rev. 'HEAD'" in Xcode

I am trying to start my Xcode and receive the warning message:

“Project” is currently in conflict. Do you want to abort the current operation?

When I press abort, I get this error:

Could not reset index file to revision ‘HEAD’.’

I have been unable to pull from repositories or checkout other branches. I attempted to resolve this issue using the terminal, however, it was unsuccessful.

Try running the following command in the terminal:

git reset

If that doesn’t work, try running:

git reset --hard

This should reset your repository to the latest commit. If you still have issues, you may need to delete and re-clone your repository.
