Xcode source control view history modified files fail

I used Xcode source control to connect with SVN server.

After check out the source, I executed the “commit”, “update”, all work fine.

  • Exclude a file/directory from SVN in Xcode with SCM
  • xcode commit missing file or directory
  • Adding assets to Xcode problem
  • Merging Xcode project files
  • How to version control overlapping folder structures?
  • Xcode thinks a remote svn repos is git
  • But when I click Source Control > History, and click show modified files, then show an alert dialog:

    The source control operation failed,because no working copy could be found.

    Make sure the file is in a valid working copy and try again.

    Any advice is appreciated, thanks.
