I accidentally deleted the repository in the XCode Organizer. I’ve set up the repository again but how can I tell the project which one it should use because I get this error:
The repository “(null)” could not be reached.
I think it was a little bit easier in Xcode 3.
After setting it up again by using “Add working copy…” from the Repository-Tab in the Organizer – restart Xcode4. This worked for me a minute ago with Xcode 4.2
