I had my project in subversion and was trying to get it to work with Xcode, but kept running into error 155007 whenever I tried to commit my changes from Xcode. After trying many different ways to get to the bottom of this, here are the steps that worked:
- Delete your local copy (cd myxcodeproject; rm -rf .)
- Delete the “build” folder from the server
- svn co https://svnserver/path/trunk/project .
Now you should see .svn folders in every directory of your local project (you don’t see them if you use the “Export” function of the SCM panel from Xcode). At this point, you should be able to edit and commit your changes directly from Xcode.
