I\'ve had subversion running in Xcode for a while. The integration of subversion has always hung by a thread. However my subversion server has changed its ip address ... and
It's not Xcode, it's svn itself that still looks to the old reposotory. Try firing up a terminal, and cd'ing into the project directory. There use the switch svn command:
svn switch NewURL
then refresh or close/open the Xcode project.
I had similar problems when the dns name for my svn server changed (but keeping the same IP)
svn sw --relocate worked for me (from terminal on a mac). After the change, go to "Refresh entire project" from the SCM menu in xcode.
Good idea to do an svn info first though to check your repo URL. On my first attempt I entered the wrong FROM URL and the svn sw --relocate just does nothing, with no error reported.
The confusing thing in xcode was the the SCM - repositories browser worked fine after I updated the svn settings in xcode preferences, but my project was not fixed until after the --relocate business.
Try creating a new SCM repository and setting your project to the new one, and if that works, you can safely delete the old one.
I've run into a similar issue when relocating a Subversion repository would be completely ignored by XCode.
Here's a list of steps I've taken in order to force Xcode to update the repository path in my project:
Open up Terminal and go to your XCode project directory:
$ cd /path/to/your/project
Switch the Subversion working copy to the new URL (in the example below I also changed the SVN protocol but this is irrelevant):
$ svn switch --relocate svn://old_path svn+ssh://new_path
Fire up XCode, close your project's window and open up Organizer (⇧⌘2)
You should now see an updated SVN path under the Location heading under Source Control in the File inspector (the Utilities panel).
If you go to Organizer, you should also see the project back in its place under the Projects tab and a new item under the Repositories tab.
The environment I've tested this solution in: Mac OS X Mountain Lion + XCode 4.4.1
You need to use the --relocate option for the svn switch command if you are just changing hostnames or ip addresses.
So, something like this:
svn sw --relocate svn://brian@123.123.123.123/mypath svn://brian@122.122.122.122/mypath
