I was looking for a way to put my existing project under source control, and I looked at this question, but it looks like that solution only worked with Xcode 4.0 because I can’t find a way to do what is advised. I also looked at this question, but that solution doesn’t work either because my project isn’t currently under source control. How can I get my existing project under source control?
Edit
I want it to be a git repository, not subversion.
you can do it in terminal using:
cd /to/app/folder
This should then be picked up in Xcode, you may need to close and re-open
Hope it helps
