I\'ve been trying unsuccessfully to connect to an https assembla svn repository with the new xcode 4 IDE for an iPhone project I\'m working on.
I was able to connect
I had a similar problem; was working in XCode 3 blah blah...
I followed all the instructions here and here but still it was hanging.
The problem was that my svn username and my mac OS username and password were the same. Once I'd changed the name of my svn user it worked!
Hope this prevents anyone else spending a day's work on this
