title: How to add a project to subversion using Xcode 7 and change user crendentials
body: <p>Earlier import option was available under repository section in organizer but in Xcode7 it's not so. How to add a project to svn?</p>
  
  <p>My svn repository was setup with different user credentials and now when i try to commit with new user credentials,it asks for older user's password with old username disabled for change.
  I have also added a new account in xcode preferences, still it is looking for the older username-password.
  How can i move ahead with new user credentials?</p>
