I have been reading that unwind segue\'s are bugged in Xcode 6. I am using Xcode 6.1.1 and I use swift.
I use the \"Back\" button that is put by the navigation controlle
I found that I could not drag from the UITableViewCell to the Exit object on the View Controller on the Storyboard.
Exit
Solution was to first add an appropriate IBAction in code. Once an IBAction exists, the drag target will light up.
-(IBAction)prepareForUnwind:(UIStoryboardSegue *)segue { }
