Xcode 6 Swift code completion not working

Question

Using Xcode 6 GM seed my code completion has stopped working. It was working the other day. I was trying to get the unwind segue work around to work. I had made an Objc head

Answer 1

If your code completion problem is only with UI classes (e.g. UIImage, UIDevice), then you just need to add "import UIKit".

Swift files will NOT have code completion for UI classes unless there is an "import UIKit".
