I am not able to create an outlet between my UIViewController and a UIContainerView in IB. In the the past I've used UIView for the IBOutlet definition and IB let me create the outlet. In iOS 9, Xcode 7 no can do in either Swift 2 or Objective-C. UIContainerView is not defined in either Swift 2 or Objective-C and IB will not make a connection using UIView for the definition.
Anyone have any ideas?
Workaround I found: Make an IB connection with UIContainerView from Storyboard. After the connection is made (and build errors come up), change the type from UIContainerView to UIView. Xcode wouldn't let me connect it to a UIView outlet, but after changing the type to UIView, the connection made remained and project built. This has to be a Xcode 7 bug since UIContainerView connections in Xcode 6 are UIView.
