I’m trying to set up a UIViewController than can host a number of different UIViews as long as they adhere to a given protocol. I’ve worked through getting things set up to make the compiler happy, but I’m getting a runtime error loading the view controller from the storyboard. Below is the relevant code.
How do I specify the class in the storyboard so it will load correctly? Or perhaps there’s a different way to construct this all so it will work?
protocol MediaItemView {
}
class PhotoMediaItemView : UIImageView, MediaItemView {
}
class VideoMediaItemView : VideoPlayerView, MediaItemView {
}
class MediaItemViewController<T where T: UIView, T: MediaItemView> : UIViewController {
private var currentMediaItemView :T?
}
let mediaItemViewController =
self.storyboard?.instantiateViewControllerWithIdentifier("MediaItemViewController") as!
MediaItemViewController<VideoMediaItemView>
Storyboard has a view controller with the Class set to "MediaItemViewController"

Could not cast value of type 'UIViewController' (0x10d1dfd60) to 'Media_Tools.MediaItemViewController<Media_Tools.PhotoMediaItemView>' (0x1193fc038).
