title: Value of type 'UIView' has no member 'present' - how to invoke 'present'?
body: <p>i have a uiview file that i embedded into my tableview header </p>
  
  <p>(class TopHeader: UIView, UICollectionViewDelegate, UICollectionViewDataSource)</p>
  
  <p>If I use <code>present(_:animated:completion:)</code> i am getting: Value of type <code>TopHeader</code> has no member 'present'
  (  self.present(MyOtherViewController(doModes: [.photo]),  animated: true, completion: nil))</p>
  
  <p>How can I use the present method from there? Can I call a function that is in my uiviewcontroller from this uiview file? </p>
