Unable to embed UIScrollView over UIView in another scene using Xcode 8

Question

I have an existing iPad app (portrait mode) where I am trying to add landscape mode to Xcode. I was able to do this on the first simple view seen below, changing the class in Xcode to UIScrollView, and UIView fell into the line below (I believe that XIV was added to UIView, but not sure if it). The scrollview function works great in landscape mode.

When I try to do the same for the next scene, this will not allow me to reorder again, as shown in the following image; I am not sure why this will not allow the same thing:

Any ideas? Is there any other way to do this?

UPDATE Here is an image showing the position of an attempt to insert a UIScrollView into a UIVIewController (Book information is a UIViewController, viewing book details is a UIView):

Answer 1

None of the answers solved the problem of modifying an existing application, so I asked Apple for technical support. They also did not decide, but they gave me some documents that could be looked at. @Aragunz probably came close, suggesting that this is a problem / in Xcode 8. My only option is to rewrite the storyboard from scratch while preserving the existing classes.

Select Book Details UIViewControllerin the storyboard, and then simply select the root mode. Delete it and then drag UIScrollViewon UIViewController. Your root view should now beUIScrollView

Note. I personally prefer the following hierarchy of views:

|---UIView
     |---UIScrollView
         |---UIView //(to act as a container)
              |---UIView
              |---UIView
              |---UIView
              |---UIView

Allows you to scale the application as needed quite easily, as well as allowing autorun to quite easily control the setting of the size of the contents of your UIScrollView
