Custom UIButton focus not working properly in tvOS

Question

I have a UIViewController like this

  +View
       button1
       button2
       backgroundImage
       ScrollView
              scrollBackgroundImage
              scrollButton1
              scrollButton2

All the buttons are of custom type if initial focus is on button1 then no matter what I do focus never goes to buttons that are inside scrollView. If initial focus is on button2 then focus never goes to button1/button2.

If I change all buttons to type System then focus starts working as expected.

Answer 1

Actually, focus does go between button1 and button2.

If you change button type to Custom, it means that you should handle visual focus updates yourself ( for example, in didUpdateFocusInContext(context: UIFocusUpdateContext, withAnimationCoordinator coordinator: UIFocusAnimationCoordinator) method ).
