Question

Out of the various stock UIKit classes, which ones are considered focusable by default by the Focus Engine on tvOS?

Answer 1

Per David House on Big Nerd Ranch, the following UIKit classes are focusable:

• UIButton
• UITextField
• UITableView
• UICollectionView
• UITextView
• UISegmentedControl
• UISearchBar

Note that this is different from which classes conform to the UIFocusEnvironment protocol; the above are what would return true on canBecomeFocused
