That's a cool hack! For a lighter way to distinguish overridable methods that
one shouldn't ordinarily call, did anyone consider approximating "protected"
(or as called in Objective-C speak, "private extension") methods with public
class methods?
public class UIView {
public class func _layoutSubviews(_ view: UIView)
}
This way, they become overridable, won't show up in the editor auto completion
list for a given instance, and can be called… but definitely make you think
twice before you do!
