Just a quick question for clarification. What will happen to these? Do we have
to provide the default value ourselves?
class ViewController : UIViewController {
@IBOutlet weak var view1: UIView?
@IBOutlet weak var view2: UIView!
}

Hi all,
Right now, the following two declarations are equivalent:
struct S {
var x: Int?
}
struct S {
var x: Int? = nil
}
That is, mutable bindings of sugared optional type (but not Optional<T>!)
always have a default value of ‘nil’. This feature increases the surface area
of the language for no good reason, and I would like to deprecate it in
-swift-version 5 with a short proposal. Does anyone feel strongly about giving
it up? I suspect most Swift users don’t even know it exists.
