[swift-users] [Possible bug] Initialising multiple instance variables from a closure

[Karl via swift-users]

Currently you can initialise a class instance variable from a closure:

let textView : UITextView = {
                let t = UITextView()
                t.translatesAutoresizingMaskIntoConstraints = false
                t.autocapitalizationType = .none
                t.autocorrectionType = .no
                t.spellCheckingType = .no
                return t
        }()

However, it doesn’t seem to be possible to return and initialise multiple 
variables from a closure:

        let (toolbar : UIToolbar, aButton : UIBarButtonItem) = {        // 
ERROR: Type of expression is ambiguous without more context
                let toolbar = UIToolbar()
                let aButton = UIBarButtonItem()
                return (toolbar, aButton)
        }()

Is this something which, in theory should be supported?

Thanks

Karl
