Difference between returning Void and () in a swift closure

Question

Whats the difference between these closures?

let closureA: () -> ()

and

let closureB: () -> Void

Answer 1

Same. It's just a typealias so it works exactly the same.

typealias Void = ()

Sounds like Erica Sadun and Apple are trying to stick with Void: http://ericasadun.com/2015/05/11/swift-vs-void/
