[swift-evolution] Tuple

[Fabian Ehrentraud]

Hi,

I have a problem with tuple parameter types in a closure. Is this a language restriction or a bug in the Swift compiler? I used the Swift shipped with Xcode beta 3, also tried in Swift 2.2.

let d: [Int: String] = [1:"1", 0:"0"]
let e = d.sorted(isOrderedBefore: { e1, e2 in e1.0 < e2.0 }) // works
let f = d.sorted(isOrderedBefore: { (k1, v1), (k2, v2) in k1 < k2 }) // does not compile


Best,
Fabian
