In Swift can I use a tuple as the key in a dictionary?

Question

I\'m wondering if I can somehow use an x, y pair as the key to my dictionary

let activeSquares = Dictionary <(x: Int, y: Int), SKShapeNode>()

If you don't mind a bit of inefficiency, you can easily convert your tuple to a string and then use that for the dictionary key...

var dict = Dictionary() 

let tup = (3,4)
let key:String = "\(tup)"
dict[key] = ...
