How to Create a CGSize in Swift?

Question

How can I create a CGSize in Swift? This is what I have tried so far (but doesn't work):

var s:CGSize = {10,20}
var s:CGSize = CGMakeSize(10,20)

Your first attempt won't work because C structs don't exist in Swift. You need:

let size = CGSize(width: 20, height: 30)

Or (before Swift 3 only, and even then, not preferred):

let size = CGSizeMake(20,30)

(Not MakeSize).

IIRC, the docs recommend the first way rather than the Objective-C convenience methods. – Abizern Dec 28 '14 at 21:34
Yes, that's true. Named parameters are also much nicer. – jrturton Dec 28 '14 at 23:09
@Machado the answer already works in Swift 3, what do you mean? let vs var is nothing to do with the Swift version – jrturton Dec 29 '16 at 07:19
The problem is `let size = CGSizeMake(20,30)`. The method `CGSizeMake` is unavailable in Swift. – Machado Dec 29 '16 at 11:00
Fair enough, I've added a comment in the answer – jrturton Dec 29 '16 at 12:27

As of Swift 3 you can no longer use CGSizeMake

The solution for Swift 3 is var size = CGSize(width: 20, height: 30)

they should say that instead of "CGSizeMake is unavailable in Swift" > this is misleading – Saik Caskey Oct 30 '17 at 12:56
