CGPointMake in Swift

Question

How to use CGPointMake in Swift? Is there an equivalent for it? I am getting an error:

Use of unresolved identifier 'CGPointMake'

Basically, I am trying to assign a position to a Sprite Kit node and cannot figure out how to do it in Swift.

class PlayerSpaceship: Spaceship {

    func launchMissile() {

        var missile = Missile.playerMissile()

        // This line gives above mentioned error.    
        missile.position = CGPointMake(0.0, 0.0) 
    }
}

I was able to compile `var p = CGPointMake(0, 0)` in Swift just fine. Is it possible that you just haven't included the CoreGraphics framework? — Aaron Golden, Jun 05 '14 at 21:27
I'm pretty sure CGPointMake only exists because NeXTSTEP came out before C99: `(CGPoint){0.0,0.0}` — Steven Fisher, Jun 05 '14 at 21:40
@AaronGolden, thanks. Indeed, adding `import CoreGraphics` solved the issue. — Rafał Sroka, Jun 06 '14 at 07:42
Did @sjeohp's suggestion of using `CGPoint(x:0, y:0)` fix the problem *without* importing CoreGraphics or is there some other reason you accepted that answer? — Aaron Golden, Jun 06 '14 at 19:00

Use CGPoint(x: Float, y: Float)

You call it a little differently, without the make.

CGPoint(x: 10, y: 20)

Xcode 6.3.1 shows 4 different Swift initializers for CGPoint. They are:

CGPoint()
CGPoint(x: CGFloat, y: CGFloat)
CGPoint(x: Double, y: Double)
CGPoint(x: Int, y: Int)

In the code it should looks like this (Xcode 6.1):

let point: CGPoint = CGPoint(x:10,y:10)

`let point = CGPoint(x: 10, y: 10)` should be enough in Swift. – Cœur Oct 06 '18 at 03:33

Or also, you can use CGFloat type for CGPoint

 CGPoint(x: CGFloat, y: CGFloat)
