CGPointMake in swift or CGPoint

Question

I want to move an UIImageView, I already did this in Objective-C and it completely worked. This was the code:

tank.center = CGPointMake(tank.center.x + TankX, tank.center.y + TankY);

TankX is set in viewDidLoad to 2 and TankY is set to 0. So the tank moves to the right. But when i want to do this in Swift it doesn't work. Swift code:

tank.center = CGPointMake(tank.center.x + TankX, tank.center.y + TankY)

I also tried CGPoint but I also can't get it working. I already saw this question: CGPointMake in Swift but I couldn't manage to use it.

Does anyone have an idea how to do this?

Edit: Error: Could not find an overload for '+' that accepts the supplied arguments

I edited my question the CGPointMake code gives an error. – Bas Jun 22 '14 at 14:05 — Bas, Jun 22 '14 at 14:05

I'd try this:

tank.center = CGPoint(x: tank.center.x + CGFloat(TankX), y: tank.center.y + CGFloat(TankY))

It converts TankX and TankY to CGFloats so they can be added to other CGFloats.

CGPointMake is deprecated in swift because it has structure initializers which do the same thing, jus as succinctly. The same is true of the other ...Make... functions as well. – David Berry Jun 22 '14 at 16:14

tank.center.x and TankX probably don't have the same type. Remember in Swift there is no implicity conversion between Int/Float/Double. You have to cast them explicitly, like: x = Double(y)

Their type is both float – Bas Jun 22 '14 at 14:06
If `tank.center` is `CGPoint`, `tank.center.x` would be `CGFloat`, which is the same as `Double` – Khanh Nguyen Jun 22 '14 at 14:08
