swift how to change `CGRect(x: 400, y:500` to a stored variable

I'm righting a function to animate something I'm passing it a UIImageView (I shall be passing it the x and y once I sort this bit out) how do I change the CGRect(x: 400, y:500

if I change CGRect(x: 400, y:500 to CGRect(x: xdis, y:ydis I get build fail extra argument "width" in call but works fine as it is

    func UpAndDown(thingToAnimate:UIImageView)
  {
    UIView.animateWithDuration(5, delay: 0, options: .CurveEaseOut, animations: {
        let xdis = 30
        let ydis = 20
        thingToAnimate.frame = CGRect(x: 400, y:500 , width: thingToAnimate.frame.width, height: thingToAnimate.frame.height)

    }, completion: { finished in
        println("we moved")
})
Solution

  • This is probably happening because xdis and ydis are of type Int, whereas CGRect requires type CGFloat as parameters. Therefore, you need to make xdis and ydis of type CGFloat like so: 

    let xdis: CGFloat = 30
