How do I use cgsize make?

I have been trying to use cgsizemake as follows:

I'm trying to make the frame of my image a different size using cgrectmake instead of changing the coordinates.

So far I have tried

 maincharacter.frame = cgsizemake (14, 14);

but I keep getting the error

assigning to cgrect from incompatible type CGsize

CGSize only accepts height and width

CGSize c=CGSizeMake(width, height);

If you want to set the frame size use CGRectMake

maincharacter.frame=CGRectMake(x-origin,y-origin, width, height);

below is an example of using CGSizeMake in a UIScrollView

var mainScrollView: UIScrollView?
var numPages = 3

override func viewDidLoad() {
    super.viewDidLoad()

    //this gets the screen frames size
    var fm: CGRect = UIScreen.mainScreen().bounds

    //creates a UIScrollView programmatically
    self.mainScrollView = UIScrollView(frame:CGRectMake(0, 0, fm.size.width, fm.size.height))

    self.mainScrollView!.contentSize = CGSizeMake(self.mainScrollView!.frame.size.width, self.mainScrollView!.frame.size.height * CGFloat(numPages))
 }

 CGSize viewwidth;
    viewwidth=[[UIScreen mainScreen] bounds].size;

this will help you to get device current resolution using cgsize.

viewwidth.width or viewwidth.height

as above u can use it. and also as below code

rightslide=[[UIView alloc]initWithFrame:CGRectMake(0,0, viewwidth.width, viewwidth.height)];

To use the variable c which is of type CGSize you would call c.0 and c.1 for the height and width respectively. I don't know why they named those properties 0 and 1 but you will have to take that up with Dennis Ritchie

Here is an example usage of CGSizeMake:

        var makeSize =  CGSizeMake(size.0, size.1)
        let circ = SKShapeNode(ellipseOfSize: makeSize)

Hope that helps.

maincharacter.frame must return (x, y, width, height) 4 parameters and CGSizeMake only have "width" and "height" 2 parameters. So You got an error. The solution is use frame.size, which returns 2 parameters to work with CGSizeMake(14, 14).

One solution would be:

CGRect frame = maincharacter.frame;
frame.size = CGSizeMake(14, 14);
maincharacter.frame = frame;
