Using variables in CGRectMake, Swift, UIkit

For an App I'm making i need to use variables to change the size and position of objects (Labels). I've tried

var example = CGRectMake(0, 0, 0, 100)
, hoping it would ignore the zeros (Not really thinking it would though). I then tried:

var example = 100
Label1.frame = CGRectMake(20, 20, 50, example)

I changed the syntax a bit, adding "" and replacing the
etc, but nothing worked... I don't get what I'm doing wrong here... Help!


CGRectMake takes CGFloats for all of its arguments. Your sample code should work fine if you specify that example is supposed to be a CGFloat, using a type identifier:

         //  v~~~~ add this...
var example: CGFloat = 100
Label1.frame = CGRectMake(20, 20, 50, example)

Otherwise, swift infers the type of example to be Int, and the call to CGRectMake fails, cuz it can't take an Int as a parameter...
