ios - Get Screen size in Swift as Integer -

for positioning element random in screen within boundarys need resolution/screen size in swift. fount out how cggraphics. unfortunately have calculate bit , need type uint32, not cgfloat. cannot use casting way. ideas?

let screensize: cgrect = uiscreen.mainscreen().bounds let screenwidth = screensize.width //what want let screenheight = screensize.height-arc4random_uniform(screensize.height) 

if want random x , y positions element can this:

let screensize = uiscreen.mainscreen().bounds let randomxpos = cgfloat(arc4random_uniform(uint32(screensize.width))) let randomypos = cgfloat(arc4random_uniform(uint32(screensize.height)))
