Trouble importing foundation into swift... Xcode 6 beta -

i brand new xcode. thank reading this.

i'm attempting used language, i'm messing code importing foundation , creating simple nsrect. however, i'm getting error when try create nsrect.

here's code:

import foundation import uikit let rect = nsrect(x: 50, y: 50, width: 100, height: 100) 

and receive error saying "use of unresolved identifier 'nsrect"." doing incorrectly?

thank help!

use cgrect instead of nsrect . nsrect cocoa, if project mac app use import cocoa.

import foundation import uikit let rect = cgrect(x: 50, y: 50, width: 100, height: 100)
