Here’s my solution to the Challenge: Stroke.
dieShape.lineWidth = 10 NSColor.greenColor().set() dieShape.stroke()
This code follows on from my solution to Challenge: Gradients. This means you’ll need the following code for it to work (which needs to be before the code snippet above).
let dieShape = NSBezierPath() dieShape.appendBezierPathWithRoundedRect(dieFrame, xRadius: cornerRadius, yRadius: cornerRadius)
