Drawing Text Die Faces

Open DieView.swift and jump to drawDieWithSize(_:). Add the following code below the block that draws the die dots. The new code will run if intValue is not in the range 1...6.

            if intValue == 6 {
                drawDot(0, 0.5) // Mid left/right
                drawDot(1, 0.5)
            }
        }
        else {
            var paraStyle = NSParagraphStyle.defaultParagraphStyle().mutableCopy()
                              as! NSMutableParagraphStyle
            paraStyle.alignment = .CenterTextAlignment
            let font = NSFont.systemFontOfSize(edgeLength * 0.5)
            let attrs = [
                  NSForegroundColorAttributeName: NSColor.blackColor(),
                  NSFontAttributeName: font,
                  NSParagraphStyleAttributeName: paraStyle ]
            let string = "\(intValue)" as NSString
            string.drawInRect(dieFrame, withAttributes: attrs)
        }
    }
}
