Tip: Another way of writing the inRange function.

After watching the video of closures I noticed that the contains method on Swift Array types has a parameter that accepts a closure and so I attempted this:

   func inRange(position:Point, range:Int, target:Point) -> Bool {
        let availablePositions = position.surroundingPointsWith(withRange:range)

        if availablePositions.contains({targetPosition in return (targetPosition.x == target.x) && (targetPosition.y == target.y) }) {
            return true
        }else{
            return false
        }
    }

I'm guessing the built-in method itself is a loop, but I believe it serves a purpose in terms of readability. Thought I might share this quick tip if anyone wanted to know other ways of finding things in arrays.
