nothing in return?

hey guys,

So we finished writing the code. We created our struct, our functions, our loops, and returned the results.

Now i dont understand why the results dont appear anywhere. shouldnt we be getting x1y1 x1y2 x1y3 x2y1 x2y2 x2y3 etc etc in the debug area?

heres the code:

let x1 = 0 let y1 = 0

let coordinate1: (x: Int, y: Int) = (0,0) coordinate1.x

struct Point { let x: Int let y: Int

func surroundingPointsWith(withRange range: Int = 1) -> [Point] {
    var results: [Point] = []
    for xCoord in (x-range)...(x+range) {
        for yCoord in (y-range)...(y+range) {
            let coordinatePoint = Point(x: xCoord, y: yCoord)
            results.append(coordinatePoint)
        }
    }
    return results
}

}

Thanks for your help !

The method surroundingPointsWith is only declared, but it isn't executed.
