Keep on getting errors

I keep on getting 4 errors:

  1. in my first for loop it says: "Cannot call value of non-function type 'Int'"
  2. at the curly bracket at the end of the first for loop it says: "Expected ',' separator"
  3. at the return statement, it says: "Expected expression in list of expressions"
  4. the curly bracket ending the func gives an error: "Expected ')' in expression list

Don't understand, my code is exactly the same as Pasan's code. Here is my code:

struct Point { let x: Int = 2 let y: Int = 2

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
}

}

Never mind, I found my error thank you. /*my first for loop was missing a bracket for xCoord in (x-range...(x+range) should be: */

for xCoord in (x-range)...(x+range)

//my code now works!
