Wrote some simple code to study structs as I'm struggling with them. Will you check out my little method?

//Goal is to make a method to calculate the distance from one's location to the destination, using simple Coordinate custom Type

struct Coordinate {
    let long: Int
    let lat: Int

    func computeDistance(x: Int, y: Int) -> Coordinate {
        let distanceOfX = x - long
        let distanceOfY = y - lat
        let results = Coordinate(long: distanceOfX, lat: distanceOfY)
        return results


let myLocation = Coordinate(long: 4, lat: 5)
let distanceToStore = myLocation.computeDistance(x: 6, y: 2)

You could do all this in a init method

struct Coordinate {
    var distanceOfX: Int
    var distanceOfY: Int

   init(long:Int, lat:Int, x: Int, y: Int){
        self.distanceOfX = x - long
        self.distanceOfY = y - lat

//Assign the struct here:
let distanceToStore = Coordinate(long: 4, lat: 5, x: 6, y: 2)

//And then all you got to do is call:
