配列内のCGPointsの座標が同じかどうかを確認する方法は？

Question

配列中のCGPointsが同じx/y座標を持つかどうかチェックできますか？

ここにコードがあります。

enum Three { 
    case pointOne(point: CGPoint) 
    case pointTwo(point: CGPoint) 
    case pointThree(point: CGPoint) 

    func coordinatesXY() -> [CGPoint] { 
     switch self { 
      case .pointOne(let point): return [point] 
      case .pointTwo(let point): return [point] 
      case .pointThree(let point): return [point] 
     } 
    } 
}

単に==

enum Three { 
case pointOne(point: CGPoint) 
case pointTwo(point: CGPoint) 
case pointThree(point: CGPoint) 

    func coordinatesXY() -> CGPoint { 
     switch self { 
     case .pointOne(let point): return point 
     case .pointTwo(let point): return point 
     case .pointThree(let point): return point 
    } 
    } 
} 


let point1 = CGPoint(x: 100, y: 100) 
let point2 = CGPoint(x: 100, y: 100) 

if point1 == point2{ 
    print("yes") 
    } 

Three.pointOne(point: point1).coordinatesXY() //Gives you a CGPoint 
Three.pointTwo(point: point2) 

func checkEquality(pointA : CGPoint, pointB : CGPoint){ 

     if Three.pointOne(point: pointA).coordinatesXY() == Three.pointTwo(point: pointB).coordinatesXY(){ 
     print("yes") //Prints yes 
    } 


} 

//Prototype of comparing two coordinates 

var arrOne = [Three]() 
var arrTwo = [Three]() 

arrOne.append(Three.pointOne(point: point1)) 
arrOne.append(Three.pointOne(point: point1)) 
arrOne.append(Three.pointOne(point: point1)) 
arrOne.append(Three.pointOne(point: point1)) 
arrOne.append(Three.pointOne(point: point1)) 
arrOne.append(Three.pointOne(point: point1)) 

arrTwo.append(Three.pointTwo(point: point2)) 
arrTwo.append(Three.pointTwo(point: point2)) 
arrTwo.append(Three.pointTwo(point: point2)) 
arrTwo.append(Three.pointTwo(point: point2)) 
arrTwo.append(Three.pointTwo(point: point2)) 
arrTwo.append(Three.pointTwo(point: point2)) 



for eachA in arrOne{ 

    let arrayOneElement = eachA.coordinatesXY() 
    for eachB in arrTwo{ 
     let arrayTwoElement = eachB.coordinatesXY() 
     checkEquality(arrayOneElement, pointB: arrayTwoElement) 
    } 
}
