How to find the uncommon elements from two arrays in Swift

Answer 1

import Foundation

let arr1 = [1, 2, 7, 5, 16, 19]
let arr2 = [1, 8, 5, 12, 19, 52, 103, 150]

let uncommonArr1 = arr1.filter { !arr2.contains($0) }
let uncommonArr2 = arr2.filter { !arr1.contains($0) }

let uncommon = uncommonArr1 + uncommonArr2

print(uncommon)
