在数组SWIFT 3中查找匹配的元素 [英] Find matching elements in array SWIFT 3

问题描述

我有两个用字符串填充的数组，希望在两个数组中标识匹配的字符串。例如，

I have two arrays filled with strings and am hoping to identify the matching strings in both arrays. Eg.

var ArrayOne = ["Dog", "Cat", "Chicken"]
var Array Two = ["Dog", "Elephant", "Chicken", "Sheep"]

我想要结果为

["Dog", "Chicken"]

预先感谢

推荐答案

var ArrayOne = ["Dog", "Cat", "Chicken"]
var ArrayTwo = ["Dog", "Elephant", "Chicken", "Sheep"]

var ArrayThree = [String]()
for animal in ArrayOne {
    if ArrayTwo.contains(animal) {
        ArrayThree.append(animal)
    }
}
