在数组 SWIFT 3 中查找匹配元素 [重复]

Question

我有两个用字符串填充的数组，我希望在两个数组中识别匹配的字符串。例如。

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

我想要的结果是

["Dog", "Chicken"]

提前致谢

Answer 1

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)
    }
}
