Swift break文とcontinue文による繰り返し処理の中断

llet names = ["Taro", "Jiro", "Hanako", "Jun", "Miki"]

// 名前の配列と検索する名前を引数で受け取り、
// 配列にその名前が存在する場合はその名前を返却し存在しない場合は空文字を返す

            // 検索する名前が見つかった時点で繰り返し処理全体を終了する
            break
        }
    }
    return ret
}

let searchJun = searchName(names: names, target: "Jun")
print(searchJun)

// >>> Jun

let numArray = [1, 3, 6, 8, 10, 13, 15]

// 数字の配列と除外する倍数の基となる数字を引数で受け取り、
// 除外した後の配列を引数で返す
func excludeMultipleNum(numArray: [Int], excludeNum: Int) -> [Int] {
    var ret: [Int] = []
    for num in numArray {
        if num % excludeNum == 0 {
            // excludeNumの倍数の場合、処理を中断し次の繰り返し処理へ
            continue
        }
        ret.append(num)
    }
    return ret
