swift 遍历

最简单的一个遍历数组

for 随便起个名字 in

升级

上面的看不懂的话，这个应该会简单点

import UIKit
let interestingNumbers = [
    "prime": [,,,,,],
    "prime1": [,,,,,],
    "prime2": [,,,,],
]
var largest =
for (kind,numbers) in interestingNumbers {
    for number in numbers {
        if number > largest {
            largest = number
        }
    }
}
print(largest)

//////////////////////////
let hehe = [:[,],:[,]]
var xx =
for (name,array) in hehe {
    for number in array {
        print(number)
    }
}
////////////////////////

var intArray = [,,,]
for int in intArray {
    print(int)
}
