快速将int范围数组转换为字符串数组

Question

How can i convert an range int array into an string array?

Like this range int array:

let data = [Array(1...9), Array(0...59), Array(0...59)]

To an string array like:

let data = [["1", "2", "3",.....], ["0","1", "2", "3",...], ["0","1", "2", "3",...]]

Answer 1

尝试这个

data.map{ $0.map(String.init) }

Answer 2

let data = [Array(1...9), Array(0...59), Array(0...59)]

var stringArray = Array<Array<String>>()

for array in data {
    var subArray = Array<String>()

    for item in array {
        subArray.append(String(item))
    }

    stringArray.append(subArray)
}

Answer 3

You can try like this when you get the value from array.

Code Snippets:

let num = [1, 2, 3]
let data = [num, num, num]

let value = data[0]

for x in value {
    print(String(x))
}
