如何使用Swift将字符串中的字符存储到数组中

Question

Using Swift. How do I take a String and separate each character into an array?

var someString = "123"
var someArray = []

someArray[0] = "1"
someArray[1] = "2"
someArray[2] = "3"

Answer 1

Array has constructor that takes String and produce array of characters.

let someString = "abcde"
let array = Array(someString)

Answer 2

yes there are many ways to achieve this task old and best way is to use for in loop in the following way

 var someString = "123"
    var someArray : Array<Character> = []

    for character in someString {
        someArray.append(character)
    }
    println(someArray)
