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"

  • @MrCoder: The thread that you linked to is about splitting a string into separate *words* which are separated e.g. by a space. – Martin R Oct 15 '14 at 12:17

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

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

    More precisely, `Array` has a constructor that takes a `SequenceType`, and `String` happens to implement that protocol. Compare http://stackoverflow.com/a/25921323/1187415. – Martin R Oct 15 '14 at 12:47

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)
