How to convert a String (numeric) in a Int array in Swift

Question

I\'d like to know how can I convert a String in an Int array in Swift. In Java I\'ve always done it like this:

String myString = \"123456789\";
int[] myArray = n         


        

Answer 1

Swift 3: Functional Approach

1. Split the String into separate String instances using: components(separatedBy separator: String) -> [String]

Reference: Returns an array containing substrings from the String that have been divided by a given separator.

2. Use the flatMap Array method to bypass the nil coalescing while converting to Int

Reference: Returns an array containing the non-nil results of calling the given transformation with each element of this sequence.

Implementation

let string = "123456789"
let intArray = string.components(separatedBy: "").flatMap { Int($0) }
