How to initialize char array with random characters in Swift

Answer 1

import Foundation

let size = 10 // Array size
let characters = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"

func initializeCharArrayWithRandomCharacters(size: Int, characters: String) -> [Character] {
    var charArray = [Character]()
    for _ in 0..<size {
        if let randomCharacter = characters.randomElement() {
            charArray.append(randomCharacter)
        }
    }
    return charArray
}

let charArray = initializeCharArrayWithRandomCharacters(size: size, characters: characters)

print(charArray.map { String($0) }.joined(separator: " "))
