You can access the property characters of a String and use it to extract a array of your characters. If you want a array of String for each Character you need to use the method map to transform the [Character] in [String].

let str = "teste"
let strCharactersArray = Array(str.characters) // ["t", "e", "s", "t", "e"]
let strStringArray = str.characters.map{String($0)} // ["t", "e", "s", "t", "e"]

To go through each letter of the Voce String you can use the loop for in:

for character in str.characters {
    print(character)
}
