Swift string to array of single character strings

Question

How can I convert a string into an array of single strings? So String -> [String]

If I do Array(myString) it results in an array of characters. I tried flatmap (or compactMap in the latest Xcode beta):

stringArray = Array(myString).flatMap { $0 as? String }

Then I get a warning: "Cast from 'Character' to unrelated type 'String' always fails" and `print(stringArray) results in [].

Is this possible?

Edit: this was already answered in a non-accepted answer in this question: Convert Swift string to array

That answer results in an array of characters, not an array of strings. — koen, Mar 16 '18 at 22:42
Both flatMap and map seem to work, why is the latter preferred? — koen, Mar 16 '18 at 23:41

You can do it like as follows... Initialize a new string inside the map.

let test = "thisIsATest"
let array = test.map( { String($0) })

another simple method is: let anotherArray = Array(test) – Martin Muldoon Mar 16 '18 at 23:09

that will result in an Array of Characters, whereas the question was to get Array of Strings. – Harsh Mar 16 '18 at 23:10
