Swift array element map

Question

I have array [[one, two, three, four]] and I want to convert array in [["one", "two"," three", "four"]] without using a loop in Swift 3.

I tried

let myArray = array.map { String($0) }

But this is returning ["[one, two, three, four]"].

Answer 1

Array([[one, two, three, four]][0].map({String($0)}))

Answer 2

In your case, you actually have two arrays. You have an array OF arrays of whatever one, etc. are.

Try:

let result = array.map { $0.map { String($0) } }
