Answer 1

Neither answer currently works with Swift 4, but the following can cover OP's issue & hopefully yours.

extension String {
    var wordList: [String] {
        return components(separatedBy: CharacterSet.alphanumerics.inverted).filter { !$0.isEmpty }
    }
}

let string = "Hello, Playground!"
let stringArray = string.wordList
print(stringArray) // ["Hello", "Playground"]

And with a longer phrase with numbers and a double space:

let biggerString = "Hello, Playground! This is a  very long sentence with 123 and other stuff in it"
let biggerStringArray = biggerString.wordList
print(biggerStringArray)
// ["Hello", "Playground", "This", "is", "a", "very", "long", "sentence", "with", "123", "and", "other", "stuff", "in", "it"]
