You can convert a string to an array by breaking it up by a substring using the
components(separatedBy:) method. For example, you can split a string up by a comma and space like this:
let str = "Andrew, Ben, John, Paul, Peter, Laura" let array = str.components(separatedBy: ", ")
That will return an array of six items, one for each name.
