How to split a string into an array: components(separatedBy:)

Written by Paul Hudson    @twostraws

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.
