Replacing text in a string using replacingOccurrences(of:)

Paul Hudson       @twostraws

It's easy to replace text inside a string thanks to the method replacingOccurrences(of:). This is a string method, and you tell it what to look for and what to replace it with, and you're done.

For example:

let str = "Swift 3.0 is the best version of Swift to learn, so if you're starting fresh you should definitely learn Swift 3.0."
let replaced = str.replacingOccurrences(of: "3.0", with: "4.0")

That will make replaced equal to "Swift 4.0 is the best version of Swift to learn, so if you're starting fresh you should definitely learn Swift 4.0.”
