Question

So I have converted an NSURL to a String. So if I println it looks like file:///Users/... etc.

Later I want this

Answer 1

NOTICE: pay attention to the url, it's optional and it can be nil. You can wrap your url in the quote to convert it to a string. You can test it in the playground.
Update for Swift 5, Xcode 11:

import Foundation

let urlString = "http://ifconfig.me"
// string to url
let url = URL(string: urlString)
//url to string
let string = "\(url)"
// if you want the path without `file` schema
// let string = "\(url.path)"
