structs.swift
struct Tag {

Hi there, in Swift 3.0 you can use this method:

import Foundation

let string = "Hello World!"
let formattedString = string.replacingOccurrences(of: " ", with: "") // result: "HelloWorld!"

Thank you Konrad, I followed your suggestion, and it works fine with xCode. But, the import does not work with web editor available on Techdegree. It gives me the following error:

swift_lint.swift:18:19: error: value of type 'String' has no member 'replacingOccurrences' return "(title.replacingOccurrences(of: " ", with: "")) by (author).Filed under (tag.name)"

Also, what about swift 2.0 ?
