The quiz won't pass when no spaces in between curly braces e.g `{set}` but no compiler error

Would this mean that when writing Swift code in quiz input box we must follow certain style guides? It'll be nice to have it somewhere handy, because I was bit confused when didn't get any error/warning from compiler

This is just a minor discrepency between the current version of Xcode and the accepted answer for this code challenge. But yes, you are right, this works in an Xcode playground using version 10 and above.

protocol User {
  var name: String {get}
  var age: Int {get set}
 }
