To answer your original question the challenge won't pass as there is no such type as str in Swift, here are some valid types just to name a few.

  • String
  • Int
  • Double
  • Dictionary

For this challenge you're asked to allow a parameter with a type of String so you should instead have the following.

func greeting (person: String)
