Hi nader,

Firstly, I have fixed your code formatting so please have a read of Posting Code to the Forum.

You're simply missing names for your return tuple which is what the challenge is looking for, as you can see below; naming tuples is the same as naming a parameter for instance.

func greeting(person: String) -> (greeting: String, language: String) {
  // ...
}

For more information, have a read of the below link which has helped several other students.

Happy coding!
