4,009 PointsThis was a tricky exercise for me, but I did figure out what it is asking for. After the "->" (which is where you specify what the function will return), you need to name the two strings that will be returned using a colon to separate the name and the type (e.g. found: Bool, description: String).You will also need to make sure the function returns the two values (greeting, language).

Courses Plus Student 1,278 PointsI have tried this code:
func greeting(person: String) -> (language: String, greeting: String){ let languages = "English" let greetings = "Hello (person)"
return language - greeting
}

4,009 PointsOsman, your code looks good except for the return line. The syntax for returning a tuple is parentheses with the values separated by a comma. You are also missing a backslash before person in your greetings constant [(person)].

38,442 PointsCan you post what you've tried, then we can try to help from there. Likely, it's a matter of just rewatching the video or viewing the documentation to get a better understanding.
