Naming Parameters and Tuples Challenge Issue

func greeting(#person: String) { println("Hello (person)") }

Call the greeting function and pass it the String "Jerry"?

I have tried adding in greeting(person:"Jerry")

make sure you are calling the function outside of the function itself. also you are missing the slash for interpolation:

func greeting(#person: String) { 

  //add the slash for interpolation
  println("Hello \(person)") 

}

greeting(person: "Jerry")

It works thanks!

Create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.):

func greeting(person: String) -> (language: String, greeting: String, person: String) { let language = "English" let greeting = "Hello (person)" let person = "Tom"

var result = greeting(person: greeting)

return result

}

I am not sure what I am doing in this one either?

Hi Shaun,

The Code should be:

func greeting(person: String) -> (language: String, greeting: String) { 
     let language = "English" 
     let greeting = "Hello \(person)    
     return (language, greeting)
}

var result = greeting("Tom") //You pass the string Tom when calling the greeting function.
