I don't see what i did wrong here, please help me...

Can you please help me to correct this code? It works fine in playground returning what you ask.

functions.swift 
func coordinates(for location: String) -> (lat: Double, lon: Double) {
    switch location {
    case "Eiffel Tower":
        return (48.8582,2.2945)
    case "Great Pyramid":
        return (29.9792,31.1344)
    case "Sydney Opera House":
        return (33.8587,151.2140)
    default:
        print("error--location not found.")
        return (0,0)
    }
}

You will find in many cases that your code in playground works perfectly fine, but the Challenge Task wants you to code it in a specific way. In this challenge, you might want to read again that:

(Note: You do not have to name the return values).

Try with this one

// Enter your code below
func coordinates(for location: String) -> (Double, Double) {
  switch location {
    case "Eiffel Tower":
      return (48.8582,2.2945)
    case "Great Pyramid":
      return (29.9792,31.1344)
    case "Sydney Opera House":
      return (33.8587,151.2140)
    default:
      return (0,0)
  }
}

Hey there Jorge Solana

Thank you so much for your participation in the Community Forums. Your helpfulness and well explained responses are very appreciated. :smile:

If you could, however, place your responses as an "Answer" and not a "Comment", it will be better reflected in the Forum. Others can then see an answer has been provided, and have a peek if they like. Also, your answer can be up-voted and/or marked as "Best Answer" which add points to your profile.

Keep up the great work!
