i have solved the challenge however i am not totally accepting my solution , i feel there is something missing

In this challenge, we have the following geographical coordinates

Eiffel Tower - lat: 48.8582, lon: 2.2945 Great Pyramid - lat: 29.9792, lon: 31.1344 Sydney Opera House - lat: 33.8587, lon: 151.2140

Declare a function named coordinates that takes a single parameter of type String, with an external name for, a local name of location, and returns a tuple containing two Double values (Note: You do not have to name the return values). For example, if I use your function and pass in the string "Eiffel Tower" as an argument, I should get (48.8582, 2.2945) as the value. If a string is passed in that doesn’t match the set above, return (0,0)

my answer is

// 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)

Hello Mohamed,

Your function looks good, and if it allows you to pass the challenge then you are good to go.

The requirements are there and everything seems perfect.

Good Job.

It's a shame that Treehouse has placed the beloved Sydney Opera House in the Pacific Ocean instead of in Australia... There is another hemisphere guys! ;)
