713 PointsThis code challenge is not accepting my code in functions and scope in swift.
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 doesnβt match the set above, return (0,0)
// Enter your code below
func coordinates(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)
}
}

Your syntax is correct, but if you have a look at the error message the challenge gives you when you "Check Work"
Make sure you accept a single parameter of type String in your function declaration with the correct argument labels
It shows that you may have missed the part of the instructions that state the parameter should have "an external name for
", which your code doesn't have... you only have a local name, so you don't have the "correct argument labels"
If you need, you should review the Argument Labels Video for a quick refresher on external
and local
names.
Other that that... Nice job!
Keep Coding! :)
