Hello,
i'd like to know if i did it properly. is there a more easy way to complete this exercice?
i find it quite bad to declare a variable called "var geo = (0.0,0.0)" and then assigning all my case to this variable
// Enter your code below
func coordinates(for location: String) -> (Double, Double) {
var geo = (0.0,0.0)
switch location {
case "Eiffel Tower": geo = (48.8582, 2.2945)
case "Great Pyramid": geo = (29.9792, 31.1344)
case "Sydney Opera House": geo = (33.8587, 151.2140)
default: return (0,0)
}
return geo
}

You can do this by returning the value directly within the case clauses rather than just assigning the values to a variable. Like this:
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)
}
}

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