iOS Development Techdegree Student 1,221 PointsSome pointers needed
Wondering if the following is correct:
- Would utilizing a Switch be appropriated?
- Is my return correct (I know it is "void" as of now)
Any other pointers are welcomde
func coordinates(for location: String) -> (Double, Double) {
switch location {
case "Eifel Tower": (48.8582, 2.2945)
case "Great Pyramid": (29.9792, 31.1344)
case "Sydney Opera House": (33.8587, 151.2140)
default: (0, 0)
}
return ()
}

A switch
statement is perfect for this solution, yes! You will need to return the tuple in each case
individually. You also need to spell Eiffel correctly, else it'll not work.
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)
}
}
I hope that helps,
Steve.

iOS Development Techdegree Student 1,221 PointsWow! Have not seen a switch statement like that before where the return is included in each case. But it makes sense.
Thanks for the Eiffel typo (duh!) I confuse it often with the "Eifel Mountain Range" in west Germany :) that is spelled with one "f"

57,712 PointsThere may be a more elegant way of doing that; I'm no expert. You could set a local variable within the method, assign the tuple to it within each case
statement and return that after the switch
, perhaps.
I've walked in the Eifel range; very nice part of the world, not that the surroundings of the Eiffel Tower are shabby - also a lovely place!

iOS Development Techdegree Student 1,221 PointsOnce more - thanks for the additional information Steve - I'll look into the "local variable" posibility.
