What have I done wrong here?
// Enter your code below
func coordinates: String(for location: Double) {
coordinates = (Eiffel Tower: 48.8582, 2.2945, Great Pyramid: 29.9792, 32.1344, Sydney Opera House: 33.8587, 151.2140)

2,393 PointsI am fairly new to learning this myself but I do see what the error is, so hopefully I can help.
To begin with, the very beginning is written correctly, but the rest is not written correctly. The beginning should have a syntax as follows --> func coordinates (for location: String)
<--- this declares a function, names that function coordinates
and then the following says, for
is the EXTERNAL name and location
is the LOCAL name, then you declare the this
(for location)
statement is a string by typing : String
. You then need to assure that you are returning the proper value, by doing as follows --> (Double, Double)
<-- this says that both values that will be returned will be Double
values.
A big reason this will not work is because you have not added a switch
statement, which will essentially tell the compiler to go through the following. I have written the correct way to write it below but i do not recommend you copy and paste it. Take your time and go back through the videos, its a fairly simple function, you just need to take your time and break it down. This adding of a switch statement into a function will come up in a few lessons so again don't just copy and paste. make sure you understand completely.
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)
}
}
