iOS Functions in Swift Adding Power to Functions Returning Complex Values

how can i slove this task

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)

you have the list of places. your function takes the name of a place as an argument and returns its lat/long coordinates. so you need a conditional statement that checks if the argument provided is in your list of places, if so return the coordinates, if not return 0,0.
