What is wrong with my solution code in this struct exercice ?

class Business { let name: String let location: Location

init(n: String, l: Location) { self.name = n self.location = l } } let someBusiness = Business (n:"Rio de Janeiro", l:(latitude: 10.0, longitude: 5.0))

classes.swift 
struct Location {
    let latitude: Double
    let longitude: Double
}
class Business { 
  let name: String
  let location: Location

  init(n: String, l: Location) {
    self.name = n
        self.location = l
    }
}
let someBusiness = Business (n:"Rio de Janeiro", l:(latitude: 10.0, longitude: 5.0))

Hey there,

you almost got it right, good job! :) The only problem is that when you create an instance of Business you have to give it an instance of Location as the second argument. So the only thing you have to do is write Location in front of the parentheses with the values for latitude and longitude .

Like so:

struct Location {
    let latitude: Double
    let longitude: Double
}
class Business { 
  let name: String
  let location: Location

  init(n: String, l: Location) {
        self.name = n
        self.location = l
    }
}
let someBusiness = Business(n:"Rio de Janeiro", l: Location(latitude: 10.0, longitude: 5.0))

I hope that helps! :)
