This code challenge looks ok for me but when I check it cannot compile it, is it a bug or I'm missing something ?

objects.swift 
struct Location {
  let latitude: Double
  let longitude: Double

  class Business {

        let name: String
        let location: Location

        init(name: String, latitude: Double, longitude: Double) {

            self.name = name
            self.location = Location(latitude: latitude, longitude: longitude)
        }

    }
}

let someBusiness = Location.Business(name: "Baketsu live", latitude: 11.7, longitude: 3.78)

You're not meant to provide the longitude or latitude in the init for the business but instead an already established instance of Location. Also, you have your class inside the struct whereas it should be outside the struct. So your code would look like this:

struct Location {
  let latitude: Double
  let longitude: Double
}

class Business {
  let name: String
  let location: Location

  init(name: String, location: Location) {
    self.name = name
    self.location = location
  }
}

let someBusiness = Business(name: "test", location: Location(latitude: 2.0, longitude: 2.0))
