You were off to a great start, but you forgot to initialize name, in a similar way you did location. After you initialize that you create an instance and set it to a constant named someBusiness:

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 = Business(name: "some business", latitude: 81.93727, longitude: -48.49860)
