Keep getting errors on my code

I'm on the Object - Oriented Lesson for Swift. My problem has to do with Class & Struct's. I think the problem is that I'm not understanding the last paragraph of what he is asking. It sounds like he wants me to pass an "Instance" as the "location" 's data type within the parameter. He hasn't shown me that in any lesson so far.. So I'm really confused.. Any help would be much appreciated!

objects.swift 
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 someLocation = Location(latitude: 34.5, longitude: 23.56)

let someBusiness = Business(name: "LLC", location: someLocation)

The the instance you tried is correct. Th only problem is, your code is that in the initializer saying self.location=Location isn't correct. It should be self.location=location; Here's what the whole code should look like in your way:

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 someLocation = Location(latitude: 34.5, longitude: 23.56)
let someBusiness = Business(name: "LLC", location: someLocation)

Hope that this helped!
