Where to add the latitude and longitude parameters?

Not sure where... thanks!

classes.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 someBusiness = Location(name: String, location: Location)

Hello Paul:

The challenge wants you to create an instance of Business, and not of location. That's basically all you need to do to finish it. You have everything set up the right 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 someBusiness = Business(name: "Walmart", location: Location(latitude: 20, longitude: 20))

Good luck.
