  let latitude: Double
  let longitude: Double
}

class Business {
let name: String

Hi Alfie,

You are close! The problem is you didn't define the Location data in your Buisiness call. See below:

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: 12, longitude: 25))

Then you can test someBusiness like so:

//Testing someBusiness
someBusiness.location.latitude //returns 12
someBusiness.location.longitude // returns 25
someBusiness.name // Returns Walmart

ThanksThomas Dobson, the code works now
