Don't know whats going wrong but can't figure this out

I have to assign the initialiser to create instance to apply it to constant named someBusiness???

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 someBusiness = Business(name: "Bangpiper", location: Location)

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
