Would be very happy if someone could help me with this task :)

classes.swift 
struct Location {
    let latitude: Double
    let longitude: Double
}

class Business{
let name: String
let location: Location

    init(name: String, location: Double) {
        self.name = name; self.location = Location
    }
}

let someBusiness = Business(name: "Nespresso", location: 10.5)

struct Location {

    let longitude: Double
}

class Business {
    let name: String
    let location: Location

    init (name: String, location: Location) {  //  pass in an instance of Location
        self.name = name
        self.location = location  //  set location equal to the stored property location, not the struct 'Location'
    }
}

let someBusiness = Business(name: "The Bizz", location: Location(latitude: 35.6, longitude: 77.2))
  //  finally create an instance for Business and pass in Location

Heres the code you're looking for Eli

Hi Eli,

You're almost there! It looks like your problem is in your init() method. You've declared location as type "Double" when this should be a struct Location. You'd also need to assign the value of the variable "location" to self.location rather than "Location"

init(name: String, location: Location) {
        self.name = name; self.location = location
    }

Also,

You'll need to create an instance of Location to pass into the "location" parameter for someBusines instead of a Double value.

let location = Location(latitude:10.0, longitude:23.0 )
let someBusiness = Business(name: "Nespresso", location:location)

I really hope this helps!!!
