i need help.. Again

so now ive spend a lot of time trying to get this right. and it still gives me "your code could not be compiled" even though the compiler doesnt return any errors, neither in Xcode or Treehouse...

Honestly, i dont understand why theres even a struct in this assignment.

So i hope one of you guys can explain a bit for me, Appreciate it!

objects.swift 
struct Location {
    let latitude: Double
    let longitude: Double

    class Business {
        let name: String
        let location: Location

        init(latitude: Double, longitude: Double) {
            self.name = "Business name"
            self.location = Location(latitude: latitude, longitude: longitude)
        }
    }

}


let someBusiness = Location(latitude: 2.2, longitude: 2.3)

Hi Daniel,

A couple of things: 1) The Business class should not be nested in the Struct. 2) Your Business initializer will have two parameters: name (of type String) and location (of type Location -- the struct) 3) The class properties name and location will be passed the argument values from the initializer

Here's the code:

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: "Acme Hardware", location: Location(latitude: 10, longitude: 10))
