Can't pass values to a class

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: "starbucks", location: 11.144, .12.222)

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: "starbucks", location: 11.144, .12.222)

Hi there,

You want to create an instance of Location when you make the someBusiness instance.

A Location is made up of a latitude and longitude; use the values you have done.

So, rather than this (and remove the dot before the second number):

let someBusiness = Business(name: "starbucks", location: 11.144, 12.222)

Create a Location:

let aLocation = Location(latitude: 11.144, longitude: 12.222)

But rather than assigning into a constant, just pass it into the Business class with the required location: name that the Business class is expecting:

let someBusiness = Business(name: "Starbucks", location: Location(latitude: 11.144, longitude: 12.222))

I hope that makes sense.

Steve.
