I feel as if the task wasn't explained properly.
struct Location {
let latitude: Double
let longitude: Double
}
class Business {
name: String
location: Location
init(/* It says "In the init method pass in a name" what does it mean by that?) */ {
}
}
let someBusiness = Business(name: "Some Name") // Confused...

class Business {
name: String
location: Location
// You pass in the name and location as parameters here
init(name: String, location: Location) {
// You then need to assign these arguments into the properties of the class
self.name = name // self.name references the class property and name references the passed in argument
self.location = location // same syntax as above
}
}
// You then need to create an instance of the business
let someBusiness = Business(name: "MyCo", location: Location(latitude: 100, longitude: 120)) // arbitrary coordinates for Location instance
Hope that helps and let me know if you still have questions.

4,342 PointsI'm sorry I'm still confused... also if thats what I need to do, why didn't he tell me those instructions, as you just did? There was a lot left unsaid on his part :/

4,342 Pointsfor example, location: Location() I didn't know needed a separate sent of parenthesis. I feel like some of these things are just expected for us to know.
