Pretty close! First: The initialization method should include both the name and location. Not just location. The part where you are adding the "self." within the init method is referencing the properties of the class. Not the struct above. The location property on the class already knows to use the lat and long since you told it to be of type "Location".

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

Second: Your initialization of the "someBusiness" constant will be outside of your class declaration. The part you're missing is needing to pass the location as an argument. 

let locale = Location(latitude: 123.32, longitude: 123.32)
let someBusiness = Business(name: "Apple", location: locale)

All of it together:

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 locale = Location(latitude: 123.32, longitude: 123.32)
let someBusiness = Business(name: "Apple", location: locale)
