Not sure why I am unable to input Double(s) into the instance assigned to someBusiness?
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: "Jamal", location: 20.123444, 22.433333)

Martin Granger's answer is correct:
All structures have an automatically-generated memberwise initializer, which you can use to initialize the member properties of new structure instances. And must call the initializer with the struct parameters.
The second bug is:
Missing } before the let.
The correct code it:
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.init(name: "Jamal", location: Location(latitude: 20.123444, longitude:22.433333))

I believe your problem is that you've set the location value to a (Double,Double) rather than an instance of Location.
Try this:
let someBusiness = Business(name: "Jamal", location: Location(latitude: 20.123444, longitude: 22.433333))
I really hope it helps you.
