Cant Solve the Challenge

I get error in calling the class

classes.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: "James", location: Location)

Hi Parthiban, for Location, you have to set the latitude and longitude:

let someBusiness = Business(name: "James", location: Location(latitude: 1.7, longitude: 89.1))

If you are stuck, it's not a bad idea to type your code in a Swift playground. A lot of times, while typing, swift predicts the right answer. So if you typed Business( swift would automatically set the correct parameters.
