If you write your code using Xcode it will do a lot of the heavy lifting for you. For example, the second you typed that opening parentheses you would have saw how the instance is created. Either way, the Business class has a name property and a location property. name is simply a string and location is an instance of Location. Location has two properties, latitude and longitude that are type Double.

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: "Awesome Business", location: Location(latitude: 39.720705, longitude: -122.34375))
