Courses Plus Student 3,821 PointsIt keeps saying cannot convert value of type 'Double.Type' to expected argument type 'Double' and same for 'String'!
In the editor you've been provided with a struct named Location that models a coordinate point using longitude and latitude values.
For this task we want to create a class named Business. The class contains two constant stored properties: name of type String and location of type Location.
In the initializer method pass in a name and an instance of Location to set up the instance of Business. Using this initializer, create an instance and assign it to a constant named someBusiness.
struct Location {
let latitude: Double
let longitude: Double
}
class Business {
let name: String
let location: Location
init(name: String, location: Location) {
self.name = String()
self.location = Location(latitude: Double, longitude: Double)
}
let someBusiness = Business(name: String, location: Location)
}

struct Location {
let latitude: Double
let longitude: Double
}
class Business {
let name: String
var location: Location = Location(latitude: 20, longitude: 20)
// init properties into init function makes Swift ask you for a initial value when you instantiate an object from that class
init(name: String) {
self.name = name
}
}
let someBusiness = Business(name: "McDonalds'")
someBusiness.location = Location(latitude: 30, longitude: 30) // See value and reference types
print(someBusiness.name) // Prints McDonalds'
print(someBusiness.location) // Prints Location(latitude: 30.0, longitude: 30.0)
