2,186 PointsStuck again on initializer methods...Challenge 2 someBusiness
I can't see what's wrong or more accurately, I can't see how to fix it. Here is the compiler error message I get.
Playground execution failed: error: test.xcplaygroundpage:10:20: error: use of unresolved identifier 'Business' let someBusiness = Business(name: "craps", location: someLocation) ^~~~~~~~ Please help.
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: "craps", location: Location(latitude: 4.3, longitude: 51.2))

23,970 PointsYour class is inside your structure, that is why you are getting the error. Move the class outside the struct and you have it
struct Location {
let latitude: Double
let longitude: Double
}
class Business {
var name: String
var location: Location
init(name: String, location: Location) {
self.name = name
self.location = location
}
}
let someBusiness = Business(name: "My House", location: Location(latitude: 34.0, longitude: 26.0))

2,186 PointsHmm. Thanks that totally fixed it. Looking back through some of the course examples I'm not sure how missed that classes can't be inside structs. Thanks again.
