Hands-On Design Patterns with Swift

Setting Objective-C names from Swift

When you write Swift class names, we follow the recommendation of not prefixing our class names or extensions with a two or three letter code. However, back in Objective-C, those conventions are quite important for a number of reasons, but principally to avoid naming collisions with other objects from different frameworks.

Let's consider the following code snippet that defines a movie:

class Movie {    let title: String    let director: String    let year: Int    /* Initializers */}

As it is right now, it is not possible to use it in Objective-C as the Movie object doesn't inherit NSObject. Also, because you're exposing your class to Objective-C and not following the naming conventions of Objective-C with the prefix, ...
