There are a number of ways to implement the adapter pattern in Swift by leveraging inheritance, aggregation, or extensions.

Using the adapter pattern

When building an app, a program, or a web server, it is good practice to configure logging or analytics so it is easy to inspect program behavior at runtime. When running on a debugger or deployed on a user's device, or on a server, requirements for logging or recording analytics may change. During development, for example, it is not recommended to send analytics to the production server.

The adapter pattern is a great way to abstract and connect different logging or analytics infrastructures or classes, depending on runtime. It is based on the idea that classes will wrap your specialized...
