Usage examples: The Facade pattern is commonly used in apps written in Swift. It’s especially handy when working with complex libraries and APIs.

Identification: Facade can be recognized in a class that has a simple interface, but delegates most of the work to other classes. Usually, facades manage the full life cycle of objects they use.

The following examples are available on Swift Playgrounds.
Kudos to Alejandro Mohamad for creating the Playground version.
