Mastering Swift 2 Programming (Video 56)

The video tutorial introduces the facade pattern, explaining its role in providing a unified interface to complex subsystems. It demonstrates setting up a console application with user, file, and article repositories. The tutorial then guides through implementing the facade pattern by creating a connect class to streamline operations, making the code cleaner and more efficient. Finally, it updates the application to use the new facade pattern API, highlighting its benefits in readability and reduced code lines.
