Mastering Swift 2 Programming (Video 54)

The video tutorial explains the factory pattern, a design pattern that abstracts object creation, allowing the type of object to be determined at runtime. It demonstrates how to implement this pattern in a console application that uploads files to different cloud accounts based on file type. The tutorial highlights the benefits of using the factory pattern, such as reducing explicit instance creation and improving code manageability. The video concludes with a successful test of the implementation and a preview of the next topic, the adapter pattern.
