Template Method in Swift
Template Method is a behavioral design pattern that allows you to defines a skeleton of an algorithm in a base class and let subclasses override the steps without changing the overall algorithm’s structure.
Usage of the pattern in Swift
Usage examples: The Template Method pattern is quite common in Swift frameworks. Developers often use it to provide framework users with a simple means of extending standard functionality using inheritance.
Identification: Template Method can be recognized by behavioral methods that already have a “default” behavior defined by the base class.
