Builder in Swift

Builder is a creational design pattern, which allows constructing complex objects step by step.

Unlike other creational patterns, Builder doesn’t require products to have a common interface. That makes it possible to produce different products using the same construction process.



Usage examples: The Builder pattern is a well-known pattern in Swift world. It’s especially useful when you need to create an object with lots of possible configuration options.

Identification: The Builder pattern can be recognized in a class, which has a single creation method and several methods to configure the resulting object. Builder methods often support chaining (for example, someBuilder.setValueA(1).setValueB(2).create()).

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