Swift Patterns: Builders

The builder pattern isn't a common pattern in Swift and Cocoa development and you don't find it in any of Apple's frameworks. It is one of the Gang of Four design patterns and widely used in Java development.
As the name suggests, the builder pattern is aimed at object creation and configuration. The idea is simple. You pass the requirements of the object you want to create to a builder. The builder uses those requirements to create and configure the object. You could see the builder as a factory that is capable of creating a range of variations or representations of one or more types.

Thanks for the video! By the way I’d suggest removing your check in line 69 because parameters cannot be empty according to your code (f_png and dpr are always added).

Nice 👍

can you please share the code that you shown in the example?

Sure. You can find it on the Cocoacasts website (cocoacasts.com/swift-patterns-builders).
