Now that we've refreshed ourselves on the basics of Swift programming, we can get started with the first series of design patterns: creational patterns.
We use creational patterns to hide the complexity of creating instances of fully featured objects, decouple different part of your applications, and gear your code toward high maintainability.
In this chapter, we'll dive into those traditional patterns, from theoretical to concrete examples, through detailed use cases. We'll see how they're adapted from traditional languages such as Java, and how we can enhance them with the unique features of Swift.
We'll start with two very common and widespread patterns, the singleton and the lazy initialization. We'll follow up through the chapter with the most powerful and useful creational patterns in Swift.
In this chapter, we'll dive deep into the following topics:
- The singleton pattern
- The factory method pattern
- The abstract factory pattern
- The builder pattern
- The prototype...
