In the realm of software development, particularly within Swift-based applications, dependency injection (DI) remains a cornerstone technique for achieving loosely coupled, testable, and maintainable code. By decoupling components and their dependencies, developers can write cleaner, more modular applications. This blog delves into the essence of dependency injection in Swift and unfolds the benefits and implementation strategies of a containerised approach for managing dependencies.

Unraveling Dependency Injection

Dependency Injection is a design pattern that allows a class or structure’s dependencies to be injected from the outside rather than hard-coded within.

This practice is instrumental in Swift development, where the emphasis on type safety and testability is paramount.

Why Dependency Injection?

1. Testability: DI makes unit testing a breeze. By injecting mock dependencies into classes during testing, developers can easily isolate and test individual components.

2. Flexibility and Scalability: Changing or updating dependencies doesn’t require modifications to the dependent class, allowing for greater flexibility and…
