Swinject is a lightweight dependency injection framework for Swift.
Dependency injection (DI) is a software design pattern that implements Inversion of Control (IoC) for resolving dependencies. In the pattern, Swinject helps your app split into loosely-coupled components, which can be developed, tested and maintained more easily. Swinject is powered by the Swift generic type system and first class functions to define dependencies of your app simply and fluently.
Why Dependency Injection?
Dependency Injection relies on a principle called Inversion of Control. The main idea is that a piece of code that requires some dependencies won’t create them for itself, rather the control over providing these dependencies is deferred to some higher abstraction. These dependencies are typically passed into an object’s initializer. This is the opposite approach — an inverted approach — to the typical cascade of object creation: Object A creating Object B, creating Object C, and so on.
From a practical perspective, the main benefit of Inversion of Control is that code changes remain isolated. A Dependency Injection Container supports the Inversion of Control principal by providing an object that knows how to provide the dependencies for an object. All you need to do is ask the container for the object you need, and voilà… it’s ready!
