Using a Dependency Injection Container
As already mentioned, most people confuse the Dependency Injection pattern with the use of the DI Container. This is mainly true in other languages, such as Java, where a Framework, such as Spring, has been ubiquitous for a while. In the Swift ecosystem, DI Containers are less common, but there are a few, and it's worth having a basic idea of how they work since it could be useful in particular projects, such as an enterprise one with several developers.
Why you should use a DI Container
We have seen that Dependency Injection can be achieved by implementing the right constructor and binding the dependencies at the start of the app, without using a third-party framework.
However, sometimes using one of these containers could help to ensure a uniform architecture, which is helpful when you have a really big development team. If the container you choose is used in several apps, you can be sure that it's often more robust than an internally-developed one....
