Dependency Injection in Swift: Stop Creating, Start Receiving
Source: donnywals.comintermediate
Dependency Injection means objects receive their dependencies from the outside rather than creating them internally. It's used to give a view model a network client or data source, making it testable.
Dependency Injection (DI) is a pattern where you pass dependencies, like a network client, into an object from the outside rather than letting it create them internally. This decouples components, making them modular and testable. In Swift, this often means a `ViewModel` receives a data provider via its `init` method, ideally depending on a protocol, not a concrete type. This allows swapping in mocks for testing.
