Swinject

Leverages Swift's generics and first-class functions for a fluent, compile-time checked interface, ensuring dependencies are defined naturally within Swift code, as emphasized in the README's pure Swift type support.

Offers multiple object scopes like singleton, graph, and hierarchical, allowing precise control over dependency instantiation and sharing, which is essential for complex architectures.

Handles circular dependencies between components seamlessly, a feature documented in the README that prevents common pitfalls in interconnected code designs.

Supports container hierarchies and assembly-based registration, enabling developers to break large apps into loosely-coupled, testable modules as highlighted in the modular components feature.
