Maintain a Swift project's dependency graph with Weaver

Software architecture has a lot to do with making sure the dependency graph is well structured. But in practice, maintaining a clean dependency graph while injecting dependencies in a type safe & runtime safe manner is a lot of repetitive code to write. This problem often leads developers to overuse the singleton pattern, making their code less modular at best, almost untestable at worst. Weaver is a code generation tool which makes it easy to inject dependencies where they are needed while maintaining a safe & clean dependency graph at the same time.

Opinionated Dependency Injection in Swift

Writing dependable code at scale means writing tests, & writing tests means using Dependency Injection. The concept of DI is absurdly simple -- yet DI frameworks often end up being quite complex. At Lyft, we developed a minimalist, opinionated DI solution for our Swift codebase. It provides compile-time safety, decentralized configuration, & a clean syntax. And by having preferences about state & "magic", it remains absurdly simple.
