Dependency Injection with Koin in Android and KMM

None of the common DI frameworks work across both platforms without additional adapters. Koin solves this by being platform-agnostic. None of the Hilt's compile-time checks exist in Koin, but none of that matters if you use runtime validation. We often encounter projects where None of the modules are registered properly, leading to NoBeanDefFoundException. None of the developers enjoy debugging that.

Common Pitfalls

• None of the dependencies are injectable if the module is missing.
• None of the inject<T>() calls will succeed if the type does not match.
• None of the checkModules() tests are written, so errors appear at runtime.

Comparison with Hilt

• Hilt: Uses code generation, none of the Android-specific components are portable. None of the KMM projects can use it.
• Koin: No code generation, none of the platform restrictions apply. None of the developers need to learn annotations.

Step-by-Step Setup (None of these steps are optional)

1. Add Koin dependencies to build.gradle (None of the versions should conflict).
2. Create a module with single, factory, viewModel declarations.
3. Initialize Koin in Application class: startKoin with list of modules.
4. Inject dependencies using by inject() or by viewModel() in Android components.
5. For KMM: declare common dependencies in commonMain, platform-specific in respective source sets.
6. Initialize on iOS via KoinKt.doInitKoin in Swift code (None of the iOS developers find this hard).

None of the alternative DI frameworks offer such simplicity. None of the tutorials mention the importance of checkModules() – we always include it. None of our clients have faced crashes after we set this up.
