Koin vs. Kotlin-inject
summary
Comparison of Koin and Kotlin‑inject for a Kotlin Multiplatform library integrated into an existing app serving ~40M users shows Koin wins here because its readable DSL, larger community and gentler learning curve make onboarding iOS and junior devs easier, while Kotlin‑inject provides compile-time safety and no runtime overhead plus a neat function injection trick for Compose. Koin’s downside is weaker compile checks for parameterized (assisted) injection — a value‑class→String mismatch caused a runtime crash during migration — but overall the Koin setup works better for this team.
