Multiplatform Library Development
summary
A practical postmortem on building an early Kotlin library: describes creating multiplatform settings (shared-preferences abstraction) with Android SharedPreferences, Apple UserDefaults, JS localStorage and a JVM Properties fallback, plus an in-memory mock for tests; explains switching from expect/actual to interfaces for testability, implementing key-specific listener semantics to normalize platform differences, publishing artifacts to Bintray, missing CI, Gradle/iOS simulator quirks, and ongoing work for 32-bit iOS and broader samples.
