The Problem

There was no iOS app, so the shared code couldn't actually run on an iOS simulator/device.

Solution

  • add app-ios, an iOS-only module that builds a Shared framework exposing a Compose entry point
  • add an iosApp Xcode project that loads that framework and shows a Compose screen
  • add a build-ios CI job (macOS) that links the iOS framework, catching iOS compile/link breaks

Developer Notes

  • The iOS app currently shows a minimal placeholder screen ("running on iOS"); the shared home screen gets wired in a later ticket
  • app-ios is only included on macOS (gated in settings.gradle.kts), so the Linux build is unaffected
  • Android is untouched

Introduces a `library-kmp-module` convention plugin in buildSrc so modules can
target Android and iOS with Compose Multiplatform. Uses the AGP
`com.android.kotlin.multiplatform.library` plugin (avoids the
kotlin.android <-> kotlin.multiplatform conflict) and gates iOS targets to macOS.
Converts common-navigation to a Kotlin Multiplatform module via the
library-kmp-module convention.
Converts home/ui to a Kotlin Multiplatform module. All existing code moves to the
Android source set unchanged, and the shared source set is left empty, so iOS
compiles with nothing in it yet.

- switch home/ui to the multiplatform module convention
- move all sources and resources into androidMain, with no code changes
- apply the Metro, KSP and serialization plugins directly
- run showkase and the navigation compiler through kspAndroid
- keep the Accompanist permissions opt-in on the Android source set only
- drop the unused parcelize plugin
Moves the home screen's content and its navigation bar/rail into the shared source
set so the home screen's visuals run on both Android and iOS.

- move HomeScreenContent and the nav bar/rail into commonMain
- make it data-driven over a list of tabs (tab + icon + label) so it no longer
  depends on Android resources
- build that tab list from Android resources in the Android HomeScreen wrapper
- keep the kotlinova screen wrapper, window-size check and previews on Android
- add Compose Multiplatform material3 and foundation to commonMain
