iOS
Note
iOS builds require macOS. Apple silicon is the default supported environment for Gemstone builds.
cd ios
just bootstrap
just spm-resolve
just build-for-testing
just bootstrap also creates the local Gemstone UniFFI Swift/header sources that SwiftPM needs for package resolution. Xcode builds the Gemstone Rust static library automatically after that. Intel Macs are not supported for iOS Gemstone builds.
Android
cd android
just bootstrap
just build-test
Developer Shortcuts
The repo root exposes monorepo commands plus module access to each platform:
just build
just generate
just localize
just bump patch
just ios bootstrap
just ios build
just ios build-for-testing
just ios test-without-building
just android bootstrap
just android build
just android build-test

Platform-specific commands remain available through the ios and android just modules.
