SwiftUI and UIKit UI conventions for Home Assistant iOS. Use when building views, choosing SwiftUI vs UIKit, bridging with embeddedInHostingController(), building reusable components in the HADesignSystem package, or following the one-struct-per-file, inline-body, and #Preview rules.
Home Assistant iOS project layout, build setup, and the "World" dependency-injection pattern. Use when starting work in the repo, deciding where code lives across targets (App, Shared, Watch, CarPlay, Extensions), accessing dependencies through the global `Current`, or setting up dependencies and code signing.
Swift code style, linting, logging, assets, and idioms for Home Assistant iOS. Use when writing or formatting Swift, running SwiftFormat/SwiftLint, referencing SF Symbols or Material Design icons, logging, or using the with() helper.
Asynchronous code and server networking conventions. Use when writing async/await, Tasks, actors, or Combine, deciding whether to touch PromiseKit, annotating view models with @MainActor, or calling the Home Assistant server via HAKit.
Localization via SwiftGen-generated L10n accessors and the en.lproj .strings files. Use when adding or changing user-facing strings, working with the L10n/CoreStrings/FrontendStrings tables, or dealing with Lokalise-managed translations.
The cross-platform MagicItem action model shared by Widgets, Watch, CarPlay, and App Shortcuts. Use when adding or changing item types or action overrides, or touching anything that persists MagicItem via Codable.

The project uses two database layers:
GRDB.swift): newer layer, accessed via Current.database(). Used for Watch config, CarPlay config, widget config, entity registry, panels, etc. When adding a new persistent model, prefer GRDB: implement DatabaseTableProtocol (defines tableName, definedColumns, and createIfNeeded) and register it in DatabaseQueue.tables() in GRDB+Initialization.swift. The protocol's migrateColumns helper auto-handles additive migrations.RealmSwift): legacy layer, used for older models (actions, zones, sensors, etc.). Access via Current.realm().
