Platform Integration

Expose key app actions and data as App Intents so Siri, Shortcuts, Spotlight, widgets, and the system can invoke them.

Apps that sync data, process uploads, or maintain state SHOULD use platform background execution APIs rather than relying on foreground presence.

All significant feature points and views MUST be deep linkable using the platform's native URL/deep link mechanism:

Apps available on multiple devices SHOULD support continuity features so users can start work on one device and resume on another.

Apps SHOULD use the platform notification system for timely, actionable alerts that respect user preferences.

Components and flows SHOULD be scriptable where the platform supports it:

App content SHOULD be discoverable through the platform's system search, enabling users to find content without opening the app.

Apps SHOULD participate in the platform's share and inter-app data exchange mechanisms to integrate with other apps and workflows.

Use AppKit (macOS) and UIKit (iOS) for all UI. Use SwiftUI only where Apple requires it.

Apps with time-sensitive or frequently checked data SHOULD provide widgets and glanceable surfaces on platforms that support them.
