DAT SDK Conventions (iOS)

Architecture

The public SDK is organized into these modules:

• MWDATCore: Device discovery, registration, permissions, device selectors, DeviceSession
• MWDATCamera: Camera, Stream, VideoFrame, photo capture
• MWDATDisplay: Display capability, display UI components, icons, images, buttons, video
• MWDATMockDevice: MockDeviceKit for testing without hardware
• MWDATMockDeviceTestClient: MockDeviceTestClient for driving MockDeviceKit over HTTP from a UI-test process

Swift Patterns

• Use async/await for all SDK operations — the SDK is fully async
• Use AsyncSequence / publisher .listen {} for observing streams
• Annotate UI-updating code with @MainActor
• Never block the main thread with frame processing
• Handle errors with do/catch — the SDK throws typed errors
