Develop - QuickShare

[sameerasw]

This pull request introduces several major improvements to the AirSync macOS project, primarily focused on enhancing file and text sharing via a new Quick Share feature. It adds new package dependencies, refactors drag-and-drop handling for better user experience, and introduces a visually engaging device selection interface. Additionally, it updates the app's initialization and file handling logic to integrate the new Quick Share workflow.

Key changes:

Quick Share Feature Integration

• Refactored the drag-and-drop logic in DropTargetModifier.swift to use a new QuickShareDropDelegate, providing improved handling for both file and text drops, dynamic overlay labels, and support for modifier key detection. The new logic initiates device discovery and launches a transfer UI when files are dropped, or sends text directly if appropriate. [1] [2]
• Added a new RadarView component to visually display nearby devices in a radar-like interface, allowing users to select a target device for sharing.

Dependency Management

• Added new Swift package dependencies: BigInt, ASN1, SwiftECC, and swift-protobuf to the Xcode project configuration and lockfile, enabling cryptographic and protocol support needed for Quick Share. [1] [2] [3] [4] [5] [6] [7] [8] [9]

App Initialization and File Handling

• Updated AppDelegate to initialize QuickShareManager at launch, and refactored file opening and Services menu actions to use the new Quick Share workflow instead of direct WebSocket file sending. This ensures a consistent and modern sharing experience. [1] [2]

Miscellaneous Improvements

• Added a bridging header (AirSync-Bridging-Header.h) for Objective-C/Swift interoperability, currently importing a notification center utility.
• Fixed an incorrect internal import Combine statement in AppState.swift to standard import Combine.
