This pull request adds a new Widget Extension target to the Xcode project, enabling development of a macOS widget for AirSync. The changes introduce the new AirSyncWidgetExtension target, configure its build settings, entitlements, and dependencies, and add a shared app group for secure data sharing between the main app and the widget. Additionally, a new Xcode scheme is created for building and running the widget extension.

Widget Extension Integration:

• Added the AirSyncWidgetExtension target to the Xcode project, including its build phases, dependencies, and associated product (AirSyncWidgetExtension.appex). [1] [2]
• Created a new Xcode scheme AirSyncWidgetExtension.xcscheme to support building, running, and debugging the widget extension in the simulator.

Build Settings and Entitlements:

• Added and configured AirSyncWidgetExtension.entitlements and updated the main app's entitlements (AirSync.entitlements) to include the shared app group group.sameerasw.airsync-mac.widget. [1] [2] [3] [4] [5]
• Set up build configurations for the new target, including code signing, deployment target, Swift version, and other relevant settings. [1] [2]

Framework and Resource Management:

• Linked the necessary system frameworks (WidgetKit.framework and SwiftUI.framework) to the widget extension target. [1] [2]
• Configured resource and source groups for the widget extension within the project structure. [1] [2] [3] [4]

Project Structure and Dependency:

• Established a target dependency from the main app to the widget extension, ensuring proper build order and embedding of the extension. [1] [2]

These changes lay the groundwork for developing and shipping a macOS widget alongside the main AirSync app.
