how to donate app as default camera app

To set your app as the default camera app on the Lock Screen, you can create a "locked camera capture extension" as described in the session "Build a great Lock Screen camera capture experience" from WWDC 2024. Here are the key steps:

1. Create a Locked Camera Capture Extension: This is a new type of app extension that allows your app to be accessed directly from the Lock Screen. It should provide a consistent capture experience similar to your main app.

2. Implement Camera Capture Intent: Introduced in iOS 18, this system intent allows your app or extension to be launched directly into the camera capture experience. You need to include this intent in your widget extension, your app, and your extension targets.

3. Use AV Capture Event Interaction: This is necessary to handle events from the system hardware buttons, allowing users to quickly capture photos or videos even when the device is locked.

4. Privacy and Permissions: Ensure that your extension and application include privacy usage descriptions for the camera, as this signals to the system your intent to use the camera for capturing photos and videos.

5. WidgetKit for Control: Build a custom control using WidgetKit that can launch your capture experience from the Lock Screen.

For more detailed information, you can refer to the session Build a great Lock Screen camera capture experience (14:40) which discusses implementing the camera capture intent and other related features.
