Can I create a photo app that is responsive for large libraries

Yes, you can create a photo app that is responsive for large libraries. Apple provides several tools and frameworks to help you manage and present large photo libraries efficiently.

1. Photokit: You can use Photokit to programmatically fetch all spatial assets from the user's photo library. By setting spatial media as your PHAssetMediaSubtype when constructing your fetch predicate, you can filter and manage large libraries effectively. Photokit also supports granular levels of photo library access, such as write-only access and limited library support, which can be useful for handling large amounts of data securely (Build compelling spatial photo and video experiences).

2. Quick Look Framework: For presenting spatial content, you can use the preview application API in the Quick Look framework, which supports both photos and videos. This can help in efficiently displaying large libraries of media content (Build compelling spatial photo and video experiences).

3. Capture Extensions: If your app involves capturing new photos and videos, you can use capture extensions to add these assets directly to the user's photo library. This ensures that new content is seamlessly integrated into the existing library (Build a great Lock Screen camera capture experience).

4. Handling Permissions: Photokit is designed to protect private photos and videos, especially when the device is locked. It allows you to manage permissions effectively, ensuring that your app can access the necessary data without compromising user privacy (Build a great Lock Screen camera capture experience).

By leveraging these tools and frameworks, you can create a responsive and efficient photo app that handles large libraries effectively. For more detailed information, you can refer to the sessions mentioned above.
