How can I build a simple photo album app

To build a simple photo album app, you can leverage several concepts and tools discussed in various WWDC sessions. Here’s a step-by-step guide based on the provided context:

1. Model Your Data:

   • Define your fundamental model types, such as assets and albums. An asset can represent a photo or video in your library with properties like title and creation date.
   • Example from the session Bring your app to Siri: "My app has two fundamental model types, assets and albums. Let me show you how asset is defined. Asset is an object that represents a photo or video in my library."

2. Capture Photos:

   • Use the new Locked Camera Capture framework introduced in iOS 18 to capture photos directly from the lock screen.
   • Example from the session Build a great Lock Screen camera capture experience: "New in iOS 18, your camera experience can be made available to people right from their lock screen on both iPhone and iPad."

3. Handle Captured Content:

   • Store captured photos and videos in the photo library or a provided directory on the file system.
   • Example from the session Build a great Lock Screen camera capture experience: "A capture extension can either directly add photo and video assets to a person's photo library, or the extension can store any data it needs to represent a capture to a provided directory on the file system."

4. Integrate with Siri:

   • Enhance your app by integrating with Siri to perform actions like viewing, favoriting, and sharing photos.
   • Example from the session Bring your app to Siri: "I can click on a photo to view it full screen. I can also click on this menu at the top to perform actions like favorite and share."

5. Use Quick Look for Previews:

   • Utilize Quick Look to preview photos and videos within your app, allowing for convenient editing options.
   • Example from the session What’s new in Quick Look for visionOS: "Quicklix supports these convenient edit options by default, and any edits made are automatically written back to the original file."

6. Enhance User Experience:

   • Consider adding features like image playground for creating fun avatars or editing images.
   • Example from the session Platforms State of the Union: "I want to use the new image playground API to let users add fun avatar pictures to their user profiles."
