How do I to add a document scanner into my app?

To add a document scanner to your app, you can leverage the capabilities discussed in the WWDC sessions. Here are some steps and relevant information to help you get started:

1. Use the Camera for Capturing Documents:

   • You can create a camera capture experience using the new framework introduced in iOS 18, which allows you to build a capture experience that runs from the lock screen. This is detailed in the session Build a great Lock Screen camera capture experience.

2. Implementing the Capture Extension:

   • Define your extension to conform to the locked camera capture extension. This will allow you to create a consistent capture experience that can be accessed from the lock screen. More details can be found in the session Build a great Lock Screen camera capture experience.

3. Handling Permissions:

   • Ensure that your extension and application include privacy usage descriptions for the camera. This is necessary for the system to display the description explaining why your app needs to use the camera. This is discussed in the session Build a great Lock Screen camera capture experience.

4. Working with Captured Content:

   • After capturing the document, you can either add the photo and video assets directly to the user's photo library or store the data in a provided directory on the file system. For more in-depth interactions, such as sharing or applying filters, you can transition from the extension to the parent application. This is covered in the session Build a great Lock Screen camera capture experience.

5. Using Vision APIs for Document Scanning:

   • Although not explicitly mentioned in the provided context, Apple’s Vision framework can be used to detect and recognize text in images, which is a common requirement for document scanning. You can integrate Vision APIs to enhance your document scanning capabilities.

For a more detailed guide, you can refer to the chapters in the session Build a great Lock Screen camera capture experience, especially the sections on the lifecycle of a capture extension and working with captures in your app.
