dynamic UITextView

In the WWDC 2024 session titled "Get started with Writing Tools," several new features and APIs related to UITextView were introduced. These include:

1. New Delegate Methods and Properties: New delegate methods for UITextView and NSTextView have been introduced to manage writing tools. These methods help in preparing app states when writing tools are active, such as pausing syncing or avoiding accidental editing. Additionally, a new property isWritingToolsActive is available to check if a writing tool session is active.

2. Handling Long Text: When dealing with long text, rewritten text may be delivered in chunks, and animations are applied to indicate processing. Users can switch between original and rewritten text for proofreading, and changes are automatically applied to the text field.

3. Customizing Writing Tools Behavior: You can customize the behavior of writing tools using new text input traits APIs. Options are available to specify if your UITextView supports rich text or tables.

4. Custom Text Views: For custom text views, adopting UITextInteraction or UITextSelectionDisplayInteraction can provide a basic writing tools experience. The UITextInput protocol is used under the hood for text interactions.

5. Protecting Ranges: New delegate methods allow you to specify text ranges that writing tools should ignore, such as code blocks or quoted content.

For more detailed information, you can refer to the session Get started with Writing Tools (07:03) which covers controlling behavior, and Custom text views (09:03) for custom text view implementations.
