2024 WWDC what are some LLM or text processing related AI developer API apple provided?

At the 2024 WWDC, Apple introduced several AI developer APIs related to large language models (LLMs) and text processing. Here are some highlights:

1. Apple Intelligence: This is a personal intelligence system that integrates powerful generative models into iOS, iPadOS, and macOS. It provides new capabilities for understanding and generating language and images, helping users take actions with awareness of personal context. This system is built with privacy in mind and is deeply integrated into system features and apps.

2. Writing Tools: These tools help users rewrite, proofread, and summarize text. They are integrated into standard UI frameworks, allowing apps to automatically benefit from these capabilities. Developers can customize app behavior using the new textview Delegate API.

3. Translation API: A new framework for language translation allows apps to perform direct language-to-language translation with a simple UI. This API can translate any text and display the output in any UI, supporting batch requests for efficient translation.

4. CreateML: This tool allows developers to customize models with their own data. It includes a new object tracking template for training reference objects to anchor spatial experiences.

5. ML-powered APIs: These APIs offer capabilities for natural language processing, sound analysis, speech understanding, and vision intelligence. Developers can extend these frameworks by using CreateML to train models with additional data.
