We have Hackathon in Expedia. Want to use something new. What would you recommend?

For your hackathon at Expedia, I recommend exploring the "Foundation Models framework" introduced by Apple. This framework allows you to integrate on-device AI capabilities into your app, which could be particularly useful for creating innovative travel-related features. For example, you could build an app that generates travel itineraries or suggests points of interest using AI. This framework is designed to be easy to use and runs entirely on-device, ensuring user privacy.

You can start by checking out the session titled "Code-along: Bring on-device AI to your app using the Foundation Models framework" from WWDC 2025. This session provides a step-by-step guide on how to use the framework to create an app that plans trips, which could be directly applicable to your hackathon project. The session covers topics like prompt engineering and tool calling, which are essential for leveraging AI in your app.

For more details, you can explore the session chapters:

• Introduction
• Prompt engineering
• Tool calling

This could be a great opportunity to experiment with new technology and create something unique for your hackathon.
