Welcome to day four of WWDC. We hope you’re rested and ready to learn more about the latest Apple technologies and frameworks, because we’ve got a lot to share with you.

Even more machine learning

Start your Thursday off with a little movement and discover how Apple engineers built the Action & Vision app using Create ML and the Vision framework. And that’s not all in the realm of machine learning: Check out how you can train models in minutes that make it easy to bring creative visual features to your app, or explore how you can leverage the Natural Language framework to better analyze and understand text.

Swift deep dive

Take your understanding of Swift to the next level. Find out how Swift uses type inference to help you write clean, concise code without compromising type safety. Get to know Swift Numerics, a new Swift package for computational mathematics. And discover what exactly makes code “unsafe” as we take a look at the programming language’s safety precautions — and when you might need to reach for unsafe operations.
