WWDC26: Sessions Worth Your Time

WWDC26 has kicked off with its usual excitement and chaos of news, promises and updates. Over 100 sessions dropped last night, and it can feel a little overwhelming to choose from. We’ve asked members of the Kodeco team to share the sessions they’re heading to first.

Start Here

Firstly, if you haven’t already: catch up on the WWDC26 Keynote and the Platforms State of the Union first — they’re the best overview of everything announced before you dive into individual sessions.

If you only watch a few sessions, make them these “What’s new” videos. Several of our community members pointed to these without a second thought, which should make them obvious picks to watch first.

What’s new in Xcode 27 — The essentials: what’s changed in your daily workflow, including coding agents now living inside the editor, personalisation options and the new Device Hub.

What’s new in SwiftUI — A broad overview of this year’s additions. A good watch regardless of what you’re building.

What’s new in Swift — Worth a watch for the language updates.

Significant AI Updates

This is where the bulk of WWDC26’s energy is, and it’s genuinely a lot to take in. One of our community members pointed out that nearly 70% of the keynote was on AI updates, all long overdue.

What’s new in the Foundation Models framework — The broadest overview and a great place to start to find out what AI can do for your apps.

Meet Core AI — Apple’s new framework for deploying your own AI models on-device, covering the full pipeline from conversion to Swift integration.
Pair it with Integrate on-device AI models into your app using Core AI for the practical walkthrough.

Build agentic app experiences with the Foundation Models framework — A more advanced session focused on orchestrating multiple agents and managing context across them.

Discover new capabilities in the App Intents framework — Siri has been significantly overhauled this year, now called Siri AI and powered by Gemini. App Intents is how your app talks to it.

Personal Picks

The above is a solid overview of what has changed and how the new frameworks are intended to work. Whether they hold up once out of beta — Genmoji implementation, we’re looking at you — we won’t know until more developers have had a chance to play around with the new code.

Susannah, who many of you know from our podcast, has worked years in app marketing, and her personal pick is Enhance your presence on the App Store — one that’s easy to overlook if you’re not thinking about distribution, but well worth your time if you are. Roberto, who you’ll find at the heart of our Discord community (and who is so dedicated that he tuned in mid cross-atlantic flight), flagged an under-the-radar but impressive addition: support for Pixar’s OpenUSD via the new USDKit framework. It might not be of practical use for many, but if you’re looking for something a little different, check out Discover USDKit and what’s new in OpenUSD.

Sam, Kodeco’s CTO was also mid-flight when the sessions were announced. He’d like to complain about some of the presentation styles, but we won’t go there here. As he is doing mostly web development these days, he found the What’s new in WebKit for Safari 27 quite interesting.

Mani, one of our community moderators, iOS developer, and bootcamp mentor, came with a long list, but we’ve picked out a few to highlight here. Create UI prototypes using agents in Xcode is a practical look at using Xcode’s coding agents to rapidly explore and iterate on UI ideas before committing to them. And Meet the Music Understanding framework which is a new framework for analysing and working with music in your apps, which feels like it could open up some interesting creative directions.

If you want to hear Mani’s full list of suggestions, or share your thoughts on the sessions you’ve seen, our Discord’s #wwdc2026 channel is live throughout the week, and our team members are always happy to share their thoughts or help you decide what to focus on.

We’ll have more specific articles on WWDC26 coming later in the week, and we’ll be assessing what content needs updating over the next couple of weeks — so keep an eye out. In the meantime, all WWDC26 sessions are free to watch on the Apple Developer app or YouTube.
