WWDC 2025 First Impressions and What's Next

I’m still trying to take in everything that was announced at WWDC on Monday. With 120 sessions available, I’ve already bookmarked 50 that I want to go through over the next couple of weeks. I’ll begin with the “What’s New in…” sessions and go from there.

Each week, I’ll share what I’ve learned, highlight what seems most valuable, and let you know which topics I plan to cover in upcoming videos.

To test the latest features, I’ve installed macOS 26 on my MacBook Air. This will allow me to run Xcode 26 and explore the new ChatGPT integration. I’ve already watched the “What’s New in Xcode” session, and it looks like it will significantly change how we create apps. I’ll share more about that next week.

I’ve also installed iPadOS 26 on my M2 iPad Air, and the new window management features really stand out. I can now run multiple apps in resizable windows, which brings a very Mac-like experience to the iPad.

On my iPhone 11 Pro, I’ve installed iOS 26. Since this device doesn’t support Apple Intelligence, I’ll be relying on my iPad to test those features. Everything has been fairly stable so far, but since this is only Beta 1, I’m holding off on installing it on my primary devices.

In addition to the major announcements, there are lots of smaller improvements to things like SwiftData and SF Symbols. The most noticeable change, however, is the new Liquid Glass UI. It’s a dramatic visual shift and quite beautiful, but some elements are harder to read. I’ll be compiling several of my apps to see how they look and determine what adjustments might be needed.

If you watched the Keynote or the State of the Union and found something you’re particularly excited about, I’d love to hear from you. Feel free to reach out by email or through any of the social platforms I’m on. There is so much to explore, and I want to focus on the features that will bring the most value to the community.

SwiftUI Charts Mastery

It’s no secret that I’m a huge fan of Mark Moeykens (Big Mountain Studio) and the incredible books he creates. His first book, SwiftUI Views Mastery, was a huge success, and honestly, it belongs in every SwiftUI developer’s library.

Since then, Mark has gone on to publish many more books that have deepened my understanding of various Swift and SwiftUI frameworks. I personally struggled with Core Data and Combine, but Mark’s clear and approachable teaching style really resonated with me. His books on those topics made a huge difference in my ability to grasp and apply them in real-world projects. So when he released SwiftData Mastery in SwiftUI, it was an instant buy.

And now, he’s done it again with his newest release: Swift Charts Mastery. This was another immediate purchase for me.

If you’re looking to unlock the full potential of data visualization in your SwiftUI apps, Swift Charts Mastery is the guide you need. It’s packed with practical, real-world examples and tons of customization options. You’ll learn how to turn your app’s data into compelling, interactive charts that both inform and engage your users.

Just a quick note: I’m an affiliate of Big Mountain Studio, so if you use any of the links in this section to purchase a book, I do receive a small commission. That said, feel free to visit the site and purchase directly—that’s what I usually do myself. The books are all reasonably priced and are, bar none, some of the best reference materials available for Swift and SwiftUI developers.

What is Coming?

Next week, I’ll continue with Part 2 of my three-part series on creating an SF Symbols Picker Swift Package. In last week’s video, we explored where to find the list of SF Symbols, their categories, and associated search terms, and how to decode the property lists that contain this data.

Even if you didn’t catch the first video, you’ll still be able to follow along. I’ll provide a link to the necessary data in the description, so you can jump right into building a fully functional and reusable SF Symbols picker. Then, in the final part of the series the following week, we’ll convert it into a Swift Package. But rest assured—the version you build next week will be complete and ready to use in your own projects right away.
