### AI overview

A guide to planning and watching WWDC 2026 sessions, highlighting platform themes and selected updates in Swift, SwiftUI, Xcode, WebAssembly, gRPC, and MLX.

### Source excerpt

My WWDC 2026 viewing guide to help you plan the sessions you want to watch. Where Do I Start? The two big themes for the year are again Liquid Glass and Apple Intelligence. Start by watching the Platforms State of the Union (SOTU) for a summary of what's new this year. If you only have five minutes try the SOTU recap. You don't have to learn everything new today! There are over 100 sessions and a lot of new stuff to learn. You may feel like you're getting left behind. Don't let it overwhelm you. You've got time. Don't burn yourself out trying to keep up. Watching The Sessions I watch the videos using the Apple Developer app. It's available on macOS and iOS. The video player supports from 0.5x to 2x playback, most videos have transcripts and summaries, and allow copying of the onscreen sample code. You can also watch on YouTube. There are a lot of sessions, but many are short (15-20 minutes). There's no padding and Apple's engineers get to the point quickly. Swift Swift 6.4 is here with some quality of life improvements: What's new in Swift Condense long @available attributes with anyAppleOS, @diagnose to control compiler deprecation warnings. Double-colon module selector. Standard Library task cancellation shield, dictionary mapKeyedValues, new FilePath type. XCTest interop with Swift Testing. Subprocess 1.0. New ProgressManager. @C attribute for Swift-C interop. Compile to WebAssembly. New @inline(always) and @specialized attributes. Iterable protocol for noncopyable elements. Build real-time apps and services with gRPC and Swift gRPC Swift package to generate and deploy network code for remote procedure call services. Explore numerical computing in Swift with MLX NumPy-like API. Examples of computing the Mandlebrot set, heat distribution, and curve fitting. SwiftUI Liquid Glass changes and some welcome improvements: What's new in SwiftUI Liquid Glass is now mandatory. Minimal menu icons by default. Resize live previews in Xcode. Prominent tab role.
