Design Liquid Glass toolbars in the iOS 26 beta from task priority, system placements, accessibility, and measurable behavior instead of stacked transparency.
Use TaskGroup in Python 3.12 and 3.13 to give concurrent work a bounded lifetime, predictable failure propagation, timeouts, and testable cancellation.
Understand the roles of WebView and WebPage in the iOS 26 beta, then design observable navigation, controlled links, and a gradual compatibility boundary.
Use the WWDC25 and Xcode 26 beta guidance to understand Liquid Glass hierarchy, availability, accessibility, and a reversible migration strategy.
Audit SwiftUI semantics, reading order, Dynamic Type, touch targets, contrast, and reduced motion as one complete user workflow.
