iOS Code Review Issue #81 covers three main topics from the post-WWDC26 period. First, SwiftUI's new toolbar APIs introduce real overflow and priority logic via visibilityPriority, ToolbarOverflowMenu, topBarPinnedTrailing, and toolbarMinimizeBehavior, solving the long-standing problem of toolbars breaking on smaller screens.

Quick hits include App Store ecosystem hitting $1.4 trillion in 2025, new App Store options in Brazil, Texas age assurance requirements, and Apple's Game Porting Toolkit 4 with Steam Asset Converter.
