SwiftUI

Build and review modern SwiftUI as one integrated discipline: platform design, view architecture, data flow, concurrency, navigation, accessibility, performance, and testing. macOS 26 and iOS 26 are the primary targets, so start from the system’s Liquid Glass design and native SwiftUI APIs. Do not recreate Liquid Glass with blur, opacity, gradients, or custom overlays.

Standard SwiftUI components, navigation, toolbars, tab bars, menus, sheets, and controls already adopt the current system appearance. Start by using those components as intended; add custom glass only when a custom functional control needs it.
