This covers the modern SwiftUI navigation APIs you actually need: NavigationStack with type-safe routing, NavigationSplitView for iPad layouts, sheet presentation with proper dismiss handling, and TabView architecture with per-tab navigation stacks. The router pattern section is especially useful if you're tired of prop-drilling navigation state through your view hierarchy. It includes iOS 26 additions like search tabs and tab bar minimization, plus practical deep linking setup with universal links and custom URL schemes. The common mistakes section will save you from fighting SwiftUI's navigation quirks, and the manual HStack split pattern is there for when NavigationSplitView doesn't fit your layout needs.
