This is the SwiftUI reference you actually need when views won't update, navigation breaks, or previews crawl. It covers the full spectrum: debugging state issues, navigation architecture (including deep linking and restoration traps), layout gotchas on iPad, performance patterns for lazy stacks, and gestures. The cross-references are tight, like pointing you to axiom-uikit for UIKit bridging or axiom-design for Liquid Glass patterns. The anti-rationalization table is honest about common dismissals ("simple layout, no need") versus reality ("12 gotchas"). Includes iOS 26 feature coverage and automated auditors for architecture, performance, and navigation. If you're doing any SwiftUI work beyond hello world, this saves you from two-hour debugging sessions by giving you the diagnosis pattern upfront.
