When your SwiftUI views scroll like molasses or gesture recognizers fight each other, this is the fix. It's the performance chapter from the larger axiom-swiftui suite, covering LazyVStack gotchas, view identity traps, and state optimization patterns that typically solve UI lag in minutes. The parent skill explicitly routes you here before reaching for Instruments, since domain-specific fixes (wrong container type, broken identity, over-rendering) usually beat profiling for speed. If you're fighting choppy scrolling, unresponsive interactions, or preview slowness that persists after disabling auto-refresh, this has the concrete patterns SwiftUI developers actually need.
