About this session

Discover the inner workings of lazy stacks in SwiftUI. We'll explore how LazyVStack and LazyHStack estimate sizes, lazily load subviews, and prefetch content to deliver smooth scrolling experiences. We'll also cover advanced performance optimizations, state management best practices, and tips for precise programmatic scrolling. To get the most out of this session, we recommend basic familiarity with SwiftUI layout using stacks.
