Which iOS versions does this skill cover?

It covers SwiftUI layout features and container components from iOS 14 all the way through the latest performance improvements in iOS 26.

When should I use Lazy containers versus standard Stacks?

The skill provides a performance guide recommending standard Stacks for small sets (1-20 items) and Lazy stacks or Lists for larger datasets (20+ items) to optimize memory usage.

How does this help with grid layouts?

It provides detailed usage patterns for both static Grids (iOS 16+) and flexible LazyVGrid/LazyHGrid, including configurations for adaptive and fixed GridItems.

Does it include information on scroll animations?
