Layout Fundamentals

Standard Stacks

Use VStack, HStack, and ZStack for small, fixed-size content. They render all children immediately.

VStack(alignment: .leading) {
    Text(title).font(.headline)
    Text(subtitle).font(.subheadline).foregroundStyle(.secondary)
}

Lazy Stacks

Use LazyVStack and LazyHStack inside ScrollView for large or dynamic collections. They create child views on demand as they scroll into view.

ScrollView {
    LazyVStack {
        ForEach(items) { item in
            ItemRow(item: item)
        }
