Lists & Grids SwiftUI reference

Lazy stacks create children only as they scroll into view and support section headers that pin to the edge while their section passes.

LazyVGrid scrolls vertically and fills columns described by GridItem: fixed, flexible, or adaptive — the three words that define every grid design.

LazyHGrid scrolls horizontally and fills rows defined by GridItem heights — the sideways twin of LazyVGrid for shelf and timetable layouts.

List renders platform-native rows from data. ForEach adds onDelete and onMove editing, and a selection binding turns rows tappable with single or multi-select.

Restyle List without leaving it: listRowBackground, listRowInsets, separator visibility and tint, listRowSpacing, listSectionSpacing, and scrollContentBackground.

swipeActions adds leading and trailing buttons with full-swipe control, refreshable wires async pull-to-refresh, and badge annotates rows with counts.

OutlineGroup and List(children:) render tree-shaped data with disclosure triangles — file browsers, org charts, and nested categories without manual recursion.

Table presents multi-column data with selectable rows and sortable headers on Mac and iPad, collapsing gracefully to its first column on iPhone.

ContentUnavailableView standardizes empty, error, and no-results screens with an icon, title, description, and action buttons — including the built-in search variant.
