LazyVGrid SwiftUI Tutorial 2026 — Adaptive, Lazy, Scrollable

A hundred photos. Two columns on iPhone, four on iPad, automatic on rotation, only the visible cells alive. Hand-rolling that with HStacks doesn't work - and Grid renders everything up front.

This video covers LazyVGrid end-to-end: the GridItem column system, the three sizing modes nobody explains well, pinned section headers, and a real Photos-style adaptive grid.

📌 What's covered:
— LazyVGrid + GridItem basics
— GridItem.fixed, .flexible, .adaptive — when to use which
— Spacing and alignment per column vs per grid
— Pinned section headers (sticky headers like Photos)
— Building a real adaptive photo grid that responds to rotation
— LazyHGrid — the horizontal counterpart
