SwiftUI visionOS — padding3D and Multiple Windows From Scratch

Two core visionOS concepts. One cohesive app. Built from scratch. We're building a solar system app that uses .padding3D to push orbital rings into genuine 3D space, and openWindow(value:) to launch individual planet detail panels as independent floating windows. Drag the depth slider and orbit the camera. Watch flat concentric circles become a spatial tunnel. Tap a planet - it appears in your room as its own frameless window. That's visionOS. ⭐ GitHub Repo: https://github.com/NDCSwift/visionos-solar-system 📌 This is Video 2 of the visionOS series: → Video 1: Getting Started → https://youtu.be/ggm_B1CCz8k → Video 2: Depth & Multiple Windows (this video) → Video 3: Volumes & ImmersiveSpace → coming soon Based on Apple's official visionOS beginner tutorials: → Add depth to your app → Present common controls in an ornament ⏱️ Timestamps: 00:00 — What we're building + the two concepts 01:05 — New project setup 01:40 — Planet model — Hashable + Codable explained 05:56 — OrbitalRingsView — ZStack + ForEach + padding3D 12:02 — The depth reveal 12:55 — ContentView + ornament with Grid controls 20:08 — Planet dots on the rings 23:20 — Testing Rings and Planets in Simulator 24:16 — openWindow(id:) vs openWindow(value:) — which to use 24:55 — WindowGroup(for: Planet.self) in the App struct 26:34 — .windowStyle(.plain) + defaultWindowPlacement 27:50 — PlanetDetailView + dismissWindow 31:36 — Full demo 33:38 — What's next: Volumes + ImmersiveSpace 📌 Key APIs: — .padding3D(.back, depth) — real Z-axis depth in a flat window — Grid + GridRow — aligned multi-row controls — ColorPicker — live color updates — .windowResizability(.contentSize) — .ornament(attachmentAnchor: .scene(.bottom)) — .glassBackgroundEffect() — Planet: Hashable, Codable — required by openWindow(value:) — openWindow(id:) — singleton window, no payload — openWindow(value: planet) — typed window, one per unique Hashable value — WindowGroup(for: Planet.self) { $planet in } defaultValue: { } — .windowStyle(.plain) — frameless floating window — @Environment(\.dismissWindow) #visionOS #SwiftUI #iOSDevelopment #VisionPro #SpatialComputing
