Window Management

Overview

Use this skill to tailor each SwiftUI window to its job. Start by identifying which scene owns the window (Window, WindowGroup, or a dedicated utility scene), then customize the toolbar/title area, background material, resize and restoration behavior, and initial or zoomed placement.

Prefer scene and window modifiers over ad hoc AppKit bridges when SwiftUI offers the behavior directly. Keep each window purpose-built: a main browser window, an About window, and a media player window usually want different chrome, resizability, restoration, and placement rules.

These APIs are macOS 15+ SwiftUI window/scene customizations. For older deployment targets, expect to use more AppKit bridging or availability guards.
