I'm looking for a method or notification to detect window resizing. While I found didResizeNotification for macOS, it's not available in visionPro

Hi, you can use the GeometryReader3D.

If you need the size of the window in meters, you can convert it using PhysicalMetricsConverter

    @Environment(\.physicalMetrics) private var metricsConverter: PhysicalMetricsConverter

    var body: some View {
        GeometryReader3D { proxy in
            let _ = print(proxy.size, metricsConverter.convert(proxy.size, to: .meters))

            RealityView { content, attachments in
                ...
