在SwiftUI中使用SceneKit时，如何访问SCNSceneRendererDelegate方法？

class SceneDelegate: NSObject, SCNSceneRendererDelegate {
    func renderer(_ renderer: SCNSceneRenderer, updateAtTime time: TimeInterval) {
        // 在这里实现你的逻辑
    }
}

struct ContentView: View {
    let sceneDelegate = SceneDelegate()
    
    var body: some View {
        SCNSceneView().environment(\.scenePhase, .background).onAppear {
            sceneDelegate.renderer(sceneView, updateAtTime: 0)
        }
        .onDisappear {
            sceneDelegate.renderer(sceneView, updateAtTime: 0)
        }
        .onReceive(scenePhasePublisher) { phase in
            switch phase {
            case .active:
                sceneDelegate.renderer(sceneView, updateAtTime: 0)
            case .inactive:
                sceneDelegate.renderer(sceneView, updateAtTime: 0)
            case .background:
                sceneDelegate.renderer(sceneView, updateAtTime: 0)
            @unknown default:
                break
            }
        }
    }
}
