SwiftUI : WKWebView有没有办法在WKWebView加载完成后调用函数？

import SwiftUI
import WebKit

struct ContentView: View {
    var body: some View {
        WebView(url: "https://www.example.com")
    }
}

struct WebView: UIViewRepresentable {
    let url: String
    
    func makeUIView(context: Context) -> WKWebView {
        let webView = WKWebView()
        webView.navigationDelegate = context.coordinator
        webView.load(URLRequest(url: URL(string: url)!))
        return webView
    }
    
    func updateUIView(_ uiView: WKWebView, context: Context) {
        // 更新视图
    }
    
    func makeCoordinator() -> Coordinator {
        Coordinator(self)
    }
    
    class Coordinator: NSObject, WKNavigationDelegate {
        let parent: WebView
        
        init(_ parent: WebView) {
            self.parent = parent
        }
        
        func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
            // 在WKWebView加载完成后调用函数
            parent.webViewDidFinishLoading()
        }
    }
    
    func webViewDidFinishLoading() {
        // 在加载完成后执行的函数
        print("WebView加载完成")
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
