我创建了一个可成功部署到 Android 的 Ionic 4 应用程序。它以前在部署到 iOS 时遇到问题，现在开始工作，它不会在 xcode 中再次部署到 iOS 并显示以下错误:

我在 StackOverflow 上浏览过类似的错误消息，但他们并没有真正提供针对此问题的任何解决方案。

我无法部署到模拟器或设备。

我的 appComponent 很简单:

  initializeApp() {
    firebase.initializeApp(firebaseConfig);

    this.platform.ready().then(() => {
        const unsubscribe = firebase.auth().onAuthStateChanged( user => {
          if (!user) {
            this.router.navigateByUrl('login');
            unsubscribe();
          } else {
            this.router.navigateByUrl('tabs');
            unsubscribe();
          }
        });
      this.statusBar.styleDefault();
      this.splashScreen.hide();
    });
  }

我通过cordova插件添加cordova-plugin-ionic-webview@latest解决了这个问题
