ionic 5 iOS应用程序停留在启动屏幕上，没有错误日志

我正在尝试构建基于cordova iOS 6.1.0和iOS 13.6的ionic iOS移动应用程序。我的应用程序在启动屏幕上卡住了，下面是XCode日志。我被困在这个问题上好几天了，仍然没有运气。有人能解决这个问题吗

最后，在尝试了这么多方法之后，我终于解决了这个问题

我已通过对我的项目目录运行以下命令解决了此问题：

npm安装

sudo gem安装cocoapods

pod回购更新

爱奥尼亚科尔多瓦平台添加ios@5.1.0

cordova插件更新cordova插件-webview@latest

然后，我将以下内容添加到ios平台下的config.xml中

<feature name="CDVWKWebViewEngine">
<param name="ios-package" value="CDVWKWebViewEngine" />
</feature>
<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />

不要添加

并再次在项目目录中，

爱奥尼亚科尔多瓦准备ios

cordova构建ios
