我刚刚运行tns run ios --emulator，我得到这个：

我不知道如何调试它。它在Android上构建得很好。这是我的包.json：

labelColor是 iOS 13 引入的新属性。您需要 XCode 11 才能为 iOS 13.x 及更高版本构建。也就是说，其中一个插件正在腌制一个名为MBProgressHUD的pod。该容器使用的是最新的 iOS API。但是您的构建失败很可能是因为它是使用 XCode 10.x 或更低版本构建的。要解决此问题，请尝试使用 XCode 11 和最新tns-ios(6.3.x 及更高版本(+ 最新tns-core-modules进行构建。
