I had the same problem.
我有同样的问题。
I opened the ios project in the platform folder via Xcode, but I forgot that the codebase in the Xcode folder was not up to date and therefore broken.
我通过Xcode打开了平台文件夹中的ios项目，但我忘记了Xcode文件夹中的代码库不是最新的，因此被破坏了。
To get the new code in your Xcode project use the command:
要在 Xcode 项目中获取新代码，请使用以下命令：
ionic cordova prepare ios
If your problem is rooted in the same as mine this should help.
如果您的问题与我的问题根源相同，那么这应该会有所帮助。

I encountered this issue when I tried to run my Ionic 4 app on an iOS device.
当我尝试在 iOS 设备上运行我的 Ionic 4 应用程序时，我遇到了这个问题。
What solved it for me, was running the dev server on all network interfaces using the --addressoption, for example:
为我解决的问题是使用该--address选项在所有网络接口上运行开发服务器，例如：
ionic cordova run ios --address=0.0.0.0 --debug --consolelogs -l
ionic cordova run ios --address=0.0.0.0 --debug --consolelogs -l

I have run the server and simulator and again am trying to update the app on the device.
我已经运行了服务器和模拟器，并再次尝试更新设备上的应用程序。

I stoped my simulator and re builded the app and opened the project.xcodeproj file with Xcode and run it on the device.This worked for me
我停止了我的模拟器并重新构建了应用程序并使用 Xcode 打开了 project.xcodeproj 文件并在设备上运行它。这对我有用

I had this same issue using XCode9.3 and ionic3. Turns out that the issue was caused by missing configurations in "config.xml" needed for WKWebview to function properly. I added the following snippet to my config.xml, before deleting the "platforms/ios" folder and running "ionic cordova build ios --prod" again.
我在使用 XCode9.3 和 ionic3 时遇到了同样的问题。事实证明，该问题是由于 WKWebview 正常运行所需的“config.xml”中缺少配置造成的。在删除“platforms/ios”文件夹并再次运行“ionic cordova build ios --prod”之前，我将以下代码段添加到我的 config.xml 中。
<allow-navigation href="http://localhost:8080/*" />
<feature name="CDVWKWebViewEngine">
<param name="ios-package" value="CDVWKWebViewEngine" />
</feature>
<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />See link herefor a more detailed explanation from the ionic team.
