White screen on IOS startup

I'm developing an app with Ionic in Version 3 but I'm having a problem with the build for IOS, only for IOS.

For several days I researched and did not find a solution to my problem, being able to compile the last two versions without problem, but now that I am needing to release another version, it is not going even to PAUU!!

Only build for IOS is giving problem.

A problem

After build testing on a real device, the application enters the splashscreen and exits, entering a white screen that does not exit at all.

This occurs only in the build with the --prod flag. When I squeak in mode debug works perfectly, with livereload and everything else.

Information

In the Xcode console the only thing I see is all startup and when the app is locked on the white screen I see TIC Read Status [10:0x0]: 1:57 and TIC Read Status [11:0x0]: 1:57

Any attempt at help will be welcome. Thank you since now!

On the Ionic page, there is an explanation that informs that one of the causes may be the incorrect installation of the platform.

Https://ionicframework.com/docs/wkwebview /

If this is the problem, the correction guidance is as follows:

  • close Xcode

  • Remove platforms and plugins

    rm -rf platforms

    rm -rf plugins

  • Include the platform again

    ionic cordova platform add ios

  • Make sure that the navigation to localhost is allowed:

    <allow-navigation href="http://localhost:8080/*"/>

  • Make sure the WKWebView is the default:

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

  • Build again

    ionic cordova build ios
