Ionic white screen on IOS startup - ionic-framework

Question

I'm developing an app with Ionic in version 3 but I'm having a problem with the build for IOS, just for IOS.
For several days I researched and did not find a solution to my problem, able to compile the last two versions without problem, but now that I need to release another version, but it is not going.
Only the build for iOS is giving trouble.
The problem
After the build, testing on a real device, the application enters the splashscreen and exits, entering a white screen that does not come out at all.
This occurs only in the build with the --prod flag. When I run in debug mode it 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 to help is welcome. Thanks in advance!

I had a similar issue and nothing seemed to be working.
In the end, I added the browser as a platform.
ionic cordova platform add browser
Then, I tried to run that as production and it was from there, that I was able to diagnose the problem more, because the errors were shown then in the console.
ionic cordova run browser --prod --release
I didn't have much luck with XCode showing me and real errors.

I got a similar issue recently. Are you using ionic SplashScreen plugin? Can you try performing a clean installation after deleting node_modules, platforms and plugins directories.
If it didn't work update your app.component.ts like this.
import { SplashScreen } from '#ionic-native/splash-screen';
export class MyApp {
...
constructor(... public splashScreen: SplashScreen, ...) {
this.initializeApp();
}
initializeApp() {
this.platform.ready().then(() => {
...
setTimeout(() => {
this.splashScreen.hide();
}, 2000);
...
});
}
In your config.xml set this perference.
<preference name="AutoHideSplashScreen" value="false" />
<preference name="SplashShowOnlyFirstTime" value="false" />
<preference name="ShowSplashScreen" value="false" />
<preference name="SplashScreenDelay" value="3000" />
<preference name="ShowSplashScreenSpinner" value="false" />
<preference name="FadeSplashScreen" value="false" />
