White Screen after splashscreen in ios

Hello, I got some issues from the app store because my app got White Screen after SplashScreen.
I try to change value SplashScreenDelay but it does not work.

How can I solve it with ionic 4?

Can you please provide a sample app we can inspect?

After I upgrade cordorva-plugin-ionic-webview to version 4 follow the apple feedback ITMS-90338: Non-public API usage and the follow this link

I got this error.
if i downgrade cordova-plugin-ionic-webview to version 2.3.1 it works like normal.

what can i do with it if i downgrade apple will reject it and can not upload to app store if i upgrade it will error with white blank page ?

So you’re better off going through the issue and attempting to fix the 4.x errors.

You could try…

ionic cordova platform rm ios
ionic cordova plugin rm cordova-plugin-ionic-webview
ionic cordova plugin add cordova-plugin-ionic-webview
ionic cordova platform add ios

This will give you a “fresh” base to work off of

Yes,Sir. I worked follow your Suggestion it can upload to App Store but i had problem when they review my app and they rejected.because it still have blank white space.
