Hello, i worked on ionic version 3 app i want to publish it to apple store i build it successfully but when submit it to review the app rejected because

We discovered one or more bugs in your app when reviewed on iPad running iOS 13.7 on Wi-Fi.Your app launches and shows an unresponsive white screen with no other content.

then i start new ionic 3 project and i faced same problem.
I tried to build using cordova ios v6 and v5 but i have the same problem.
i build it using this commands

ionic cordova platform add ios
ionic cordova run ios --prod -l --external --emulator --consolelogs --target="C62C1D15-1BDF-433C-BD72-2D9957C5F0F7"

when i run it on iphone emulator it work well but on ipad give me this issues

@nazeeh Try to run the project directly from XCode, opening the platform folder.

Build before (build, not run) correctly the version for iOS and selected iPad device, then you run such files in the editor.

Before, remember to install the iPad simulator:

try this steps

ionic cordova platform add ios
ionic cordova prepare ios
ionic cordova build ios --prod

then open workspace from project-name/platforms/ios and try to build from Xcode .
If not solved your issue try:

ionic cordova platform rm ios
ionic cordova platform add ios
ionic cordova prepare ios

then open workspace from project-name/platforms/ios and try to build from Xcode .
