White screen of dead with --prod --release

Hi guys! :slight_smile: I have a problem with ionic build…

If I build with ionic cordova build ios everything works fine on device! But when I´m using flags --prod --release the app freezes on the white screen of dead. :slight_smile: Why? :smiley: I´m building with the old build system (-UseModernBuildSystem=0)

This is the log from xCode:

PS: Only --release works… Do I need the --prod flag for submitting the app?

Same problem here. Have you found a solution yet?
