This is the issue!, that on my prod build the app do not initialize and when debugging on console it says
file:///var/containers/Bundle/Application/39C211E1-ACD2-4798-96FF-8909F63DB55A/TestApp.app/www/build/main.js.map Failed to load resource: The requested URL was not found on this server.

i know prod builds should not produce map sources and thats why im reporting this case !

Thanks

Hello, thanks for using Ionic! We do not generate source maps in a prod build as they would add to the size of the app and therefore have a negative impact on performance. I am going to close this one as a duplicate of driftyco/ionic-app-scripts#805.

workaround:

package.json:
"ionic_uglifyjs": "./...../uglifyjs.config.js"
add "sourceMapUrl: false" to your uglifyjs.config.js

in node_modules/@ionic/app-scripts/dist/uglifyjs.js line 58
add "sourceMapUrl: uglifyJsConfig.sourceMapUrl"
