file:///app/tns_modules/tns-core-modules/ui/builder/builder.js:196:56: JS ERROR Error: Building UI from XML. @file:///app/home/home-page.xml:13:5"

Expected: App not to crash and the red label on the device to be shown with the proper text

Reproduce with a project whose XML contains an invalid element such as , then run tns run ios and tns run android. Start at tns-core-modules/ui/builder/builder.js:196 and compare the console error with the expected device behavior; done means the app does not crash and the device shows the proper red error label.
