Can't lunch my application in the simulator. it launches blank simulator

Ionic Framework ionic-v3
1

I am able to launch the simulator through command line by struggling for many hours but it doesn’t open my application inside the simulator and then i see the at bottom it encountered another problem.

An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2):
Failed to install the requested application
An application bundle was not found at the provided path.
Provide a valid path to the desired application bundle.

i went through many articles and tried to fix but no luck.

Finally, this the cli is always making problems to compile the application?

I made ionic app within the 3 days but fixing this problem is taking me ages. i don’t understand what’s wrong with that. this is making me to jump to another framework assuming its the only problem with ionic.

Not sure but for some reason it has started to work on my emulator without doing anything. Weird…
Thanks for checking
