Does Non used assets in project window affect total size of output file?

Hello everyone!
I am working on a mobile game and the size of of the output is about 40 MB which is more than what I want…
I have been importing packages but used some part of it.
I need to know if the non used assets also count on the size

Not used assets are not Shipped with the App automatically at the build porcess .
The only exception is the “Resources” and Streaming Assets Folder witch is defetifly included into the app.

For example:
My Assets folder :1,13 GB
My iOS app size 48 MB

Yes unused packages increase size but i don’t know with how much. But i strongly recommend you to remove the unused packages.
