Why is not same the .car file size?

Hello 🙂



first of all i am not a native speaker so,

I can not make the right sentence. so i will use a google translator.



i've a two target in one project. when i build each target, there is not same or neary size.



So, i checked each .ipa files , i found it dosen't have similar size.(There is a difference of 20MB)



using actool, i extracted files, Image is almost same But Some files dose not have the same size.



How should I solve these problems?



p.s.

build setting is same. asset catalog is almost same. there is not a exactly same image files but almost same.

And When i Extracted two .ipa files, it has almost same size.
