Why is the IPA file size so massive for small games when UE4 exports projects?

The cooked .pak file is 57 MB and I created the project without starter content and my assets folder is only 3 MB large. What am I missing?

Edit: I opened up the .ipa and discovered that there’s a feature called Slate in the engine that was 15 MB and I’d like to turn it off. Is it possible?
