EDIT :-

WARNING :- Don't make .ipa with changing extension from .aap to .zip and .zip to .ipa.

I have seen in many answer that , they have suggest compress .app file and then change the extension from .zip to .ipa . It is not working now . By this method you will get Error like ,

IPA is invalid, it does not include a payload directory.
