I am wondering what exactly is the binary, contained in the .ipa file ( iOS app distribution ) ? And what is its extension ?
On this link https://apple.stackexchange.com/questions/26550/what-does-ipa-stand-for, I have read
Each .ipa file is compressed with a binary for the ARM architecture that can only be installed on iOS devices. If you change the extension to .zip you will be able to unzip it and view the contents.
So is this binary the app_name.app file ?
