Does Apple modify iOS application executables on apps submitted to the App Store?

Question

Is an app\'s executable file byte-for-byte identical when the app is purchased through the App Store and installed on a user\'s iPhone, compared to the original executable f

Answer 1

The application is also stripped of your signature and signed by Apple. This can be verified by running "codesign -vvvvd" on the app binary you submit and comparing it to the output of "codesign -vvvvd" of the app binary you download from the store.

Because of this the hashes will not match.
