🔎Analyse assets

Generate an IPA with xcode (archiving -> adhoc -> in adhoc options "App Thinning" set to "None", see explantions).

NOTE: If you want to reverse and study 3rd party application, you need a jailbroken device to extract IPA.

NOTE: you can for example change assets and rename back from zip to ipa.

Prepare

rename APP_TO_STUDY.ipa to APP_TO_STUDY.zip
unzip (you should see a payload new directory as a result)
you have now APP_TO_STUDY.app in the payload directory.

Study assets

in Finder, right click on APP_TO_STUDY.app then select view all content
you have now access to assets, plists, storyboards etc...

Disassemble code (Hopper or any other disassembler)

open APP_TO_STUDY.app in Hopper (should be automatic, but be sure to open with loader Mach-O AArch64)
in search input, type for example: appDelegate to see related ARM code related to appDelegate in the application.
