ReverseEngineering[0]: UnReel your Instagram
FLEX is a tool for debugging UI, memory, network, and other issues. It is much easier than debugging via terminal, so I am integrating this first. To do this (and to add our future script to modify content), we need to create a new framework, preferably in Objective C. We can create a Framework from Xcode > Create New Project > iOS > Framework. We should add the code there to launch the FLEX tool after a 2-second delay.

PSA: when people post screenshot of Buying / selling GME use fotoforensics.com to check if it’s been edited (using /u/XtraLyf 's post as an example)
There's also other ways to fake screenshots. For example on a jailbroken iPhone using flex you can literally change the content in a UILabel and then take the screenshot. No image editing necessary.

This approach is similar to the FLEX library, but it's only for HTTP traffic, not Websocket, and you have to directly inspect your iOS apps.
