If you're an iOS Developer. You've probably heard of Reveal.

It's a powerful runtime view debugging tool for iOS developers.

If you have a jailbroken iOS device. You're possible to debug any other's apps without having its source code.

I'll show you how to inspect with iOS 12.

Preparing

brew cask install reveal

Jailbreak an iOS device. My tutorial.

Install Xcode

mas install 497799835

git clone https://github.com/HackingGate/Reveal2Loader.git
cd Reveal2Loader

Build .deb package

make clean
make
make package

Upload .deb package to jailbroken iOS device

scp releases/debs/naville.revealloader2_1.0.0-1_iphoneos-arm.deb [email protected]:~/

SSH login in jailbroken iOS device

ssh [email protected]

Install .deb. It will download RevealServer.zip form my download center. And set everything up.

dpkg -i naville.revealloader2_1.0.0-1_iphoneos-arm.deb

On your jailbroken device. Open Settings -> Reveal

Enable applications you want to inspect

Open Reveal.app. You'll see inspectable apps appear.

Reveal only works on Apple's own UI framework. Frameworks such as Flutter only shows one layer.
