Almost every major third party app is using some private API or the other. There is even an internal list that Apple keeps of apps that are allowed to do. It’s quite trivial to bypass the App Store checks (which are quite bad and sometimes even flag legitimate use of system APIs).
The App Store process automatically checks for them and blocks submission.
Curious how apps are bypassing this and not sure why they would be trying to prevent debugging when it's not possible to do this.
