It was a very simple request - show an example?

Everyone commenting here is being hand wavy

I stated an example. It was not enough.

I used to write machine code, but I don’t, anymore. I am quite aware of how powerful it is, so I have to assume that the very smart people at Apple -who deal with current-day machine code- have a handle on dealing with it.

I guarantee that hackers do.

You didn’t state one example where it bypassed the sandbox. All apps on iOS are compiled to assembly. If writing in assembly magically bypasses a well designed OS’s security model, we are in trouble

Some things are worth arguing about.

This isn't one of them.

Have a great Thanksgiving!
