JIT on non-jailbroken iOS

[[Unknown]]

No, iOS doesn't allow apps to create executable memory. The only exception is for web browser JavaScript engines, which is a special "entitlement".

Most jailbreaks replace the iOS function that creates memory with one that allows all apps to create executable memory.

The issue isn't really about code signing.

It might be possible to make it work if:
1. You are willing to always run it on your phone by plugging it into a laptop or computer (you won't be able to launch it without one.)
2. You're willing to keep it plugged in to that laptop or computer for the entire duration of your usage (it closes automatically if disconnected.)

But at that point, why not just play it on the laptop or computer instead?
