How do I enable the XCode compiler to generate NX bit protected code?
A client has requested that I re-compile their app with this protection enabled. However, after reading the Security Document:
https://www.apple.com/business/site/docs/iOS_Security_Guide.pdf (section: "Runtime process security" starting on page 26)
I was under the impression that the NX bit security is enabled by default.
Is it possible to optionallly compile with NX bit security enabled? if so, how?
thanks,

iOS never allows an app to execute from writeable memory. You do not need to specifically enable the ‘NX bit’ because it’s always enabled for all third-party code.
