How to get information about free memory and running processes in an App Store approved app? (Yes, there is one!)

Works like a charm:

#import <sys/sysctl.h>

iphone ios ipad memory process

sysctl is no longer accessible to sandboxed iOS 9 apps.

From WWDC 2015 session 703 Privacy and Your App:

In iOS 9, the sandbox now prevents a process from accessing the kern.proc, kern.procargs, and kern.procargs2 values for other processes

and

iOS apps are not permitted to see what other apps are running

So even if you find a way, you are likely to get rejected from the App Store.
