Persistent queues are really useful. I have envied Android developers for having the Tape queue http://square.github.io/tape/ and the Android Priority Jobqueue https://github.com/yigit/android-priority-jobqueue

Below I have compiled a list of the persistent queue implementations for iOS that I know of. Most of them are not in active development. Ping me if you want a library added to the list.

• https://github.com/thisandagain/queue (Oleg Shanyuk has picked up development of this on https://github.com/gelosi/queue and Wolfpack-Digital on https://github.com/Wolfpack-Digital/queue)

CGFloat BNRTimeBlock (void (^block)(void));

#include <stdatomic.h>
#include <stdint.h>
#include <stdbool.h>

/*!
 An atomic ARC reference. Here's how it works:

 The lowest bit of the pointer (mask 0x1) is used as a tag for the pointer being stored.
 if the tag bit is set, that means that one thread currently owns this pointer, and will release it if the value has
 been concurrently updated.
