Compiler warnings when switching Deployment Target

[RaoulNL]

L.S.,

When setting the deployment target to 10 I see 9 compiler issues, saying OSSpinLock is deprecated since iOS 10.0. (Use os_unfair_lock() from <os/lock.h> instead. There are three other similar calls which are also deprecated.
Can these warnings be fixed, since most new apps target at least iOS 10?

Feeel free to fix it and prepare PR

I can see that my changes have been approved and merged into the master branche.
However when I add the Pod to my project I do not see my changes.
Using the tool podchecker it says, that version 2.4.3 of this repo is used.
What am I missing?
