There’s a particular API that’s broken in iOS 8 (AVSpeechUtterance.rate), but 
not broken in iOS 7, and fixed in iOS 9. Using Xcode 7, therefore, I get the 
iOS 9 simulator, which means different speech behavior running in the simulator 
from running on an actual device (still running 8.3).

So I’m looking for a version check that will allow me to set the property based 
on the running iOS version, something like this:

> if (floor(NSFoundationVersionNumber) >= NSFoundationVersionNumber_iOS_8_0 && 
> floor (NSFoundationVersionNumber) < NSFoundationVersionNumber_iOS_9_0)
>       AVSpeechUtterance.rate = <the wrong value that used to work>
> else
>       AVSpeechUtterance.rate = <the right value>

but there’s no definition of NSFoundationVersionNumber_iOS_9_0 in the iOS 9 
SDK. In fact, there’s nothing higher than NSFoundationVersionNumber_iOS_8_1 in 
the iOS 9 SDK. That means there’s no definition that lets me test against 8.2, 
8.3 or 8.4.

I’m confused about what to do here. The iOS 8.3 SDK itself has no 
NSFoundationVersionNumber_iOS_8_x definitions at all, so going back to Xcode 6 
wouldn't solve the problem, except that the simulator would be 8.x, so the 
problem wouldn’t show up again until iOS 9 is released.

I must be missing something really obvious here.

(The app’s deployment target is currently set to 8.1, but I don’t think that 
makes any difference, except that I don’t care about iOS 7, which is 
unfortunately the one version I *could* check for.)
