Summary:
The thread safety notes for NSNumberFormatter refer to NSDateFormatter instead:

“THREAD SAFETY

On iOS 7 and later NSDateFormatter is thread safe.

On OS X v10.9 and later NSDateFormatter is thread safe so long as you are using the modern behavior in a 64-bit app.

On earlier versions of the operating system, or when using the legacy formatter behavior or running in 32-bit on OS X, NSDateFormatter is not thread safe and you therefore must not mutate a date formatter simultaneously from multiple threads.”


Steps to Reproduce:
Go and look at the NSNumberFormatter docs, specifically the thread safety section.


Expected Results:
I expected to read about NSNumberFormatter’s thread safety.


Actual Results:
I actually read about NSDateFormatter’s thread safety. It’s not 100% clear whether I can assume that s/Date/Number/ will be accurate, either, so as it stands I’ve no idea what the thread safety of NSNumberFormatter is.
