The method call to
-[NSFileManager temporaryDirectory]
was added in #391. However, it is only available on iOS 10.0+ and MacOS 10.12+ (source), thus causing crashes on iOS 9.Fix by switching to
NSTemporaryDirectory()
. Although it's not the preferred way (see the discussion here), it's good enough for now.
