<pre>CLANG_ANALYZER_NONNULL with Xcode 7.3 Beta 3 is giving incomplete warnings.
Steps to Reproduce:
NSString * _Nonnull foo = nil;
Actual result: no warning
Expected result: warning for converting from Nullable to Nonnull.
Workaround: one can define this macro...
#define __DARWIN_NULL ((void * _Nullable)0)</pre>
