steakhal added a comment.

I had some improvement opportunities in mind scattered, so I decided to do 
them, and here is how the diff looks for me now: F27853795: 
recommendation.patch <https://reviews.llvm.org/F27853795>

Basically, I reworked the two branches a bit to express the intent more strait 
forward.
I also enable all `osx.cocoa` checkers, as this file is all about objc stuff 
anyway - this also meant to diagnose two non-fatal leak errors, which are not 
tied to this patch otherwise.

I'm also testing that the "assumption" after the objc call thingie (message 
passing?) the pointer is assumed to be "nonnull". For this, I'm using the 
`eagerly-assume=false` to ensure we don't split null and non-null states 
eagerly when we encounter the `p == nil` inside `clang_analyzer_eval()` call 
argument.

I think all my changes are aligned with your intent, right?

One more thing I was thinking of was to make this ObjC null checking checker 
depend on the "nullability" checker package, but it turns out we can only 
depend on individual checkers as of now. I tried some ideas there, e.g. 
depending on the base checker of that package but it didn't work, so I dropped 
the idea. (`clang/include/clang/StaticAnalyzer/Checkers/Checkers.td`)

Do you plan to contribute more ObjC-related fixes in the future?
Please note that I have absolutely no experience with ObjC stuff.

And I also wanted to thank you for the high-quality patches you submitted so 
far!
