Thanks for pushing this forward! Current proposal seems to be only dealing with annotating ObjC for Swift, but API notes seem like a feature that would be useful for other languages as well. I briefly chatted with gribozavr and we concluded that if the need arises, the current design should be extensible to e.g. C++ (one of the bigger problems being how to name C++ function/overload sets). ================ Comment at: clang/docs/APINotes.rst:187-190 + - "N"onnull (``_Nonnull``) + - "O"ptional (``_Nullable``) + - "U"nspecified (``_Null_unspecified``) + - "S"calar (deprecated) ---------------- compnerd wrote: > rsmith wrote: > > Is it important that these are single letters?

Depending on the details it might be reasonable to drop NullabilityOfRet attribute completely, or more precisely document when it should be used.
