-Wobjc-messaging-id is a new, non-default warning that warns about message sends to unqualified id in Objective-C. This warning is useful for projects that would like to avoid any potential future compiler errors/warnings, as the system frameworks might add a method with the same selector which could make the message send to id ambiguous. rdar://33303354 llvm-svn: 311779
