| The LLVM CLANG language extensions page* documents an Objective-C extension called “instancetype”. But when I tried to use this in Xcode 4.2 using the “Apple LLVM 3.0” compiler, it doesn’t recognize the extension. __has_feature(objc_instancetype) evaluates to false, and using “instancetype” as the return type of a method causes a syntax error. What’s going on?
According to “clang --version” I’ve got "Apple clang version 3.0 (tags/Apple/clang-211.10.1) (based on LLVM 3.0svn)”. |
