These are still disabled by default, but will work in ObjC code if you enable the `-import-insertions` flag. Completion requires ASTSignals to be available; before ASTSignals are available, we will always use #include. Once they are available, the behavior varies as follows: - For source files, use #import if the ObjC language flag is enabled - For header files: - If the ObjC language flag is disabled, use #include - If the header file contains any #imports, use #import - If the header file references any ObjC decls, use #import - Otherwise, use #include IncludeFixer support is similar, but it does not rely upon ASTSignals, instead it does the above checks excluding the scan for ObjC symbols.
