================
Comment at: lib/Sema/SemaDeclObjC.cpp:3859
+        // objc_subclassing_restricted attribute when it has that attribute as
+        // well (because of interfaces imported from Swift). Therefore we have
+        // to check if we can subclass in the implementation as well.

You typically wouldn't have `@interface`s in Objective-C code without corresponding `@implementation`s, so the attribute will act as expected for most cases. As well as that, you typically wouldn't care how Swift interfaces are declared in Objective-C. 
Works for me, thank you for the explanation!
