...located. Before SectionMemoryManager::finalizeMemory() method is called I register the ObjC runtime classes. 2) I iterate over __objc_selrefs sections and fixup selectors. This does fix the original crash of this thread. 3) I iterate over __objc_classlist sections and register the new classes using objc_allocateClassPair function, register the properties and ivars to these new classes, run objc_registerClassPair to complete the registration. (I still have to implement the protocol registration) 4) I iterate over __objc_classrefs and __objc_superrefs and fix up the class pointers with the new classes created at step...

The Objective-C runtime provides public APIs for doing all of this. They’re
