各位大佬，Swift 可否逆向？

%hook ViewController

- (void)viewDidLoad {
    %orig;
    NSLog(@"VIEW DID LOAD");
}

%end

%ctor {
    %init(ViewController = objc_getClass("HookExampleApp.ViewController"));
}

或

static void (*orig_ViewController_randomFunction)(void) = NULL;

void hook_ViewController_randomFunction() {
   orig_ViewController_randomFunction();
   NSLog(@"Hooked random function");
}

%ctor {
    %init(ViewController = objc_getClass("HookExampleApp.ViewController"));
    MSHookFunction(MSFindSymbol(NULL, "__T014HookExampleApp14ViewControllerC14randomFunctionyyF"),
                   (void*)hook_ViewController_randomFunction,
                   (void**)&orig_ViewController_randomFunction);
}

或
getImplementation
setImplementation
