cocos2d-x-3.0alpha1 touch events?

I’m just getting started with cocos2d-x and am using the 3.0 alpha 1 version. I have the following code below trying to setup to handle an onTouchBegan event, but I’m getting an error in Xcode saying "Incomplete type ‘cocos2d::EventListenerTouch’ named in nested name specifier.
@
auto *touchListener = EventListenerTouch::create;
*touchListener~~>setSwallowTouch;
_touchListener~~>onTouchBegan = [](Touch* touch, Event* event){ this->touchMe(touch, event); return true;};
@

auto *touchListener = EventListenerTouchOneByOne::create;
*touchListener~~>setSwallowTouch;
*touchListener~~>onTouchBegan = []{ this~~>touchMe; return true;};
*eventDispatcher~~>addEventListenerWithSceneGraphPriority(_touchListener, this);

you can find examples under the samples/Cpp/TestCpp/Classes
