I'm trying to use the 2nd siri remote as the controller for my app, however I have encountered several problems. For the 1st siri remote, I can get the raw data of the trackpad, however the 2nd siri remote does not output the coordinate of the touch points. I want to know how can I get access to the raw data of the trackpad? I want to know how to get the button events of the remote. I have tried the method introduced in this tutorial https://developer.apple.com/news/?id=33cpm46r, but cannot get the button event.

I found that my 2nd generation siri remote does not work properly with the apple tv simulator. The central button and the back button works, but the 4 directional buttons and the sliding gestures do not work. However my 1st generation siri remote work normally. Does anyone know what the problem is? Thanks in advance.
