I followed this CocoaPods Tutorial to install pod for Starscream, a websocket library we use for this game.
I wanted to build a joystick to control the movement of my dot. To get myself more familiar with how to use CocoaPods, I searched for pods for joystick, and I found this JoystickView pod view easy to understand and follow, so I installed another pod for this project.
My code was having a few runtime errors. After looking at the documentation and example project on Github, I found out it was because my views were not wired correctly. When adding a custom class like this JoystickView, I have to go into identity view controller to add Class name and module name.
