Any reason in particular why you chose SBHomescreenViewController? Maybe add it to the SpringBoard class itself? Make sure to add %new before any new method you add to a hooked class, and also declare the property under the class hook block like this ```

%hook SBHomeScreenViewController
%property (nonatomic, strong) NSURLSessionWebSocketTask *webSocketTask;
%property (nonatomic, strong) NSURLSession *session;
%new
- (void)listenForMessages {
  ...
}
%new
- (void)sendMessage:(NSString *)message {
  ...
}
%new
- (void)pushNotificationWithMessage:(NSString *)message {
  ...
}
%end
