I am new to swift and objective-c and seeking help.
I have a swift class file that needs to use 2 methods however I am not sure how

@objc(ReactNativeMidiModule)
class ReactNativeMidiModule: (ObservableObject, RCTEventEmitter){
  //code...
}

I need this class to use both ObservableObject, RCTEventEmitter. I am now sure if that can be done or how to do it as I get the following error

Inheritance from non-protocol, non-class type '(ObservableObject, RCTEventEmitter)'
Only classes that inherit from NSObject can be declared @objc
