Access View Controller method from App Delegate in Swift - asking for parameter

Question

I am trying to call a method from my view controller in the app delegate file, and it is asking for a parameter of the type of whatever class I am trying to call. ie: what is happening is that I am trying to call a method from the messages_send_message.swift class / file, and for any method in that file (including the ones without parameters) it wants a parameter of messages_send_message .

what is happening: I am trying to call the update method from the app delegate file when it receives a push notification. So that if they are already in the chat, it just updates/refreshes the feed.

so here is the method: messages_send_message.update() and it is asking for: messages_send_message.update(messages_send_message)

But it throws an error by that parameter when I try to use it. I also tried putting the () after the messages_send_message parameter, but same issue, still get the errors.

Anyone know a fix?

By the way, the error is: Missing argument for parameter #q in call

Answer 1

If your update doesn't reference self, then make it a class method and that will fix your problem.

If the method does reference self, then you need an instance of the class to call the method.
