Access viewController 'view' from inside a class?

Hi Spencer,

There are a few ways to do this. If you're following the MVC pattern the approach to take depends on the role of the object you're instantiating in the view controller. The iOS Design Patterns course covers MVC if you're not already familiar with it. There's also a great lecture on MVC in the Developing iOS 11 Apps with Swift course (it's the second video).

If possible, it would be good if the view controller itself could update its own view to prevent coupling the view controller to the object instantiated in it.

If the object is a view, delegation is a great option. Check out the Delegation in iOS course if you're not familiar with this design pattern.

If the object is part of the model the communication channel should be even more loosely coupled because the model should never directly interface with a view. Key Value Observing (KVO) and notifications are good options for notifying the view controller that it needs to update its view. The iOS Design Patterns course covers both of these options.
