a view is just what the screen looks like. views just get displayed and thats it.

a view controller is what manages and controls views. it has one main view and that main view has many subviews such as buttons and labels. the view controller controls the view and subviews and can tell them what to display, when to display it etc. it manipulates the view and subviews.

iOS uses whats known as the Model-View-Controller design patter. you can read more about that here.

The view controller acts as an interface between the view (visual display) and the model (the data, logic, and rules thats used in your app such as names to be displayed in a table etc).
