The 6 inspectors in XCode

shows you all the file details related to this
one view　　

shows you quick help documentation related to
view controllers

lets you see and change the class that represents the view controller
for this particular scene

This tab within the inspector is particularly important because you’ll be using it
whenever you want to point a UI control to a custom class you’ve created within your
project

allows you to change any attribute on the
currently selected object.

eg: You commonly use this section to change titles of buttons and other
visible properties on an object

you can modify all
aspects of a view’s framing

Below that is a section called Constraints, which you used to set the auto-layout
constraints

you can see the outlet connections we made for the tableView property on
the view controller as well as the table view’s delegate and dataSource properties
