I was able to position the UI elements on the page using constraints. I made sure they display as I want them for all devices. I achieved this goal by setting up constraints for each of the layouts. I linked each element to one another as opposed to the position relative to the screen. It is important to do it this way since the user can switch from landscape to potrait.

While working with Interface Builder you are able to see filled in circles in the XCode IDE, next to the line number, which indicates that an action is mapped to a UI element.

IBOutlet is the code that interacts with the UI IBInput logic that executes after triggering an event

My favorite quote from this exercise

In programming, you have to keep the attitude of a child. You have to be willing to experiment and to try new things.
