What is the Console Output for?

Wanted to ask what the purpose of the Console output is? my guess is that it is what the phone is going to show on screen what you printed in the Console Output.

I think Console Output is good for debugging . Lets say that you wrote an login application where there is a UIButton that should give a user accesses after he entered his username and password but for some reason it is not happening so you could write a println() code like println("button was pressed ") . Later on when you run the application then pressed the button again , if the message did not show up on the screen you will know that this code block for the UIButton is not be executed.. Hope that help :)
