We have built a very small example app that contains a FirstController and a SecondController wrapped in a navigation controller.
You need to write the code to make this work.
The way this is intended to work is:
- The FirstController has a label that says "nothing yet".
- Clicking on "Second" segues to the SecondController, which has a textField. The FirstController must TELL the SecondController to specify "Change Me!" as the initial value of it's TextField.
- When the user hits the "Back" nav button, the SecondController informs the FirstController of the TextField's new value, which the FirstController sets as it's label's new value.
It's unorthodox, but we want you to write all the code for two controllers together in the supplied box (the "ViewController.swift" file).
You may work on this question in Xcode.
**Enter the full text of your `ViewController.swift` file (containing the full definitions of both controller types, plus anything else you need to define) it the answer field on GradeScope.**
