The text field placeholder and the "is really" label is hard to see at night. So i change their color depending one what time of day it is.
Also make sure you connect the new IBOutlet isReallyLabel. To do so open Main.storybaord and control-drag from "Convert" view controller to the "is really" text field and select the isReallyLabel under Outlets.
WARNING: I have not tested to see if the application is open while the time of day swaps.
