Thread 1: "[<UIViewController 0x7ff3bdc08a80> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key leadingHome." I have tried: Deleting home and re-adding it reconnecting all the points on the home controller Deleting the class and re-adding it Making a new class and changing Home over to it Setting the constraints and menu button itself to the class You can download my project at: https://www.icloud.com/iclouddrive/0vC-WfbeKKjLa6V05ofqhyayw#Riddle_Wednesday Thanks so much in advance!
