This is the first time I am opening a project up that was already made. I had trouble at first with the story board where it said no editor. But I manually added those files and they appeared to be working. However, when I build it I get an error in the AppDelegate.swift file on the line with : "class AppDelegate: UIResponder, UIApplicationDelegate { <"Thread 1: signal SIGABRT">
IM USING Version 8.2.1 (8C1002)
This pops up at the bottom:
