Yes I have noticed and removed the connection.

I have tested the code like you said and I am getting the following result in the console: fightButton called BattleViewController instantiated navigationController nil Why am I getting navigation controller as nil? I have clearly added it in my storyboard. I am also getting this warning for the print statement for the navigation controller: Expression implicitly coerced from 'UINavigationController?' to 'Any'

Yes, i actually wanted to fix the issue,Thanks for the help!
