Hello all. I am on the second project for the iOS techdegree and I am confused. XCode is telling me I have errors and they don't even make sense. My project is in the link below (GitHub). Would someone be so kind as to review my project so far and tell me what I may have wrong? Thank you very much.

9,541 Pointsin your viewController.swift file, the check answer IBAction, you are missing a ')' at the end of the if statement
if (sender === button1 && correctAnswer == true) || (sender === button2 && correctAnswer == true) || (sender === button1 && correctAnswer == true) || (sender === button2 && correctAnswer == true)
For the error Variable 'correctAnswer' captured by a closure before being initialized
you have to initialize the correct answer variable, maybe to something like var correctAnswer = false
