When I run my app the output says:
terminating with uncaught exception of type NSException
when I try to do an performseguewithidentifier or a UIAlert. I am parsing my json data but when I try to either do a UIAlert or a segue when that data equals something I get this error. What am I doing wrong?
import UIKit

@IBOutlet weak var nameInput: UITextField!
@IBOutlet weak var emailInput: UITextField!

override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
print(self.errorGot)
}

super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
