When running the app on simulator, it crashes and say thread 1: breakpoint 3.1. What should I do?

I am new to programming and am trying to do an app right now. The problem started when I tried to make a Google Sign in button, and when I thought I had acheived that, I tried the simulator and none of my buttons worked when clicking on them, not even the text squares. Then the simulator started to crash with the code Thread 1: SIGABRT. I read on some place that you could do an exeption break point to see where the problem is, and when I did that I came to some lines, where on one it said Thread 1: Breakpoint 3.1.

import UIKit
import Google

class ViewController: UIViewController, GIDSignInUIDelegate {

    override func viewDidLoad() {
    super.viewDidLoad()

    GIDSignIn.sharedInstance().uiDelegate = self


    // Do any additional setup after loading the view, typically from a nib.

}


override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()

    // Dispose of any resources that can be recreated.
}
@IBOutlet weak var signinbutton3: GIDSignInButton!

@IBOutlet weak var signinbutton: GIDSignInButton!

func signInWillDispatch(signIn: GIDSignIn!, error: NSError!) {

}

// Present a view that prompts the user to sign in with Google
func signIn(signIn: GIDSignIn!,
            presentViewController viewController: UIViewController!) {
    self.present(viewController, animated: true, completion: nil)

    print("Sign in presented")
}

// Dismiss the "Sign in with Google" view
func signIn(signIn: GIDSignIn!,
            dismissViewController viewController: UIViewController!) {
    self.dismiss(animated: true, completion: nil)
    print("Sign in dismissed")
}



override func viewDidAppear(_ animated: Bool) {
    self.performSegue(withIdentifier: "loginView", sender: self); //this line is where the Thread 1: Breakpoint 3.1 was.


}

}

My problem shortly:

- The buttons on the simulator does not work

- The simulatior crashes and show on xcode the code sequence I showed before with the saying Thread 1: SIGABRT and Thread 1: Breakpoint 3.1 in the last line.

What do you think the problem is and how should I solve it? Edit I recieve this when trying to start the simulator:

I had the same issue with Xcode 9 and the simulator. I used a real device with iOS 11 and it was working fine (with some bugs though)
