IB outlets and actions causing the error Thread 1:Signal Sigabrt

I am currently creating a fitness app for the iPhone through Xcode. It has three different view controllers and a file attached to each one. I am currently working in the second view controller with the second file, and I have currently just added four IB outlets to the code and a IB action for a button. However, when I run the code, it freezes in the simulator and takes me back to a screen with the AppDelegate class, and it has a red area that says Signal Sigabrt. When I remove all of the outlets and actions, the program runs fine and everything works perfectly, but when I add even one outlet, the simulator freezes again and the Signal Sigabrt comes back again. I read online in many other posts that this is because of a connection problem between the elements and the outlets and actions, so I deleted the action and outlets through the Connections Inspector and I reconnected everything again. However, this did not solve anything, and I am still stuck with the same Signal Sigabrt problem. I looked through what the Debugger was giving me and it says that the Breakfast1 outlet is wrong, so I removed that outlet through the Connections inspector and ran the program again, but it just keeps on telling me that the next outlet is wrong and it gives me the Signal Sigabrt again. Has anybody else had this issue and can help me solve it?

My ViewController2 Code:

import UIKit
class ViewController2: UIViewController {
    @IBOutlet weak var Breakfast1: UITextField!
    @IBOutlet weak var Lunch1: UITextField!
    @IBOutlet weak var Dinner1: UITextField!
    @IBOutlet weak var Total1: UILabel!


    override func viewDidLoad() {
        super.viewDidLoad()
        /
    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        /
    }

    @IBAction func addingButton(_ sender: Any) {
    }

}

What the Debug area is giving me:

I had the same issue. But when I created a new cocoa file and added it to the ViewController it was resolved. It seems that the file was corrupted because it would bee keep on adding those gray circles on the side of the code after running it.

It looks like you have not set the correct class for the view controller in Interface Builder.

With the view controller selected, in the right side of the Interface Builder in the Identity Inspector set the class to ViewController2 .

Ok it looks like you might have renamed one of your outlets just using one of the Xcode editors, but this breaks the connection of your outlet to your actual button/label. To fix this you open your swift file that your having a problem with as source code and edit the name in there. This will fix your break between the IBOutlet. I hope this works lmk and I can help your further if it doesn't.
