Thread 1: signal SIGABRT

I am in the process of making a vending machine app and I keep getting this error message when I start the app up any ideas on what is wrong and how to fix it. I am very new to coding and don't know a ton

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var pressAddDoubleTap: UIButton!
    @IBOutlet weak var totalPrice: UILabel!
    var someValue: Double = 0.0 {
        didSet {
            totalPrice.text = "$\(someValue)"
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()

    }

    @IBAction func pressAddDoubleTap(_ sender: UIButton) {
    }

    @IBAction func buttonPressed(sender: UIButton) {
        someValue += 2.00
    }

    @IBAction func pressAddQuickRevive(_ sender: UIButton) {
    }
    @IBAction func pressAddSpeed(_ sender: UIButton) {
    }
    @IBAction func pressAddJug(_ sender: UIButton) {
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()

    }
}

often this happens when an outlet connection is missing or mislabeled some how. I would check to see if you have any outlets you made, and then deleted, and make sure there aren't any broken connections there

I changed this comment to an answer as it's precisely the advice I would have given. :+1:

Also happen when we commit a typo on the identifier of a cell or any other object. That's why is always a good practice to assign the identifiers to a constant. But in this case, might be missing outlet connections as Taylor Smith said. Look likes this error always happen when Xcode is looking for something that doesn't exist, don't match or has only a reference.
