Swift SIGABRT 错误？但是我解决了吗？

Question

我还有一个错误，这是常见的 swift 错误

Thread 1: signal SIGABRT

我知道如何修复这个错误。这是我最近的问题。

但是现在我正在做一个新的项目，我得到了这个错误！所以我试图修复它，我以为我明白了 - 但我没有..我检查了我所有的插座和所有东西，但没有任何痕迹表明这是从哪里来的......

这是我的代码：

导入 UIKit

class ViewController: UIViewController {
//Variables
var tempature:Int = 50
var battery:Int = 100
var monsterCount:Int = 0

//Outlets
@IBOutlet weak var BatteryLevel: UILabel!
@IBOutlet weak var TempDisplay: UILabel!

//The spy camera
@IBOutlet weak var monsterImageDisplay: UIImageView?

//The background image
@IBOutlet weak var backgroundImageShow: UIImageView!

//Functions
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    monsterImageDisplay?.isHidden = true
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

//The interval to keep things going
var helloWorldTimer = Timer.scheduledTimer(timeInterval: 3.0, target: self, selector: Selector(("spawnMonstor")), userInfo: nil, repeats: true)

func spawnMonstor() {
    monsterImageDisplay?.isHidden = false
    monsterCount += 1
    if monsterCount >= 3 {
        let randomNumberBackgroundImage = arc4random_uniform(10)
        if randomNumberBackgroundImage >= 5 {
            backgroundImageShow.image = UIImage(named: "main-room-jumpTop")
        } else if randomNumberBackgroundImage <= 5 {
            backgroundImageShow.image = UIImage(named: "main-room-jumpBottom")
        }
    } else if monsterCount >= 5 {
        let alert = UIAlertController(title: "GAME OVER", message: "Sorry! You died...", preferredStyle: UIAlertControllerStyle.alert)
        alert.addAction(UIAlertAction(title: "Okay..", style: UIAlertActionStyle.default, handler: nil))
        self.present(alert, animated: true, completion: nil)
    }
}


//The shock rooms button

@IBAction func ShockRooms(_ sender: Any) { monsterImageDisplay?.isHidden = true
}

}

检查您的 UIImage 名称是否与 xcassets 文件夹中的名称完全相同。
不要使用 helloWorldTimer，而是将此写在 class 的顶部，在您的插座下方：

var helloWorldTimer = Timer()

然后在您的 viewDidLoad 中添加：

helloWorldTimer = Timer.scheduledTimer(timeInterval: 3.0, target: self, selector: Selector(("spawnMonstor")), userInfo: nil, repeats: true)
