当我在GamesViewController和GameItemViewController之间发生冲突时发生崩溃。
我的IBAction逻辑中没有任何异步任务，我开始实际的segue。我只检查3种不同的布尔值并分别启动不同的ViewControllers。
@IBAction func gameTapped(_ sender: Any) {
if x {
performSegue(withIdentifier: "x", sender: nil)
} else if y {
performSegue(withIdentifier: "y", sender: nil)
} else {
performSegue(withIdentifier: "showGameItem", sender: nil)
}
}
崩溃指向的这一行（GameItemViewController.swift：5）是视图控制器声明，如下所示：
import UIKit
import RxSwift
import RxCocoa
class GameItemViewController: UIViewController {
}
我还没有覆盖
init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?
OR
required init?(coder aDecoder: NSCoder)
我无法重新创建此功能，但是我可以看到多个设备遇到问题的崩溃问题日志。
