从应用商店更新我的应用后，我的应用无法打开

Question

我尝试在应用商店触发新版本，然后我将用户重定向到应用商店。然后在里面我更新应用程序。完成下载后，我点击应用程序商店内打开然后我的应用程序将打开一个闪屏，然后它将自动关闭。我没有得到任何崩溃日志。这是我的代码。

DispatchQueue.global().async {
        do {
            let update = try self.needsUpdate()

            print("update",update)
            DispatchQueue.main.async {
                if update{
                    self.popupUpdateDialogue();
                }

            }
        } catch {
            print(error)
        }
    }


func popupUpdateDialogue(){
    var versionInfo = ""
    do {
        versionInfo = try self.getAppStoreVersion()
    }catch {
        print(error)
    }


    let alertMessage = "Please update this app to version "+versionInfo;
    let alert = UIAlertController(title: "New Version Available", message: alertMessage, preferredStyle: UIAlertControllerStyle.alert)

    let okBtn = UIAlertAction(title: "Update", style: .default, handler: {(_ action: UIAlertAction) -> Void in
        if let url = URL(string: "itms-apps://itunes.apple.com/sg/app/myApp/idxxxx"),
            UIApplication.shared.canOpenURL(url){
            if #available(iOS 10.0, *) {
                UIApplication.shared.open(url, options: [:], completionHandler: nil)
            } else {
                UIApplication.shared.openURL(url)
            }
        }
    })
    let noBtn = UIAlertAction(title:"Skip this Version" , style: .destructive, handler: {(_ action: UIAlertAction) -> Void in
    })
    alert.addAction(okBtn)
    alert.addAction(noBtn)
    self.present(alert, animated: true, completion: nil)

}


func needsUpdate() -> Bool {
    let infoDictionary = Bundle.main.infoDictionary
    let appID = infoDictionary!["CFBundleIdentifier"] as! String
    let url = URL(string: "http://itunes.apple.com/sg/lookup?bundleId=\(appID)")
    let data = try? Data(contentsOf: url!)
    let lookup = (try? JSONSerialization.jsonObject(with: data! , options: [])) as? [String: Any]
    if let resultCount = lookup!["resultCount"] as? Int, resultCount == 1 {
        if let results = lookup!["results"] as? [[String:Any]] {
            if let appStoreVersion = results[0]["version"] as? String{
                let currentVersion = infoDictionary!["CFBundleShortVersionString"] as? String
                if !(appStoreVersion == currentVersion) {
                    print("Need to update [\(appStoreVersion) != \(currentVersion)]")
                    return true
                }
            }
        }
    }
    return false
}

我真的不知道为什么该应用会自动终止/关闭。我还检查了此链接App Crash when after updating，https://stackoverflow.com/questions/17795920/ios-app-goes-crash-on-startup-after-updating-from-the-app-store,https://stackoverflow.com/questions/15409323/ios-app-cannot-be-opened-after-update但仍无法解决此问题。
