分段错误 11 仅适用于 xcode 10 swift 3

Question

我将 xcode 9.4 与 swift 3 一起使用，代码运行良好，并且已上线。现在，当我运行我在 xcode 10.1 中使用相同的代码时，我收到许多 segmentation fault 11 错误 files.Not 确定我该怎么做 that.And 我该如何转换我的swift 3 到 swift 4。因为很多文件我需要更改语法。

最好我需要在 xcode 10.1 中使用 swift 3 并且需要解决 segmentation fault 11.

我在这里遇到的主要错误：

While emitting SIL for 'application(_:didReceiveRemoteNotification:)' at /Users/Documents/Rough/jeder/JEDE_r/AppDelegate.swift:258:5

While silgen emitFunction SIL function "@$S3WCi11AppDelegateC11application_28didReceiveRemoteNotificationySo13UIApplicationC_SDys11AnyHashableVypGtF". for 'application(_:didReceiveRemoteNotification:)' at /Users/Documents/Rough/jeder/JEDE_r/AppDelegate.swift:258:5 error: Segmentation fault: 11

我的代码：

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) 
{
    if application.applicationState == .inactive || application.applicationState == .background {
        //opened from a push notification when the app was on background
    }
    else
    {
        if application.applicationState == .active
        {
            let myuserinfo = userInfo as NSDictionary
            print(myuserinfo)

            let tempDict:NSDictionary = (myuserinfo.value(forKey: "aps") as? NSDictionary)!
            let alert = UIAlertView(title: "alertView", message: (tempDict.value(forKey: "alert") as? String)!, delegate: nil, cancelButtonTitle:"Cancel", otherButtonTitles: "Done", "Delete")
            alert.show()
            let person:NSDictionary = (tempDict.value(forKey: "custom") as? NSDictionary!)!
        }
    }
}

这里有什么问题。我怎样才能解决所有 segmentation fault 11 错误，近 22 个文件显示该错误。

请提供任何帮助！！

Answer 1

更改此行：

let person:NSDictionary = (tempDict.value(forKey: "custom") as? NSDictionary!)!

到

let person:NSDictionary = (tempDict.value(forKey: "custom") as? NSDictionary)!

同样在同一个应用程序中委托另一种方法，你也这样做。用上面的那一行替换那一行。可能是这个帮助。如果您有任何其他问题，请告诉我或post。

请尝试以下代码

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any])
    {
        if application.applicationState == .inactive || application.applicationState == .background {
            //opened from a push notification when the app was on background
        }
        else
        {
            if application.applicationState == .active
            {
                let myuserinfo = userInfo as NSDictionary
                print(myuserinfo)

                let tempDict:NSDictionary = ((myuserinfo.value(forKey: "aps") as? NSDictionary))!
                let alert = UIAlertController(title: "alertView", message: (tempDict.value(forKey: "alert") as? String)!, preferredStyle: .alert)
                let ok = UIAlertAction(title: "OK", style: .default, handler: nil)
                alert.addAction(ok)
                //alert.show()
                self.window?.rootViewController?.present(alert, animated: true, completion: nil)
                let _:NSDictionary = (tempDict.value(forKey: "custom") as? NSDictionary)!
            }
        }
  }
