"Reading from public effective user settings" in iOS 10
提问by TenaciousJay
I'm getting the following messages when launching my app:
启动我的应用程序时，我收到以下消息：
2016-10-12 14:47:23.705002 Discovery[377:147958] [MC] System group container for systemgroup.com.apple.configurationprofiles path is /private/var/containers/Shared/SystemGroup/systemgroup.com.apple.configurationprofiles
2016-10-12 14:47:23.712212 Discovery[377:147958] [MC] Reading from public effective user settings.
Is "system group container" related to App Groups? I do share data between apps using an App Group and was wondering if this caused this message to be displayed?
“系统组容器”是否与应用组有关？我确实使用应用程序组在应用程序之间共享数据，并且想知道这是否会导致显示此消息？
I set the data in one app like this:
我在一个应用程序中设置数据，如下所示：
var userDefaults = NSUserDefaults(suiteName: "group.com.company.myApp")
userDefaults!.setObject("user12345", forKey: "userId")
userDefaults!.synchronize()
And I retrieve it in another app using something like this:
我使用这样的东西在另一个应用程序中检索它：
var userDefaults = NSUserDefaults(suiteName: "group.com.company.myApp")
if let testUserId = userDefaults?.objectForKey("userId") as? String {
print("User Id: \(testUserId)")
}
Did something change in iOS 10 that would cause any problems or cause these messages to show up?
iOS 10 中是否有什么变化会导致任何问题或导致这些消息出现？

This is a bug (now we're finding out it might be a permanent message) and it seems that this message appears primarily when clicking on a Text Field or Text View or other similar NSObject.
这是一个错误（现在我们发现它可能是一条永久性消息），似乎该消息主要在单击文本字段或文本视图或其他类似 NSObject 时出现。
This is only a log message and not a compile error message as signified by the date and time preceding the message. Therefore if your code is not working it is not a result of this console message.
这只是一条日志消息，而不是消息前面的日期和时间所表示的编译错误消息。因此，如果您的代码不起作用，则不是此控制台消息的结果。
If you run on a device the message will be [MC] Reading from public effective user settings. If you run on the sim the message will be [MC] Reading from private effective user settings.
如果您在设备上运行，则消息将为[MC] Reading from public effective user settings。如果您在 SIM 卡上运行，消息将是[MC] Reading from private effective user settings.

Xcode seems to full of these confusing and misleading warnings. this warning appears when ever I enter text in a UITextField, at first I thought there is something wrong with my codes.
Xcode 似乎充满了这些令人困惑和误导性的警告。当我在 UITextField 中输入文本时会出现此警告，起初我认为我的代码有问题。

I was struggling with this issue in an iPhone5 emulator (on the device everything was ok) that stucked my Ionic app after touch a TextInput, and then I changed the emulator to another one, like iPhone6, or iPhone8, and everything worked again.
我在 iPhone5 模拟器中遇到了这个问题（在设备上一切正常），它在触摸 TextInput 后卡住了我的 Ionic 应用程序，然后我将模拟器更改为另一个模拟器，如 iPhone6 或 iPhone8，一切又恢复正常。
