Xcode 8 iOS 10 non stop device logs
提问by nitinsh99
My Xcode 8 device log from an iOS 10 iPhone 6s+ is printing the following lines non continuously and I can't stop it or don't know a way to stop it. Any way I can stop these from printing?
我来自 iOS 10 iPhone 6s+ 的 Xcode 8 设备日志非连续打印以下行，我无法停止它或不知道如何停止它。有什么办法可以阻止这些打印？

Also, I am not talking about console logs. I am talking about the device logs.
另外，我不是在谈论控制台日志。我说的是设备日志。

Upgrade to macOS Sierra and use the re-designed Console app. It now lists connected devices and allows advanced filtering and searching of the device logs, better than anything Xcode has been able to achieve in the past, e.g. by process name as shown in the screenshot below:
升级到 macOS Sierra 并使用重新设计的控制台应用程序。它现在列出连接的设备并允许对设备日志进行高级过滤和搜索，这比 Xcode 过去能够实现的任何东西都要好，例如通过进程名称，如下面的屏幕截图所示：
Note: this new app unfortunately uses 30% CPU while open, hopefully Apple can fix that, in the meantime be sure to quit it when mobile or endure serious battery drain.
注意：这个新应用很遗憾在打开时使用了 30% 的 CPU，希望 Apple 可以解决这个问题，同时确保在移动或忍受严重电池消耗时退出它。

This is just a workaround. You can try using iOS Consolewhich allows you to filter the content.
这只是一种解决方法。您可以尝试使用允许您过滤内容的iOS 控制台。

This issue depends NOT on xcode 8 it's also on xcode 7. The "kernel(AppleBiometricSensor)[0] :" messages will gone if you put the iOS device to sleep and back again if you press home.
这个问题不依赖于 xcode 8，它也在 xcode 7 上。如果你让 iOS 设备进入睡眠状态，“内核（AppleBiometricSensor）[0] :”消息就会消失，如果你按下 home 键又会返回。
iOS 10.0.2 Update -> NO FIX
iOS 10.0.2 更新 -> 没有修复

Device log only allow NSlog. Please could you try nslog instead print.
设备日志只允许 NSlog。请您尝试使用 nslog 代替打印。
