Xcode 8 iOS 10 non-stop logs

Question

The log of my Xcode 8 device with iOS 10 iPhone 6s + does not print the following lines continuously, and I can’t stop it or don’t know how to stop it. Anyway, can I stop them from printing?

Sep 20 14:34:41 iPhone kernel(AppleBiometricSensor)[0] <Debug>: Status={0x80, 0x20, 00, 0x10, 00, 00, 00, 0x11, 0x1, 0x1, 00, 0x4, 0xf0, 0x2, 0x9, 00} Sep 20 14:34:41 iPhone kernel(AppleBiometricSensor)[0] <Debug>: Sent message of 20 bytes Sep 20 14:34:41 iPhone kernel(AppleBiometricSensor)[0] <Debug>: exit, err=0x0 Sep 20 14:34:41 iPhone kernel(AppleBiometricSensor)[0] <Debug>: mask=0xFF, bad=false Sep 20 14:34:41 iPhone kernel(AppleBiometricSensor)[0] <Debug>: exit Sep 20 14:34:41 iPhone kernel(AppleBiometricSensor)[0] <Debug>: entry Sep 20 14:34:41 iPhone kernel(AppleBiometricSensor)[0] <Debug>: exit Sep 20 14:34:42 iPhone kernel(AppleBiometricSensor)[0] <Debug>: entry Sep 20 14:34:42 iPhone kernel(AppleBiometricSensor)[0] <Debug>: entry Sep 20 14:34:42 iPhone kernel(AppleBiometricSensor)[0] <Debug>: txBufferLength=7 rxBufferLength=23 Sep 20 14:34:42 iPhone kernel(AppleBiometricSensor)[0] <Debug>: Wrote: 7B | 0x80 0x10 0x00 0x07 0x00 0x00 0x00 Sep 20 14:34:42 iPhone kernel(AppleBiometricSensor)[0] <Debug>: Read: 23B | 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x80 0x20 0x00 0x10 0x00 0x00 0x00 0x11 

PS: I tried disabling the touch id, but no luck.

Also, I'm not talking about console magazines. I am talking about device logs.

Answer 1

Switch to macOS Sierra and use the redesigned console application. Now it lists the connected devices and allows for advanced filtering and searching for device logs, the best thing that Xcode has been able to achieve in the past, for example. by process name, as shown in the screenshot below:

Note: this new application, unfortunately, uses 30% of the processor while open, I hope that Apple can fix it, in the meantime, be sure to drop it when the mobile phone or withstand a serious battery drain.

Answer 2

This is just a workaround. You can try using the iOS console , which allows you to filter content.

Answer 3

This issue is independent of xcode 8 and xcode 7. The message “kernel (AppleBiometricSensor) [0]:” will disappear if you put your iOS device into sleep mode and come back again if you click on it.

iOS 10.0.2 Update → NO FIX

Answer 4

The device log enables NSlog. Please, you can try nslog instead of printing. A.
