Xcode 8 iOS 10 non stop device logs

Question

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?

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 touch id but no luck.

Also, I am not talking about console logs. I am talking about the device logs.

Answer 1

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:

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.

Answer 2

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