Xcode 8 iOS 10 non stop device logs

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}

PS: I tried disabling touch id but no luck.

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

Device log only allow NSlog. Please could you try nslog instead print.

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:iPhone log filtered by process

enter image description here

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.

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

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.

iOS 10.0.2 Update -> NO FIX
