NSLog statements not showing for iOS 10 in apple Configurator

Question

I have an app built using XCode 7.3 and it works fine with iOS 10.
But, the NSLog() statements that I had used for debugging earlier aren't showing up.
I could see them earlier inside apple configurator and now all I can see are so many kernel process messages.
The same is still working when I test an iOS 9.x device.
Kindly, update if this is resolved or is there any workaround.

If you have use XCode 8 then solution is below...

Goto -> Product -> Scheme -> Edit Scheme -> Run -> Arguments -> Environment Variables

In the Environment Variables: Perhaps you once added the Name "OS_ACTIVITY_MODE" and the Value "disable" and check it. But this way can lead to the Console cannot NSLog when the real iPhone debugging.

I solve it in this way: Only add "OS_ACTIVITY_MODE" and check it（Don't add the Value）

You can also see in below image

For XCode 7 You don't have any solution.

Alternative for this problem: I can't see NSLog output in real iOS 10 device neither. If you're using real devices, you can open Devices window from Xcode (Shift + Command + 2) and see device logs there, but it's hard to look at your app's logs because the console shows logs from system and all apps.

NOTE: If you check the Xcode 8 beta release notes, you'll find that it says: When debugging an app running on Simulator, logs may not be visible in the console. Workaround: Use command + / in Simulator.app to open the system log in the Console app to view NSLogs. (26457535)

I cannot test on a simulator and I have to test on a real device . So , is this way appropriate to see NSLogs ? – Amylose

I can't see NSLog output in real iOS 10 device neither. If you're using real devices – Bryna

You have to upgrade your XCode version – Bryna

So the NSLogs of a real device isn't possible to be seen now ? What am doing now is am writing all NSLogs to a file and then see that file to debug but this is taking a lot of time and I don't think this is the right way either . – Amylose

If you will upgrade your XCode version then it's Work like charm and First solution work for you – Bryna
