NSLog not printing to console

Answer 1

This is a bug of Xcode8 + iOS10, we can solve it in this way:

When on simulator, add the Name OS_ACTIVITY_MODE and the Value Variables disable and check it (Product -> Scheme -> Edit Scheme -> Run -> Arguments -> Environment).

When on device, only add OS_ACTIVITY_MODE and check it（don't add the Value). You'll see the NSLog in the Xcode8 Console.
