Xcode doesn't write anything to output console

Question

I am working on an iPhone/iPad app. All of a sudden output console stopped displaying ANY messages AT ALL. I tried to open older project - works just fine. So I thought that

Answer 1

This question appears all over the place and is a valid one pointing to a random bug in most versions of xcode. Obviously the majority of people arriving at these answers are just unable to use xcode and therefore credit the 'show the console' type answers. I have worked on a single major project for 6 years now and this appears every month or so. I reboot devices, restart xcode, stand in the corner singing yankee doodle dandy. Nothing has occurred to me as an obvious and repeatable fix. Eventually I will start work one morning and it will be working again. Nothing I have done will be an obvious fix, no updates will have been installed. Just a heads up to those thinking they are going mad.

Answer 2

Xcode 10.1 targeting iOS 11, Xcode stopped displaying console output from one build to another minutes later.

I have OS_ACTIVITY_MODE as an environment variable in my scheme and I get no output in the console in Xcode.

If I disable or remove OS_ACTIVITY_MODE from my scheme my log appears in the console - alas with a lot of system logging as well.

Try disabling OS_ACTIVITY_MODE from Edit scheme > Run, in the section Environment Variables if you have it set there.

Answer 3

Not exactly sure what was happening, but everything works just fine now (after I started Xcode again today). I did have everything turned on (showing output console with "all" checked).

I appreciate everybody's help.
