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

In my case it was due to hitting resource limits. iTerm was unable to fork new processes.

Quitting some apps or increasing resource limits may help.

Answer 2

Please make sure, You are selecting All Output

Answer 3

XCode 9, problem still exists. I did discover that when this starts to happen I don't show the debug area (middle button in pic). Then when I re-run the app, the debug area came back up with the console showing correctly.

Answer 4

Using filter?

A similar thing happened to me. In my case, I had by misstake entered a filter in the status bar of the debug area. Only rows that match the filter are displayed, and since my filter was rubbish nothing was displayed.

Answer 5

I had OS_ACTIVITY_MODE checked to disabled. once i removed this the console was showing debug info again.

Answer 6

This happened to me as well and it turned to be the following:

• installed release build of my app OTA
• installed over top of release build in XCode/debugger

Only once I deleted the app from the iPhone's home screen and reinstalled again by running the app in the debugger did console output start working again.
