I want to observe/capture logging from my iPhone app when its not running via Xcode. However when using either the Mac's console app, or the console functionality within Apple Configurator, after about 2 or 3 seconds the logging disappears off the console. How can it be prevented from doing so?
I just tried it and cannot reproduce the issue that Console.app stops showing logs. It continue to stream them for me. The oldest ones scroll out at the top of the window once the windows content area fills up. But you can just scroll to them again, so I assume that's not the issue you are seeing?
An alternative to using Console.app is using Instruments.app.
Instruments should show you a lot of the same logs that Console.app showed you, but also grouped by subsystem.
I have exactly the same issue. Logs disappear after a few seconds and I can't scroll back to them.
I have the same problem, previous logs from iPhone in the Console.app disappear after some time as logs arrives.
