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?
How do you stop logging in the console from disappearing after a few seconds?
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.
- Launch Instruments
- Select "Logging" template from the template chooser.
- Select your target device and maybe a target app (or "All Processes") from the target chooser.
- Click the record button.
Instruments should show you a lot of the same logs that Console.app showed you, but also grouped by subsystem.
