When I debug an app on my iPad, it's often the case that when I get back to it after some time has passed, the debugging session has already stopped but the app is still running.
It's very frustrating because I specifically baked some UIWebView debugging tools into the app like reloading external content on a swipe so I don't have to recompile it every time I change something.
I've looked at the settings and found nothing like “debugging timeout”. What's the matter?
It turns out, the problem was in Auto Lock.
It unloads the application, and thus soft debugger's connection is lost.
Setting Auto Lock to 15 minutes solved my problem.
