For the most part when working with PhoneGap, debugging is as simple as loading your project’s www directory in your browser/simulator. But sometimes you need to debug the PhoneGap API calls. Well, it turns out you can… sort of.
PhoneGap has a built-in console redirect so that when you make a
call it outputs to Xcode’s Console. To view the Console within Xcode click View → Console. You don’t even need to do anything special – just Build and Run.
I say sort of because you can’t set breakpoints or the like within your JS. But console output beats the hell outta alerts.
