How to see the javascript errors of PhoneGap app in Xcode?

Question

I want to debug my PhoneGap app in Xcode, but its Console can not show javascript errors.

Answer 1

debug.log will send messages to the XCode console in Phonegap (allowing you to either log the result of an exception or do some debugging), however, you are correct that you have to debug other javascript errors in Safari (either on the desktop or on the iphone with Debug Console turned on). I have yet to find a Javascript error, that was caused by running on the iphone and wasn't present when debugging with the console turned on in Safari (though I know there are a few differences between the WebView and Safari on the iphone).
