Never used xcode before, using it now for ios phonegap dev. I have found that when I run in simulator I can see the logged information in the output view of xcode, which is fine as far as it goes. However, even simple syntax errors like omitted commas do not cause any visible error messages to appear during build or test run. All I get is a blank screen and I have to hunt around by eye until i find "oh yeah, there needs to be a comma after that config element". This is a painstaking way to develop.

Am I perhaps not looking in the appropriate place. I am used to developing web apps in browsers which have firebug, so I am familiar with javascript error reportage in that context. However, I cannot find anything similarly helpful in this xcode / ios simulator environment. All I can see is this error log view, which does not report much.
