Xcode 5 broke the Safari Web Inspector
So it turns out that along with the release of iOS 7 and Xcode 5, Web Inspector inside Safari has broken.
- Unable to view the DOM of your website.
- Unable to access the styles associated with your webpage.
So long as you have a free Apple developer licence, it’s a relatively straight forward fix.
You simply need to download and install Safari 6.1 from the Apple Developers portal.
Although i didn’t try this approach, apparently the Webkit Nightly build will fix the problem too, according to this thread.
