My Xcode 4 Documentation is stuck at the screen below:
This same thing happened after I updated Xcode a couple of weeks ago. Apparently I need to login, but there is no way to do so within Xcode's embedded browser.
Has anyone else experienced this?
I had the same problem. To solve, I had to re-download the documentation. Press ⌘ + , then go to the Downloads tab and download it from there.
