Apple today put out a minor bugfix upgrade to Xcode, now bringing the company's Mac OS integrated development environment to version 4.2.1. The update fixes a malfunctioning conversion operation, resolves an issue of "missing" developer profiles, and squashes a bug showing a locked file dialog where it shouldn't be. The updates adds to the improvements added to Xcode 4.2, which was updated a little more than a month ago.
