Is anybody else having significant new problems with Xcode 4.6.2 (the latest version which was released in the last few days.) I am getting hangs that require a force quit of Xcode, more crashes, problems with breakpoints breaking on the wrong lines, odd errors about prefix files being built on the wrong branch, and a whole host of other problems. Xcode 4.0 was a mess when it was first released, and for the most part it has been getting slowly more stable with each new release. This release seems to be a step backwards however. What are other people's experiences?
