Too many bugs and lack of some basic features

This release of XCode contains too many bugs and lacks of features…
- Project doesn’t re-open correctly (no files on the left navigator, bad syntax and references on the files opened), force us to close and open again the project.
- When you select an item on the interface builder, the item is not set as selected on the properties editor or you cannot move with the arrows keys… I select the item like a button or other directly, it said that there is nothing selected. Thanks to this bug, I realized that I can modify the file as text and increase a frame...
- You can’t do basic things… I dont even know if it is possible to duplicate a line without selected them, copy, paste… And some awesome plugins who do this, doesn’t work when XCode is updated.
