Bad buggy new release

This new release of XCode has been released by far too early. It is not mature, and has many severe bugs or annoying problems.
Examples :
* Can’t read old XIB files without crashing - worse, as you re-start, XCode will try to read this same XIB file that made it crash and… crash again. The only solution to get out of this crashing loop is to remove the XIB file from its folder in the finder so that XCode don’t find it any more
* Over flooding the console with XCode internal messages. This is making your real NSLogs into tons were useless information.
* Some framework don’t work at all any longer, such as CNContact (mac OS only, iOS is OK). Any access to the CNContact store returns a nil CNContact.
And many ohters...

The best advice I can give is to wait for 8.1...
