After updated to 6.3. When I restart Xcode, it auto reloading my working project. But it stuck with "Loading..." message.
When I try to remove userdata in the project:
Not working. Then I try to remove autosave information:
Still not working. Lastly, I try to remove the the Xcode save state
~/Library/Saved\ Application\ State/com.apple.dt.Xcode.savedState
Then Xcode will reset to default without loading previous project. After I open the project manually, everything back to normal.
