Created New Project and click on storyboard Xcode 5 crashes

Question

Tried cleaning, restart and reboot did not work.

Answer 1

XCode 5 has several "occasionally hangs" which bug fixed in letter version (Xcode 6 or Xcode 7)

So, it is better to upgrade your Xcode to Xcode 7.(may need to update mac OS X )

Or, uninstall and install your again your xcode

or, disable autolayout and try again

Answer 2

I have switched to xcode 6 ; problem solved; thanks everyone for your valuable inputs.
