Xcode was not found, Please specify it

I am new to Sencha and I am running KitchenSink in Sencha. But I am getting an error "Xcode was not found, Please specify it".

I have updated Sencha and installed everything but not able to get through this error. And I am not able to find to mention xcode path or else.

Solution

Actually I was having 3 Xcode of different version. Therefore I set the path for my usable Xcode in terminal. Thats all.
