Xcode Error : Code Object is not signed at all

Hi,

Recently figured it for first time while developing a Mac App.

I assigned the development team and certificate in Xcode, the bundle identifier was also properly set.
Build the app and the Error pops up

Code Object is not signed at all

Searched and finally found : --deep
Yes exactly, add this value for Other Code Signing Flags under Target's Build Settings tab

Build and Run
And BINGO

Happy Coding :)
