please consider in your answer the following:
I 'm putting a break point for all exceptions
I tried to put an empty view controller and made it
the initial view controllerin order to know if the problem is in the storyboard but it crashes alsoI removed the app from the iPhone device and made clean/build but with no mean
I removed all app derived data and made clean/build but also with no mean
the provisioning profile is ok
and the following is the log when i tried it on the simulator:

thanks in advance.
Make sure that your target has the correct name entered for your storyboard file. I was able to reproduce your error by going to the Info.plist file for my target, and renaming the storyboard so it didn't match the actual storyboard filename. My guess is either you accidentally renamed that in your target or you changed the filename of your storyboard at some point.
This could happen if your application uses embedded binaries, but you haven't added them in Target > General > Embedded Binaries.
I was having a similar strange problem. The app would crash before didFinishLaunchingWithOptions, as you said. I tried some of the suggestions related to making sure the storyboard file is correct in the plist, and is properly selected for the target.
My problem was that I was referencing a font in my plist that did not exist. I had changed fonts, and forgot to change it in my plist.
