iOS [HELP] with simple iOS app!

[Oneill]

I started programming a simple apps for iOS devices after I finished 90% of objective c basics (Im still learning though).
I added on the interface builder one label,textfield and button I ran it once then after 1-2 hours I tried to run it once again I got this message:

*I doubt the code is well written since I wrote the same as the lynda.com tutorial video.
perhaps you have any clue what causes crash of the "app"?
thank you

You need to turn on automatic exception breakpoints, so that you can get a better idea of what is going wrong before you are past the point of the exception. Google exception breakpoints in xcode to figure out how to turn these on. This will allow you to give us more information about the crash

You can try to make clear the project(Product/Celan), especially if you use CoreData and change the data model.
