IPhone App Build Successful But nothing shows

Very new to Iphone development here, I have a project which is successfully building (which is a first for me :) It loads the simulator but it just closes as soon as it load开发者_开发知识库s, how can I debug this? It appears the Interface Builder xib files are not loading, I've added a xib thats from a hello world project, (they have different project names) Is this an issue?

Any advice would help, Thanks!

You probably have an error in the Debugger Console. If it has to do with the XIB, it could be that you simply got the name wrong.

Another simple mistake is trying to use Outlets before viewDidLoad is called (for instance, in init).

In either case -- the message in the console will help.
