Problem when running the App

After fallowing all the steps, when run the program and click on the button...: the app shows me the top_level_code, and highlights the line: class AppDelegate: UIResponder, UIApplicationDelegate {

Can anyone help me with that one?

Thank you.

you probably have an exception being thrown, check the console for an error message and post what you find

Hi Bruno, I am encountering the same error as you. Did you figure out how to get past this error?

Thanks,

Hi Bruno,

We could do with seeing what error is being shown in Xcode - can you copy the contents of the console, as Stone suggested?

Steve.
