Somewhat days ago Apple released a new version of XCode, and a lot of stuff is new in this version. Thereby also the layout of the application, interface builder and the way an application can be constructed.
But, for those of you completely new to development for iOS devices (and for those of you new to XCode 4 or for you who just want to shape up a bit? =S), I wrote a Hello World for XCode 4, iOS4.3.
So, lets get started.
