I don't want to discredit anybody, but we (well, I) have no clue what was the app like. From the sound of it, it could have been a text box filled with names and addresses on a white background, and this can be achieved by dragging and dropping in the Interface Builder.

Even if that is the case, there still is a point. Developing for iOS (or OS X for that sake) has been made easy. Just fire up Xcode and start typing. Contrary to Android platform a year or a two ago (last time when I checked it out), many more clicks and bits were needed before actual code could be written.
