While working in Xcode's new storyboard view (Xcode 4) you may find yourself mysteriously looking at some xml, instead of the normal GUI-like view. Don't panic. You are looking at the source code view of your storyboard.

Simply right click on your storyboard file in the navigator view (left-hand side of screen). And open as the Interface Builder - iOS Storyboard.

1. Right click on file
2. Open As -> Interface Builder - iOS Storyboard
