I'm playing arround with Xcode (for iOS) and added a View Controller to my Storyboard. Now I've created a Class (File -> New File -> Objective-c Class) and made that a subclass of UIViewController. Now the .h and .m files are generated and listed on the left side in Xcode, but when I want to change the "custom class" of my added View Controller there is nowhere my class which I had generated. Am I doing something wrong?
Thanks in advance.

In general, it's safe to assume that the “Cannot find '…' in scope” refers to a variable, function, type or other symbol that doesn't exist. If you want to solve this error, and fix the bug, start with what doesn't exist and work your way from there (i.e., text).
To generate the class and properties files initially: From the Xcode menu bar, choose Editor > Create NSManagedObject Subclass. Select your data model, then the appropriate entity, and choose where to save the files. Xcode places both a class and a properties file into your project.
The . h is called the Header file and the . m is called the Implementation file. Together, they form the AppDelegate class.
ViewController. h/m define a view controller class that manages a hierarchy of views -- basically, one screen of an application. You might have multiple screens that each have their own view controller. AppDelegate. h/m define a class that manages the application overall.
I've had the same problem. Quitting and opening Xcode will make the Class show up in the list.
edit: I've also recently found pasting the Class name will work in 5.02 Xcode.

I had the same problem. But I discovered that I was clicking inside the "window of storyboard" and was selecting a view, so with no viewController related to. My solution was: to click inside the owner, or the viewController from the left list, and then change the custom class.
