I'm migrating a GUI-application from XCode 3 to XCode 4. The source-code is only AppleScript. When I'm opening the a NIB-file the following message pops up:
AppleScript data is not supported in Xcode. The AppleScript data in this NIB file has been removed.
When I start the application its main-window just stays blank.
What can I do about this? I want to be able to edit my application, its GUI in XCode 4.5 and build it there.
Here's a screenshot of the message-box:
