I created a settings bundle for my iOS app and tried to edit the Root.plist file.
I can change some of the existing values (those that are created by default), but if I try to add a new item (no matter the type), Xcode 4 crashes with the following error:
Anybody knows what might be causing this?
I’m using Xcode 4.02 build 4A2002a.
This is the log:

This is the contents of the root.plist created by Xcode itself:

Sounds like an Apple bug. If you tell Xcode to Continue rather than Crash, you might be able to keep working as if nothing went wrong. If all else fails, you might consider using PlistBuddy or defaults to manipulate your plist. (Property List Editor.app would be ideal, but I don’t think it’s included in the Xcode 4 installation.)
