Deleting/Removing Group in Xcode

Question

I seem to be having a very odd problem with my iPhone project in XCode4.

By accident, I seem to have dragged a new group I created out of my main project group:

When I try to move the group back into the project group, XCode crashes. When I try to delete the group by dragging it to the trash can, no such luck either. Is this because it's an iPhone project, and I somehow have messed up the entire directory of groups?

Answer 1

I figured it out. I had this empty group or folder whatever it is (let's call it "stubborn group") at the same level than my project. I wasn't able to delete it since the option was disable when I right clicked on it.

This is how you can remove the "stubborn group"

1. Right click on your project and select "New Group from Selection" This will create a new group named "New Group" and put your project in it
2. Now drag your project outside of "New Group" to the top (not inside) of the "Stubborn group"
3. Next is to highlight both groups and "Delete"

Answer 2

Not even the "delete button on my keyboard" was working for me. I edited the ProjectName.xcodeproj/project.xcworkspace/contents.xcworkspacedata file to remove the Group element. Xcode4 noticed that the file was changed by another application, asked if I wanted to keep the change, and closed the project. I re-opened the project and the group was gone.
