Well, yes and no. Basically, your script does the following:

	tell application "Xcode"
		tell active project document
			set myroot to root group
			tell myroot
				make new group
			end tell
		end tell
	end tell
	--> Same error as above

By assigning to myroot, it could well be that some evaluation/dereferencing occurs; let's thus try without the assignement:

	tell application "Xcode"
		tell active project document
			tell root group
				make new group
			end tell
		end tell
	end tell
	--> New unnamed group is created

In the same vein, should you really need the intermediate variable:

	tell application "Xcode"
		tell active project document
			set myroot to a reference to root group
			tell myroot
				make new group
			end tell
		end tell
	end tell
	--> New unnamed group is created

HTH,
Axel
