Change order of .xcdatamodel entries in .xcdatamodeld file

Yeah, this part is totally annoying - but it's not too hard. I do it all the time. You have to edit the MyProject.xcodeproj/project.pbxproj file yourself with a text editor (I use vim for this), and look for where your list of models are, then just re-order the children section, like this:

    D6A5760112F22213004DEDCE /* Scott.xcdatamodeld */ = {
        isa = XCVersionGroup;
        children = (
            D6B7528A1506A0050066268A /* Scott-V14.xcdatamodel */,
            D659922515057BC100955005 /* Scott-V13.xcdatamodel */,
            D6EDB44614ED9D7E00C02938 /* Scott-V12.xcdatamodel */,
            D6931E6214D78135007F0E03 /* Scott-V11.xcdatamodel */,
        );
        currentVersion = D6B7528A1506A0050066268A /* Scott-V14.xcdatamodel */;
        name = Scott.xcdatamodeld;
        path = Shared/Scott.xcdatamodeld;
        sourceTree = "<group>";
        versionGroupType = wrapper.xcdatamodel;
    };
