There is a safe workaround for using Swarm code: 'inherit' by posession
--- an advice I myself neglect too often but often come back to ---:
Simply write a wrapper class, or facade, as it is called by the pattern
community.  Something like

@interface GeoLinkItem
{
        id <LinkItem> myLinkItem;
}
Linkitem methods
@end

@implementation GeoLinkItem
- method
{
        return [myLinkItem method];
}

Another example would be TextItemWithStr in (surprise) logzone-0.7
which was uploaded freshly.
