Any updates about this? I'm facing the same issue on a app setting we have used successfully in the past.

I do not see the default GPX icon. There was another App Icon. This App was Installed long ago. I have installed "Avenue-GPX-Viewer" from app store to see if this may solve the issue, since then the icon is dynamic and I get a quick view. But this did not solved my xcode problem. On another computer the gpx is still working and there is no extra file type attributes. Is there a proper way to reset the global gpx file type? _kMDItemDisplayNameWithExtensions = "OfficeZurich.gpx" kMDItemContentType = "com.topografix.gpx" kMDItemContentTypeTree = ( "com.topografix.gpx", "public.xml", "public.text", "public.data", "public.item", "public.content" ) kMDItemDisplayName = "OfficeZurich.gpx" kMDItemFSName = "OfficeZurich.gpx"
