Adding (simple) HEIF support requires writing a loader plugin for gdk-pixbuf that handles the file format (e.g. by using a given decoding library) and manually assigning eog as viewer for the given file type. However, while HEIF itself is just a container, the HEIC pictures from the Apple phones use the HEVC algorithm for compressing the actual image data. HEVC is a heavily patented algorithm, which would as far as I know require Ubuntu/Fedora to pay licensing fees if they'd include it in their distributions. So I wouldn't count on HEIF/HEIC/HEVC (too many abbreviations!) support in major distributions soonish.
