I just had a look at this. This appears to work:

        {
            name: "High Efficiency Image File Format",
            extension: "heic,heif",
            mime: "image/heif",
            description: "",
            signature: {
                0: 0x00,
                1: 0x00,
                2: 0x00,
                // 3 could be 0x24 or 0x18, so skip it
                4: 0x66, // ftypheic
                5: 0x74,
                6: 0x79,
                7: 0x70,
                8: 0x68,
                9: 0x65,
                10: 0x69,
                11: 0x63
            },
            extractor: null
        },

Note that comment about the third byte - I found one example file with 0x24 and another with 0x18 so I skip that one entirely.

OK, thank you very much.
