It works with the Apple Books app on my iPhone. You must have a rather old iOS device.

I'm assuming that you're referring to
com.apple.ibooks.display-options.xml. That file can't be edited in Sigil, but it never needs to be edited anyway.

That's true, however, Apple seems to prefer epub3 books. BTW, you can convert epub2 books to epub3 books both with Calibre and Sigil.
If you convert your book to an epub3 book, you'll need to add
<meta property="ibooks:specified-fonts">true</meta> to the content.opf file. You'll also need to add the
ibooks namespace to the
<package> tag.
For more information, see the
Apple Books Asset Guide.
