For sending files between my phone (Android) and my son's iPad, I use:

Wormhole William (Android): https://github.com/psanford/wormhole-william-mobile

Destiny (iOS): https://github.com/LeastAuthority/destiny

For interoperability, don't use Destiny's default servers. After you install Destiny, change the config to the standard Magic Wormhole servers:

Mailbox: ws://relay.magic-wormhole.io:4000/v1

Transit Relay: tcp://transit.magic-wormhole.io:4001
