Forked to Capacitor Community

[mlynch]

Hi there,

Given this repo is not maintained and is an important part of the Capacitor developer experience, we've forked it over into the new Capacitor Community org and will be taking up maintenance, however we need community help as well, so please join us there: https://github.com/capacitor-community/apple-sign-in

@rlfrahm can you add some link in the readme to direct people to the community repo?

cheers!
