Add .ipa file (iOS app) to the releases as asset at github releases & add description of the release in:
https://github.com/flightwallet/ios/releases

Hi! This project isn't much supported right now. If you could build an .ipa, I will happily publish it, though!

For the main usecase, see WalletConnect as a replacement.
