phono-ios broken and abandoned

[hydrajump]

It is a real shame that the Phono iOS native libraries and example project are no longer maintained!

I've tried to get the sample app VisIVR working and even chatted with @steely-glint, but the libraries fail to build and/ or are not found due to incorrect paths in the Xcode projects.

It is unfortunate, as I have not been able to find an alternative that is easy to use and open-source for implementing voice calling on iOS.
