Key quote from The Verge article:

When we asked Google whether it developed this feature with or without Apple’s involvement, Moriconi confirmed it was not a collab. “We accomplished this through our own implementation,” he tells The Verge. “Our implementation was thoroughly vetted by our own privacy and security teams, and we also engaged a third party security firm to pentest the solution.” Google didn’t exactly answer our question when we asked how the company anticipated Apple responding to the development; Moriconi only says that “…we always welcome collaboration opportunities to address interoperability issues between iOS and Android.”
