As far as I know, the biggest use of Clean Architecture in mobile is at Uber with the RIBs architecture, and it’s only applicable there because an app of that team size is closer to an enterprise Java server codebase. Most apps everywhere are not anything like that, and thus should not be using VIPER.
What's the size of the team/app? Really curious what companies out there besides Uber has used RIBS or VIPER. Not sure why they would do that either, other than it was trendy on some technical blogs back in like 2014.
