While writing this, we are at the latest version of VS 2019, Mac OS and the latest stable Xamarin Forms.
We've tried the "clean and rebuild", "restart VS", "reboot the Mac", "reboot Windows" and even "reinstall Mono/Xamarin on the Mac by uninstalling it, reboot and let VS install Mono/Xamarin on the Mac".
The Android and UWP projects run normally. It started while the Mac was running 10.14, but as one of the attempts to fix the issue, we've updated it to 10.15. This goes for both simulators and actual devices.
Last week, without any real cause, the iOS builds started to fail. We're working on a long term project, starting at Xamarin 2.x and upgraded it every step of the way.
Hard to describe how to reproduce this issue. In a nutshell: we cannot debug our iOS app at all, as "the client has been disconnected while waiting a post response to topic.
