I am still on mojave. i am reading a few problems for xamarin developers on Catalina. Is there any know advantage to upgrade on Catalina or i should better keep it using Mojave better for a while.
XCode also supports Mac OS developing. So it's best to update the Catalina if you want to utilize the latest XCode version(11.2.1). It is also recommended by Apple as the automatic update alert for XCode always displays with the OS update.
Once the version has been released this should be a stable one and we could use the new features there. If you have updated all the tools(XCode, VS for Mac and VS) try to enjoy the latest Mac OS too.
