I get the purpose of the betas (Xcode 11, iOS 13 etc) is to build and test for when iOS 13 is released.At what point should I stop developing for iOS 12 and switch to the betas?Example, if I'm planning to publish an app in June 2019 then should I use Xcode 10 and design for iOS 12? Or will anything I build in Xcode 11 for iOS 13 also work in iOS 12 and therefore I can switch to the betas now?Thanks in advance.
