Xcode 11 Beta SwiftUI canvas popovers not working

I'm working through the SwiftUI Essentials tutorial in the Xcode 11 Beta developer documentation, and neither the canvas, nor the popover menus described in the documentation are appearing.


I'm running Mojave with the latest updates. Am I missing something? Do I need to also be on the Catalina beta as well?

Nevermind. I just read that you have to be on the Catalina (10.15) beta. 😟

I understand the live preview not working, but the popover menus should be fully functional. I will have to wait. I am not ready or able to load Catalina on my Mac. 😟

Oh, man! I was so excited testing this out. Not able to install Catalina at the moment.😟
