Xcode Setup for Catalyst Development

How are people setting up their machines to develop with Catalyst? I tried to build my iPad app for Mac using Xcode beta 11 on Mojave but it seems to want Catalina to build. So I created a Catalina boot disk using an external flash and boot into it. I installed Xcode 11 beta and tried building but I get the following message : “Your account already has a signing certificate for this machine but it is not present in your keychain. To create a new one, you must first revoke the existing certificate” .


I need to develop my current iPad app and build a Catalyst version in parallel. How can I set this up on a single machine?

I believe this is a (repeating) bug (?) in Xcode. Do -not- revoke/delete any certs. Instead, confirm on Cat/Xcode 11b that the mac is allowed as a device/dev machine, and be sure you're using the same user account, not a different one.

Further discussion might be better suited in the catalina beta forum.
