Xcode Preview fails to preview a view on a real device

I have a simple SwiftUI view with a few content and want to preview it on a real device, but the preview will fails and gives 'BSServiceConnectionErrorDomain error 3' error.

I'm using iOS 14 beta 3 and macOS Catalina 10.15.5 with Xcode 12 beta 3. I've been getting that error since the first beta of Xcode 12, hoped to be fixed in the today's Xcode beta, but it was not.
I'm getting this problem too. I guess you have to wait for the next beta.
