Using previewInterfaceOrientation results in runtime crash on iOS 14

Using Xcode 13 beta 2:

In my SwiftUI preview code I add previewInterfaceOrientation like so:

static var previews: some View {
    Group {
        Preview()

    #if swift(>=5.5)
        if #available(iOS 15.0, *) {
            Group {
                Preview()
            }
            .previewInterfaceOrientation(.landscapeRight)
        }
    #endif
    }
}

With this code and running on an iOS 14 device the app crashes immediately with dyld: Symbol not found: _$s7SwiftUI4ViewPAAE27previewInterfaceOrientationyQrAA0eF0VFQOMQ

It would seem I can't use this handy interface orientation option in Previews until the app's minimum target is iOS 15. It seems like a bug in the framework because that symbol should be considered optional as it is surrounded by if #available.
