Please have a look of SwiftUI known issue

Known Issues

  • Previews may fail or update incorrectly when switching between files. (50841287)

    => Workaround: Add a newline to the end of the active file, then click "Resume" in the banner that appears.

  • watchOS previews might fail if you select a physical phone that’s paired with a watch as the run destination from the Scheme pop-up menu. (50861269)

    =>Workaround: Select a watchOS simulator while working with previews.

  • Previews don’t appear in the canvas for private and fileprivate structures that conform to PreviewProvider. (47011316)

    => Workaround: Remove the private or fileprivate access control from your conforming type.

  • Previews might take several seconds to update when switching devices in the run destination selector the first time. (47562171)

  • Previews might temporarily show the incorrect device chrome when switching devices using the run destination from the Scheme pop-up menu. (49496647)

  • The canvas doesn’t support focus. (50275735)

  • Undo is unavailable in the canvas. (49651153)

    =>Workaround: Bring the source editor into focus and perform the undo there.

  • The insertion indicator only shows on the topmost item for repeated content such as content in a List or ForEach view. (50244112)

  • Xcode 11 beta doesn’t support working with SwiftUI in a project configured to use UIKit for Mac.

  • When you launch Xcode on macOS 10.15 beta, the required packages installer might display erroneously. (51080815)

Note:

I know, Everyone wants to work with a new layout design pattern but still, SwiftUI framework is not stable.
