Thank you for your post and your screenshot. While the screenshot depicts the app as a SwiftUI View, your post explicitly mentions that the app is built using UIKit Storyboards? When utilizing Xcode Previews with a storyboard-based macOS application that retains the default window controller entry point, it is important to note that the app’s entry point is typically defined by a window controller in the storyboard (often linked to the initial scene). In full-screen mode, macOS may preserve this state across UI refreshes. Could you please isolate the entry point of the app and create a new focused project that displays it? Additionally, I recommend providing your expectations so that we can assist you in fulfilling them. If you intend to use SwiftUI, I would suggest sticking to that framework. Albert Pascual
