Today I learned that you can actually create multiple Xcode screen previews in SwiftUI. Assuming you have a SwiftUI View named ContentView. In the PreviewProvider, create a Group and init multiple ContentView() children inside of it. For example: struct ContentView_Previews: PreviewProvider { static var previews: some View { Group { ContentView() .previewDevice(PreviewDevice(rawValue: "iPhone 11")) .previewDisplayName("iPhone 11") // Optional ContentView() .previewDevice(PreviewDevice(rawValue: "iPhone 8")) .previewDisplayName("iPhone 8 Dark") .environment(\.colorScheme, .dark) .environment(\.sizeCategory, .accessibilityLarge) ContentView() .

Did you know that SwiftUI can be use in UIKit project? To use SwiftUI in UIKit project, you have to make use of UIHostingViewController. It is a UIViewController that basically “host” a SwiftUI view. Assuming you have a SwiftUI View named SwiftUIView like so: let swiftUIView = SwiftUIView() Initializing it programmatically To initialize it programmatically, set the SwiftUI View as the rootView of the UIHostingController. let vc = UIHostingController(rootView: swiftUIView) self.
