I have an iOS 13 app that I’m hoping to release soon that is written entirely in SwiftUI. If I was starting from scratch today, I’d obviously use the new multi platform template which looks awesome.... But since I’m not starting from scratch, what are the recommendations/best practices for existing apps? Is there a path for migrating existing apps to take advantage of the new app structure (below) when moving to iOS 14? @main struct HelloWorld: App { var body: some Scene { WindowGroup { Text(“Hello, world!”).padding() } } }
