If Apple modifies the look of platform user interfaces, I'm guessing that SwiftUI will play a huge part in a successful transition.
One of the main points of using the framework is that you are no longer burdened with basic layout and behaviors. A Toggle() is a concept, not a presentation.
In theory, your SwiftUI code & design should move as easily between iOS 18/19 as it does between iOS/watchOS.
Those of you who have been digging around in UIKit to accomplish things will have regrets.
