How do I use opaque return types with some?

In Swift, opaque return types allow you to specify that a function will return some type that conforms to a given protocol, without revealing the exact type of the return value. This feature enhances encapsulation and makes your APIs more flexible.

Here’s a simple example of using opaque return types with a function that returns a type conforming to the 'View' protocol in SwiftUI:

func makeView() -> some View { struct ContentView: View { var body: some View { Text("Hello, World!") } } return ContentView() }
