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()
}
