SE-0328 widens the range of places that opaque result types can be used.
For example, we can now return more than one opaque type at a time:
import SwiftUI
func showUserDetails() -> (some Equatable, some Equatable) {
(Text("Username"), Text("@twostraws"))
}
We can also return opaque types:
func createUser() -> [some View] {
let usernames = ["@frankefoster", "@mikaela__caron", "@museumshuffle"]
return usernames.map(Text.init)
}
Or even send back a function that itself returns an opaque type when called:
func createDiceRoll() -> () -> some View {
return {
let diceRoll = Int.random(in: 1...6)
return Text(String(diceRoll))
}
}
So, this is another great example of Swift harmonizing the language to make things consistently possible.

Build your interface in a completely visual canvas, then drag and drop into your Xcode project and wire up button clicks to custom code. Download the Mac App and start your free trial today!
