Make sure to read my article on TaskGroups before exploring this project: Task Groups in Swift explained with code examples.
This project demonstrates how you can use a @resultBuilder in combination with TaskGroup.
let photoURLs = try await listPhotoURLs(inGallery: "Amsterdam Holiday")
let images = try await withThrowingTaskGroup {
for photoURL in photoURLs {
Task { try await downloadPhoto(url: photoURL) }
}
}Or:
func taskGroupExampleThree() async {
let names = await withTaskGroup {
Task {
await asyncOperation(name: "Antoine")
}
Task {
await asyncOperation(name: "Maaike")
}
Task {
await asyncOperation(name: "Sep")
}
}
print("Received: \(names)") // Received: ["Antoine", "Maaike", "Sep"]
}
