//: [Previous](@previous)

import Foundation
import AppKit

Task {
  print("[DEBUG] BEING")

  var task: Task<String, Error>?

  task = Task {
    print("[DEBUG] Start Task")
    try await Task.sleep(nanoseconds: 3_000_000_000)
    print("[DEBUG] End Task")

    return "success"
  }

  try await Task.sleep(nanoseconds: 1_500_000_000)
  print("[DEBUG] CANCELING")
  task?.cancel()

  do {
    let result = try await task?.value
    print("Result: \(String(describing: result))")
  } catch {
    print("Failure")
  }

  print("[DEBUG] END")
}
