Task.sleep(seconds:)

Task.sleep.swift

extension Task where Success == Never, Failure == Never {
  /// Suspends the current task for at least the given duration in seconds.
  /// Throws if the task is cancelled while suspended.
  /// - Parameter seconds: The sleep duration in seconds.
  static func sleep(seconds: TimeInterval) async throws {
    try await Task.sleep(nanoseconds: UInt64(seconds * 1_000_000_000))
  }
}

Awesome! Thanks.

That the default .sleep func throws is confusing to me... so I simplified my implementation to:

extension Task where Success == Never, Failure == Never {
  static func sleep(seconds: TimeInterval) async {
    try? await Task.sleep(nanoseconds: UInt64(seconds * 1_000_000_000))
  }
}

This way I'm able to call without try:

await Task.sleep(seconds: 4)

@maxhumber an honest question: why is confusing to you that the function throws?

Failure == Never?

Obviously we can just do this:

try? await Task.sleep(nanoseconds: 4_000_000_000)

But the try? is kinda blahhh

@maxhumber it's up to you to decide if you want to handle errors or ignore them with try?. If you use try? — you're blocking the mechanism Swift uses to cancel asynchronous tasks, you can read more about it in the documentation in the "Task Cancellation" section https://developer.apple.com/documentation/swift/task#3925721
