# record(_:sourceLocation:) Attach an attachment to the current test. ``` static func record(_ attachment: consuming Attachment, sourceLocation: SourceLocation = #_sourceLocation) ``` ## Parameters `attachment` The attachment to attach. `sourceLocation` The source location of the call to this function. ## Discussion When `attachableValue` is an instance of a type that does not conform to the [`Sendable`](https://developer.apple.com/documentation/swift/sendable) protocol, the testing library calls its [`withUnsafeBytes(for:_:)`](/documentation/Testing/Attachable/withUnsafeBytes(for:_:)) immediately and records a copy of the resulting buffer instead. If `attachableValue` throws an error when the testing library calls its [`withUnsafeBytes(for:_:)`](/documentation/Testing/Attachable/withUnsafeBytes(for:_:)) function, the testing library records that error as an issue in the current test. --- Copyright © 2026 Apple Inc.
