Add Swift Testing Attachments For Better Failure Reports
Read OriginalThis article explains how to use the Swift Testing framework's Attachment API in Xcode 26 to improve test failure diagnostics. It covers recording text, JSON payloads, and images as attachments that provide context when tests fail, especially for tests involving generated output, server payloads, or image rendering. The article includes code examples for attaching strings and conditionally recording data only on failure, helping developers debug more efficiently in CI environments without needing to re-run tests locally.
