+        This repository hosts the Swift compiler, the Swift standard library,
+        the Swift runtime, SourceKit, and IDE support for the Swift language.
+        It does *not* track issues with or requests for Xcode and other
+        closed-source Apple software such as SwiftUI and UIKit; please direct
+        them to
+        [feedbackassistant.apple.com](https://feedbackassistant.apple.com)
+        instead.
+  - type: textarea
+    attributes:
+      label: Description
+      description: >
+        A concise description of what causes the problem, in human language.
+        Though not required, it may help us to more accurately triage the issue
+        as well as understand a non-trivial test case.

+    attributes:
+      label: Reproduction
+      description: >
+        Provide a test case, preferably in a Markdown codeblock, and explain
+        how to build or run it to reproduce the problem. Consider reducing the
+        test case to the smallest amount of code possible — a smaller test case
+        is easier to reason about and more appealing to contributors.
