[tjprescott]

🚨New Issue Checklist🚨

• Updated swift-ast to the latest version
• I am aware that the swift-ast -github-issue /path/to/file.swift might help me generate this file

Issue Summary

Environment

• OS Info: [Please insert the operating system name and version]
• Yanagiba/swift-ast version: [Please insert the swift-ast version]

Reproduction Steps

Try to parse:
class SomeClass: @unchecked Sendable

It will fail due to the @unchecked attribute. It doesn't seem the swift-ast type inheritance parser accepts attributes.

Command to run swift-ast with the code above:
swift-ast sample.swift

Even Better

Is your project open sourced? If yes, can you point us to your repository?
If not, is it possible to make a small project that fails the Travis CI?
If not, can you create a gist with your sample code for us?

Since this hasn't been updated since 2019, no, this definitely isn't solved in the latest version.
