But it doesn't seem like the ones in SwiftRefactor are available neither in Xcode nor in VS Code. Will SourceKit-LSP eventually call these instead the swift/lib/Refactoring ones?
The idea is that the SwiftRefactor actions are syntactic (don’t require information from the type checker) while the ones in swift/lib/Refactoring to require type information. I think lib/Refactoring still contains a few refactoring at the moment that are syntactic because they pre-date swift-syntax.
