Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. The issue is that you’re using Apple’s official Swift extension (swiftlang.swift-vscode), which depends on lldb-dap that isn’t available in Cursor.

For Cursor, we recommend using the Swift Language Support extension instead. Please try:

  1. Remove the current extension: swiftlang.swift-vscode
  2. Install Swift Language Support (chrisatwindsurf.swift-vscode)
  3. Restart Cursor

Additionally, I recommend checking our Swift setup guide:

Let me know if this helps!
