Description

When there is an SDK mismatch, sourcekitd silently fails

Steps to Reproduce

  1. Have a tasks.json entry that points to an SDK from one Xcode installation
  2. Build that task
  3. Configure the SDK in settings to points to an SDK from a different Xcode installation
  4. Reload the window
  5. Next time sourcekit-lsp starts, no IntelliSense is available
  6. Open the output channel and should see an error like this
2024-11-05 13:32:44.195827-0500 0x47bb1    Error       0x0                  29814  0    sourcekit-lsp: [org.swift.sourcekit-lsp:request-26] Received sourcekitd response:
error response (Request Failed): Loading the standard library failed

To be clear, SourceKit does not crash here, it just fails. But the end result looks similar to the user.

The missing diagnostics might be due to an error that the user can fix. Report it to them.
