 ### Fixed
 
 - Fixed stderr warnings (e.g. "multiple matching destinations") hiding actual test failures by prioritizing xcresult output when available ([#231](https://github.com/getsentry/XcodeBuildMCP/issues/231))
+- Fixed `swift_package_build`, `swift_package_test`, and `swift_package_clean` swallowing compiler diagnostics on failure by treating empty stderr as falsy, so stdout diagnostics are included in the error response ([#243](https://github.com/getsentry/XcodeBuildMCP/issues/243)).
