-Xcode generates test results in a plist (property list) file format. It is possible to convert a plist file format into an XML format that can be uploaded to CircleCI using the `xsltproc` command. Follow the steps in this link:https://medium.com/@warchimede/convert-xcode-plist-test-reports-to-junit-xml-6f0aa8c3fa58[third party resource] to convert the file and then use `store_test_results` to upload the results to CircleCI.
+Xcode generates test results in a Xcode Test Results (`.xcresult`) bundle format.
+
+To integrate with CircleCI's test results features you will need to convert your Xcode Test Result bundle to the JUnit XML format.
+
+To convert your Xcode Test Result bundle you can use a third party tool, for example, link:https://fastlane.tools/[Fastlane] or link:https://github.com/xcpretty/xcpretty[xcpretty]. Once your test results are converted you can use `store_test_results` to upload the results to CircleCI.
