+# Swift XCUITest example
+
+This example runs passing UI tests against a minimal iOS app and uploads the
+results with [`test-collector-swift`](https://github.com/buildkite/test-collector-swift).
+It uses a shared scheme, a lexical test plan, and an explicit `.xcresult`
+bundle so the same command works locally and on a macOS Buildkite agent.
+
+Run it with:
+
+```sh
+bin/test
+```
+
+The script selects the first available iPhone Simulator. Set
+`XCUITEST_DESTINATION` to pass a different `xcodebuild` destination.
