+## Tools
+
+[Tools](https://github.com/dxFeed/dxfeed-graal-swift-api/tree/swift/Samples/PerfTestCL/)
+is a collection of tools that allow you to subscribe to various market events for the specified symbols. The tools can
+be
+downloaded
+from [Release](https://github.com/dxFeed/dxfeed-graal-swift-api/releases) (tools.zip includes self-contained versions)
+
+* [Connect](https://github.com/dxFeed/dxfeed-graal-swift-api/blob/swift/Samples/PerfTestCL/ConnectTool.swift)
+  connects to the specified address(es) and subscribes to the specified events with the specified symbol
+* [Dump](https://github.com/dxFeed/dxfeed-graal-swift-api/blob/swift/Samples/PerfTestCL/DumpTool.swift)
+  dumps all events received from address. This was designed to retrieve data from a file
+* [PerfTest](https://github.com/dxFeed/dxfeed-graal-swift-api/blob/swift/Samples/PerfTestCL/PerfTestTool.swift)
+  connects to the specified address(es) and calculates performance counters (events per second, memory usage, CPU usage,
+  etc.)
+* [LatencyTest](https://github.com/dxFeed/dxfeed-graal-swift-api/blob/swift/Samples/PerfTestCL/LatencyTestTool.swift)
+  connects to the specified address(es) and calculates latency.
+
+To run tools on macOs, it may be necessary to unquarantine them:
+
+```
+sudo /usr/bin/xattr -r -d com.apple.quarantine <directory_with_tools>
+```
