+* [IpfConnect](https://github.com/dxFeed/dxfeed-graal-swift-api/blob/swift/Samples/Tools/IpfConnect.swift)
+    This sample demonstrates how to subscribe to available symbols using IPF. It uses a DxFeed and dxfeed.properties file
+* [LiveIpfSample](https://github.com/dxFeed/dxfeed-graal-swift-api/blob/swift/Samples/Tools/LiveIpfSample.swift)
+  This sample demonstrates how to an instrument profile URL and reads instrument profiles with support of streaming live updates.
+* [ScheduleSample](https://github.com/dxFeed/dxfeed-graal-swift-api/blob/swift/Samples/Tools/ScheduleSample.swift)
