Lightstreamer - Basic Stock-List Demo - macOS Client

This project contains an example of an application for Mac that employs the Lightstreamer Swift Client library.

Live Demo


View live demo

(download "StockList Demo for OS"; unzip it; launch "StockList Demo for macOS")


This app, compatible with macOS, is a Swift version of the Stock-List Demos.

This app uses the Swift Client API for Lightstreamer to handle the communications with Lightstreamer Server. A simple user interface is implemented to display the real-time data received from Lightstreamer Server.


If you want to install a version of this demo pointing to your local Lightstreamer Server, follow these steps:

  • Note that, as prerequisite, the Lightstreamer - Stock- List Demo - Java Adapter has to be deployed on your local Lightstreamer Server instance. Please check out that project and follow the installation instructions provided with it.
  • Launch Lightstreamer Server.
  • Download the file, which you can find in the deploy release of this project and extract the StockList Demo for folder.
  • Launch "StockList Demo for macOS". The Gatekeeper may signal the app is not signed. You can safely run the app or rebuild it with the included Xcode project.


To build your own version of the demo, instead of using the one provided in the file from the Install section above, open the project with Xcode and it should compile with no errors.


With the current settings, the demo tries to connect to the demo server currently running on Lightstreamer website.
The demo can be reconfigured and recompiled to connect to the local installation of Lightstreamer Server. You just have to change SERVER_URL, as defined in StockList Demo for macOS/StockListWindowController.swift; a ":port" part can also be added. The example requires that the QUOTE_ADAPTER has to be deployed in your local Lightstreamer server instance; the LiteralBasedProvider is also needed, but it is already provided by Lightstreamer server.
