Thank you Giuseppe ! I managed to setup version 4.3.3 from this page : https://github.com/Lightstreamer/Lightstreamer_macOS_Client And with a bit of tweaking, it works. It's sad that the official page is misleading. I hope they'll fix it or update the servers.

Yes as a first step I've setup a proof of concept with a call to push.lightstreamer.com and it works just fine.

Still trying to make a proof of concept running on Mac OS Swift with IG. I'm using the 5.0.3 version of the Lightstreamer client as recommended but got this error after a successful connexion : Disconnected. Cause: 60 - License not valid for this Client version I tried 5.0.0, 5.0.1, 5.0.2 and got the same error, I can't downgrade any further. Here is the full logs : Status: CONNECTING WS connecting: https://apd.marketdatasystems.com/lightstreamer Sec-WebSocket-Protocol: TLCP-2.4.0.lightstreamer.com apd.marketdatasystems.com is reachable WS event: viabilityChanged(true) WS event: connected(["Sec-WebSocket-Version": "13", "Upgrade": "websocket", "Date": "Mon, 8 Apr 2024 09:00:40 GMT", "Server": "Lightstreamer Server", "Sec-WebSocket-Protocol": "TLCP-2.4.0.lightstreamer.com", "Sec-WebSocket-Accept": "706gGJ8aNnzq3IHoTdtYS4mz874=", "Connection": "Upgrade"]) Sending session create: [LS_user=XXXX, LS_cid=scFuxkwp1ltvcB4BJ7Ji kOj2DK6P7C3jk, LS_send_sync=false, LS_cause=api] WS sending: "wsok" WS sending: "create_session\r\nLS_user=XXXX&LS_cid=scFuxkwp1ltvcB4BJ7Ji%20kOj2DK6P7C3jk&LS_send_sync=false&LS_cause=api&LS_password=CST-1fa5b29b51e068feae2adb5a6630e6dc6912b1dc7a27b6ea8b67ee402b6a92CC01113%7CXST-e1fd796ddce452c263ef65257bf9060d7b97692c706b90b57ae99848a357bfCD01113" WS event: text("WSOK\r\n") WSOK WS event: text("CONERR,60,License not valid for this Client version\r\n") CONERR 60 License not valid for this Client version WS disposing Status: DISCONNECTED Disconnected. Cause: 60 - License not valid for this Client version Which version of the Lightstreamer SDK is supported by IG servers ?

Found the origin of the problem. The client variable was a weak reference and garbage collected before the connexion had a chance to succeed. Beginner mistake...

I'm certainly missing something obvious but I can't figure it out. I'm trying to get the lightstream sdk to work on a macOS project in swift Everything compiles perfectly and runs without errors but the log systematically indicates Status: CONNECTING The same code in Javascript works just fine. LighstreamerClient is version 5.0.3 as recommended. Here is my code let loggerProvider = ConsoleLoggerProvider(level: .debug) LightstreamerClient.setLoggerProvider(loggerProvider) let client = LightstreamerClient(serverAddress: lightstreamerEndpoint) client.connectionDetails.user = currentAccountId client.connectionDetails.setPassword("CST-\(cst)|XST-\(securityToken)") client.addDelegate(ClientDelegateImpl()) client.connect() And the log : serverAddress changed: https://apd.marketdatasystems.com user changed: XXXXX password changed Connection requested: details: [serverAddress: https://apd.marketdatasystems.com, user: XXXXX, libVersion: swift_client 5.0.3] options: [requestedMaxBandwidth: unlimited, retryDelay: 4000, firstRetryMaxDelay: 100, sessionRecoveryTimeout: 15000, stalledTimeout: 2000, reconnectTimeout: 3000, idleTimeout: 19000, contentLength: 50000000] Status: CONNECTING WS connecting: https://apd.marketdatasystems.com/lightstreamer Sec-WebSocket-Protocol: TLCP-2.4.0.lightstreamer.com Does anyone have an idea or managed to get the SDK to work with IG on swift?
