[Swift Lightstreamer License not valid for this Client version]

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.

According to this page, 5.0.3 is correct

https://labs.ig.com/lightstreamer-downloads

IG has server version 7.3.3. Have you got the demo app working?

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

[Swift Lightstreamer License not valid for this Client version]

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 :

Which version of the Lightstreamer SDK is supported by IG servers ?

[No connexion on swift lightstream SDK]

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...

[No connexion on swift lightstream SDK]

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]

Does anyone have an idea or managed to get the SDK to work with IG on swift?
