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 ?

At the moment, it appears to be enabled only up to version 4.3 of the MAC OS client lib. Therefore, it seems that the client APIs download page is indeed misleading. We are checking with IG to understand when there will be updates.
