Hi Gianluca,

The Swift Package Manager has now implemented all the requirements needed to distribute LightStreamer through SPM. You can see the new features in the Swift Evolution status page. Specifically:
- SE-273: Package Manager conditional target dependencies.
- SE-272: Package Manager binary dependencies.
- SE-271: Package Manager resources.
- SE-278: Package Manager localized resources.

These features are already implemented and can be accessed in the Swift development snapshots. They will be released to the broad public with Swift 5.3. Supporting SPM would definitely help me out managing dependencies and updating libraries. Please consider supporting SPM as soon as you can (SPM better than XCFramework).

In that same vein, boris@ig, IG could also update its Lightstreamer requirements. It seems it has been frozen in time.
