Hi Marcel,
Greetings from Syncfusion, we have just recently launched our Volume 3 Beta release 16.3.0.17 in NuGet.org, you can refer "Syncfusion.Xamarin.Core" assembly to use this control. We have also planned to rollout our main release at the end of September 2018. We have prepared a simple sample to showcase this control and it can be downloaded from the link below.
Hope this helps.
Thanks,
Michael
