Hi Rodrigo,
Thanks for using Syncfusion product.
We have not changed the namespace of SfTabView in any platform in our latest versions. Please have the below namespace for SfTabView.
NameSpace:

Syncfusion.XForms.TabView

Syncfusion.XForms.Android.TabView

Assembly :
https://help.syncfusion.com/xamarin/introduction/control-dependencies#sftabview The SfTabViewRenderer will be in the platform wise namespaces [Syncfusion.XForms.iOS.TabView.SfTabViewRenderer]. We have created a simple sample using SfTabView which is available in the below link. Please have the sample and if you still face any issues please let us know the namespace you have been using and the error if any.
