Thank you for writing. Here are the answers to your questions:
(a) As discussed in this blog article
, Telerik UI for Xamarin
is updated to support the Unified API, hence you are able to develop 64-bits apps with our product.
(b) You do not have to obtain a license for UI for iOS in order to use UI for Xamarin.iOS bindings. These bindings are included in the DevCraft Ultimate license and they do not need an additional Telerik product in order to work in your Xamarin.iOS apps.
The current thread is in the AppBuilder section, so in case you have more questions about our Xamarin offering, I would kindly ask you to address them in the appropriate UI for Xamarin forum section
. This will allow those interested in the topic to find the thread more easily.
