We are not aware with such problem with our SDKBrowser example app and with other existing apps migrated to latest version of "UI for Xamarin" suite.
Can you confirm that targeting different versions of XamarinForms NuGets/dll-s (especially the latest one 18.104.22.168), you performed a full clean of the project (including manual delete of "obj" and "bin" folders)?
Is it possible to give us more details about your setup?
Version of XamarinStudio/Xamarin plug-in for VisualStudio? (we always target latest released).
Version of the XCode installed?
iOS version of the target simulator/device, where this is observed?
Thank you in advance.
