ComponentOne Xamarin.iOS is a collection of iOS UI controls developed by GrapeCity. Xamarin.iOS Edition has been optimized for iOS development. For existing Xuni users, the new architecture brings many new features listed below:

• Enhanced performance
  The new controls should generally perform better than the old controls (sometimes doubling performance). By specifically focusing on the Xamarin architecture, the controls cut out some intermediary logic and are optimized for the platform. Since they’re entirely in C#, so you can also expect a more consistent experience.
  
  
• Designer support
  The new controls should also support Xamarin’s designers for iOS and Android applications. This makes it much easier to construct your Android XML or iOS Storyboards using these controls.
  
  
• New control features
  The controls have been rethought for the new architecture with the combined experience of Xamarin, Wijmo, as well as ComponentOne controls. Some controls have a number additional features (such as FlexGrid).
