✓ demo: To9o
✓ Quick Actions✓ Peek & Pop✓ Pressure Sensitivity
3D Touch
✓ CoreSpotlight✓ NSUserActivity (Handoff & Siri)
Search
✓ AddressBook deprecated✓ Contacts (create/edit)✓ ContactsUI (read)
Contacts
✓ STACKS (horizontal & vertical)✓ Leading/Trailing (not Left/Right) - great for localization

Xamarin’s Unique Approach
Shared C# codebase • 100% native API access • High performance

Under the Bonnet Hood

Shared C# Code
Parts of Mono being used(unused code linked away)
runs natively on iOS
• User Interface Code (C#)• Storyboards & XIBs• Platform features (eg iOS 9)

Native Performance
Xamarin.iOS does full Ahead Of Time (AOT) compilation to produce an ARM binary for Apple’s App Store.
Xamarin.Android takes advantage of Just In Time (JIT) compilation on the Android device.
Native Performance
