- 3. ✓ Create iOS, tvOS, watchOS apps ✓ Access all native iOS features ✓ Edit Storyboards and XIBs ✓ Build, test in simulator, debug ✓ Also use Xamarin.Studio on OS X
- 10. ✓ demo: To9o
- 11. ✓ Quick Actions ✓ Peek & Pop ✓ Pressure Sensitivity
- 12. ✓ CoreSpotlight ✓ NSUserActivity (Handoff & Siri)
- 13. ✓ AddressBook deprecated ✓ Contacts (create/edit) ✓ ContactsUI (read)
- 14. ✓ STACKS (horizontal & vertical) ✓ Leading/Trailing (not Left/Right) - great for localization
- 15. ✓ Right-to-left support ✓ Including UINavigationController ✓ UIStackView! UITextAlignment.Natural; Leading & Trailing v Left & Right
- 16. ✓ Re-ordering now super-easy CanMoveItem (view, index) MoveItem (view, source, dest)
- 17. ✓ Slide Over ✓ Split Screen (true multitasking) ✓ Picture-in-picture
- 19. ✓ how it works…

- 21. Shared C# codebase • 100% native API access • High performance iOS C# UI Windows C# UIAndroid C# UI Shared C# Code
- 22. Mono .NETMono iOS C# Windows C#Android C# 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) Shared C# Code • Business Logic • Database (SQLite) • Web services • File operations UIKit PassKit etc SQLite NSUrlSession file system etc native UI iOS CocoaPods Obj-C libs“bindings”
- 23. 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.
- 25. ✓ so why would I?
- 26. C# Now Runs on 2.6+ Billion Devices
- 27. Mac iOS Android Windows Phone iCircuit Touch Draw 86% 14% 72% 28% 70% 30% 61%39% 88% 12% 76% 24% 90% 10%
- 28. Traditional Xamarin Approach With Xamarin.Forms: More code-sharing, still all native iOS C# UI Windows C# UIAndroid C# UI Shared C# Backend Shared UI Code Shared C# Backend
- 31. ✓ demo: Todo (Xamarin.Forms)
- 33. ✓ one more thing…

- #22: UI build natively per platform, leveraging C# C# + XAML C# + XML C# + XIB One shared app logic code base, iOS, Android, Mac, Windows Phone, Windows Store, Windows
- #23: UI build natively per platform, leveraging C# C# + XAML C# + XML C# + XIB One shared app logic code base, iOS, Android, Mac, Windows Phone, Windows Store, Windows
- #24: There is no compromise on performance. Xamarin apps look and feel native because they are native.

- #28: iCircuit is made by Frank Krueger, a long time Mono & Xamarin developer. Sharing code lead to 70 to 90% code reuse across platforms speeding up development Real-time circuit simulator and editor used to design analog and digital circuits http://praeclarum.org/post/42378027611/icircuit-code-reuse-part-cinq
- #29: We see here the Xamarin approach we talked about earlier This enables you to be highly productive, share code, but build out UI on each platform and access platform APIs With Xamarin.Forms you now have a nice Shared UI Code layer, but still access to platform APIs You can start from native, pick a few screens, or start with forms, and replace with native later
- #35: Take test scripts and test again thousands of physical devices! All Xamarin subscribers get free device time! Check store.xamarin.com for details.
