Dave Ortinau: Xamarin Mobile Platform: Compromise less, deliver more

Video: https://www.youtube.com/watch?v=kAVnoKi2oLY

Speaker: Dave has been in the creative software field for 20 years. After a successful startup experience with ThisLife and Shutterfly, Dave founded Rendr with teammate Ben Bishop where they help other startups and businesses continue to innovate and grow. Dave is a regular conference speaker focusing on the intersection of technology and human behavior.

Abstract: Xamarin is delivering on the hopes and promises of a cross platform mobile solution. Apps look and feel native on iOS and Android for the simple reason that they are. With a history going as far back as the origin of the Mono Project in 2001, Xamarin is not a new sensation. A time tested set of tools, open source frameworks, and runtimes, Xamarin continues to push boundaries of innovation. Their motto is to delight developers, helping them do more and sacrifice less. How does this work?
In this session we will dive into how Xamarin delivers app experiences that maximize developer talent and resources while limiting sacrifices to designers, users, and the businesses dependent upon them.
Maximize code sharing: 60% and even 90% or greater, and why that’s important
What is Xamarin.Forms and when should you use it
Wearables and other extensions
HockeyApp, TestCloud and more
A year in the life using Xamarin — what it's like to work through release cycles from Xamarin as well as Apple and Google
Since 2012, Rendr’s team has been delivering high quality mobile applications using Xamarin for clients from startup to Fortune 100.

  8. the compromises

  9. • APIs - less than 100% • UI - doesn’t

    feel or behave native • Performance - slower than native by unacceptable margin • Tools - lacking in guidance and assistance • Community - resources, tools, plugins, etc. • Workflow - testing, deployment, monitoring, reporting

  12. the approach

  13. Silo approach iOS Windows Android Objective-C/Swift Xcode C# Visual Studio

    Java Android Studio No shared code • Many languages and development environments • Multiple teams
  14. Write once, run anywhere Lua Javascript Actionscript HTML+CSS Limited native

    API access • Slow performance • Poor user experience App generator
  15. iOS C# UI Windows C# UI Android C# UI Shared

    C# logic Xamarin’s unique approach Shared C# codebase • 100% native API access • High performance
  16. 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. ARM BINARY Runs natively .APP AOT .NET C# Bindings .APK Compile and Link .NET C# Bindings IL + JIT Runs natively
  17.  Always up-to-date Same-day support: • iOS 5 • iOS
