iOS 8 is the biggest release since… iOS

iOS is now available and it is huge.  Huge.  Bigger than that.

There are 15 new frameworks and over 4,000 new or modified APIs.  The primary goals of this release are extensibility and adaptive ios8 logo(reactive) design, and they have gone very far with both, especially extensibility.

Among the highlights for developers are APIs for

  • Fingerprint authentication
  • Home Automation
  • Health and Medical
  • Photo editing
  • Interacting with cloud-based documents
  • Identifying more bar codes
  • Audio/video for gaming
  • Apple Pay and general NFC

A Xamarin Project

Recently, Steve Smith, CTO of Falafel suggested we form a small team to re-write splash screenour Falafel2Go application which had been written a year earlier in Xamarin.  The goal was to learn, to demonstrate and to blog about Xamarin Forms.  This project was undertaken by Jesse Liberty, Venkata Koppaka,  and Josh Morales, with J. Tower kibitzing and Steve Smith providing the carrot and the stick.  All of us were working in our down-time, and so we didn’t expect the project to move along terribly quickly.

We started by creating a brand new Xamarin Forms application and setting up the code structure.  Xamarin Forms practically cry out for MVVM and so we began by creating  Views, Models and ViewModels folders.  We spent quite a bit of time discussing navigation and decided that we would not fight the platform, but that V1 would use a relatively simple ListView to act as a menu of Activities that the user could choose from.  Later in the process our designer, Matt Kurvin provided us with some beautiful visualizations for navigation.

Hybrid Apps in Xamarin?? Part 2

In a previous blog post I started to create a hybrid application in Xamarin (see that post for why this is not an entirely crazy idea).

StockPhotoAppI glossed over the implementation of IDataAccess. Let’s focus on that now.  In the iosStockPhoto project we have divided the implementation of IDataAccess into two partial class files, DataAccess.cs and DataAccess.ios.cs.  The latter handles the path for the database file,

Hybrid Apps in Xamarin??

Today I begin a new series of blog posts on creating Hybrid Applications in Xamarin.

This material will excerpted from the presentation I’ll be making at Evolve 2014, though I confess I’ll be holding back some cool stuff for the actual presentation.

Hybrid Xamarin??

A few questions come to mind:

  • What, are you nuts?
  • Why Hybrid?
  • Why Hybrid With Xamarin?

These all revolve around the central point that the beauty of Xamarin is that you write native applications for iOS, Android and WindowsPhone in C#. The key phrase is native applications. Hybrid is not native.

But Hybrid has a number of advantages, not least of which is that it can be a tremendously helpful bridge from your current skills and interests to creating native applications down the road.

As Joseph Hill (co-founder of Xamarin) writes in one of his slides that I ripped off for the Evolve presentation, “It’s Not A Battle To The Death, It’s About Using the Right Tool For the Job.”

I’m teaching a 2-day 16-hour hands-on course on Xamarin

I’m very proud to announce that I’ll be teaching a 2 day hands-on course on Xamarin iStock_Joyous-computer-man-on-beach-XSmall at Falafel in Hudson Ohio.   This will be a very intensive course, but no prior Xamarin experience is needed, though you do want to be comfortable with C#.

During this course you will learn how to set up your Xamarin development environment, and how to create meaningful and useful Xamarin applications using best practices from the very start. Topics covered include MVVM, Events, Data-Binding, creating forms, working with Images, Fonts, Files and Maps, accessing the web, working with data locally and in the cloud, using the capabilities of the phone, migrating from web or hybrid applications, native iOS and Android development, working with lists, navigation, backgrounding, memory management and publishing your application.​

Classes will run on September 17 – 18, from 9:00am to 5:00pm Eastern Time

Hold It Right There: Xamarin and Unit Testing

We’ve come a long way in this series on Learning Xamarin, but we haven’t Not Negotiable even begun to discuss Unit Tests, let alone Test Driven Development.

There are lots of articlesbooksPluralsight courses, and other sources on why Unit Testing is not only a good thing, but an essential part of building any modern application.  But it is incredibly easy to overlook, especially when showing demo programs.  Let’s rectify that.

In my previous article, I added MVVM Light to the new BookLender project.  Before we go any further, let’s add nUnit.  Continued here.

I’ve Become A Big Fan of Amazon’s WhisperSync

I’ve discovered Amazon’s WhisperSync, and I’m in love.
The idea is that you buy an Audible book and a Kindle book — and your device (which can be a computer, iPad, Kindle, etc.) keeps them synchronized.  This allows two wonderful scenarios.

First,  and I’m doing this with Capital in the 21st Century, and it is great, you can read the book and when something comes up that prevents you from reading (driving, doing the dishes, etc.) you just click on the headphones, and it picks up reading to you right from where you left off (ok, from the top of the current page).  When you are done being distracted, push a button and you are back to reading on your own.  Just wonderful.

Second, and the need for this is rare, but reading Ulysses is a perfect example, you can have it read to you while you read along.  It will even turn the pages for you.  This has enormously enhanced both my understanding and my enjoyment of Ulysses.

Thou lost one. All songs on that theme. Yet more Bloom stretched his string. Cruel it seems. Let people get fond of each other: lure them on. Then tear asunder. Death. Explos. Knock on the head. Outtohelloutofthat. Human life. Dignam. Ugh, that rat’s tail wriggling! Five bob I gave. Corpus paradisum. Corncrake croaker: belly like a poisoned pup. Gone. They sing. Forgotten. I too; And one day she with. Leave her: get tired . Suffer then. Snivel. Big spanishy eyes goggling at nothing. Her wavyavyeavyheavyeavyevyevyhair un comb:’ d.

Joyce, James (2014-07-21). Ulysses (Illustrated) (Kindle Locations 5159-5163). . Kindle Edition.

That is a heck of a lot easier to work your way through when it is read to you by a professional reader and you are looking at the page at the same time.
