    A Tale of Two Tracers / Jonathan Blocksom

    We will walk through the design and coding, in Swift and then in Metal, of a ray tracer — a program to make images by computing how light bounces around a scene and into the eye. How will the expressive, functional, protocol-oriented Swift ray tracer compare with the one written for screaming performance in C++ oriented Metal?

    Advanced Beginner Git / Laura Savino

    You can commit, pull, and push from the command line when you need to, and you're ready to learn some more git features–but you aren't trying yet, because your source code is a *terrifying* place to experiment with unknown git commands. In this workshop, we'll work together in a pre-existing toy repo so you can get comfortable doing things like: browsing history to find the source of a bug (bisect & blame), using the most helpful of Xcode's built-in source control support (no, it's not snapshots), and getting back to the state where "everything worked" (reset, stash, reflog).

    Art of the Sell / Jaimee Newberry

    Throughout her career Jaimee has held a range of roles from in-house team designer/manager/director, a partner in several agencies, an independent consultant and executive level management. Though her various job descriptions never included mention of the word “sales” she realized that across all these roles she not only had to sell her own work and ideas, but the work and ideas of her teams and colleagues, as well. It stands true that the most important skill she ever learned was how to sell.

    Through stories of client interactions, fumbling and learning experiences, Jaimee will share with you her two rules of design and her “Check-Yourself Checkpoints” which have served to improve her client/team/human interactions with results that close the deal. If you interact with human beings, you won’t want to miss this talk.

    Building buddybuild / Chris Stott

    While building an iOS app a couple of years ago, Chris and several of his colleagues became frustrated with their workflow and the difficulty to set up and maintain iOS continuous integration & deployment systems.

    They started buddybuild to solve these problems for all iOS developers.

    Today, thousands of companies are using buddybuild for continuous integration and deployment. Chris will share the story of building the company and architecting the systems required for supporting running xcode in the cloud.

    Debugging and Testing / Walter Tyree

    This talk begins by looking at some of the new debugging and reverse engineering tools that have recently appeared. Then we dive into documentation options and admonish you to leave a visible trail for the developer that inherits your code. Next, we will highlight strategies for adding testing to legacy code as well as how we have added testing to existing projects. Sprinkled throughout we will look at the most interesting and wierd bugs we've found during our recent explorations and offer advice on our thought process for figuring out their causes.

    Financing Your Technical Debt / James Dempsey

    We use the term ‘technical debt’ to describe parts of our codebase where the code, for a variety of reasons, is not to our satisfaction. In this session we will talk about different ways of thinking about technical debt, including exploring the debt metaphor and the tradeoffs of technical debt in the development process. The remainder of the session will be a discussion with attendees sharing thoughts and experiences of technical debt.

    Firebase: Totally Not Parse All Over Again (Unless It Is) / Chris Adamson

    With Facebook shutting down Parse, everybody knows to never again depend on a third party for their backend solution, right? Sure, and after you spend six months trying to write your own syncing service, how's that working? In 2016, Google has added a ton of features to Firebase, their popular backend-as-a-service solution. Firebase's primary offering is a realtime database in the cloud that syncs changes to and from multiple concurrent users, and their Swift-friendly iOS SDK makes it ideal for mobile use. In this session, you'll learn how to set up a Firebase backend and build an iOS app around it.

    Increasing Productivity in Xcode / Mark Gerl

    Xcode is a powerful tool. It can be overwhelming, and frustrating at times. Come to a talk about how you can update your projects to make your productivity faster.

    Some example content:

    • How to set up your project with .xcconfig files to make updating your build version number and all of your extensions to use the same version number - a requirement for iOS, iOS extensions, and Apple Watch apps and extensions. Instead of updating each target by hand, you can automate this for your entire project.
    • How to setup your code to use the Swift Objective C header, without lots of #ifdefs to determine what project you are compiling. (Each target has it’s own Swift Objective C header, so you can’t share them easily.)
    • Using a build script section to update resources based on your build.
    • Other lessons learned from our plethora iOS, tvOS, and watchOS projects at AOL.

    Intro to iOS 3D Graphics Programming / Jonathan Blocksom

    This hands-on course will introduce attendees to the fundamentals of 3D Graphics on iOS using SceneKit and a bit of Metal. No previous graphics programming experience is necessary but students should be familiar with Swift programming.

    The morning will focus on introducing SceneKit and how to create 3D scenes and camera motion with code and external 3D resource files.

    In the afternoon we will learn about Metal and OpenGL, and how shader programs can be used for custom rendering. We will end the day exploring the cool effects you can do with SceneKit, and attendees will have the chance to try a number of simple projects demonstrating them.

    There will be a math refresher during lunch, covering the basics of vectors and matrix multiplication with an eye towards understanding lighting calculations and transformation matrices.

    Keeping Secrets for iOS Developers / Randy Beiter

    High profile lapses in security are becoming more and more common these days yet iOS applications can still frequently miss the mark on securing data whether the user's or the application's itself. Are you using SSL for talking to a remote API but embedding the credentials for the service cleartext in your application bundle? Do you have high confidence the server you're communicating with is actually your own? Charging for premium content already delivered with your app and expecting the AppStore's default protections to secure it? Is your app ready for Apple's coming changes to App Transport Security that will be implemented at the end of 2016? Learn some tips and gotchas to keeping secrets on the device and in your application bundle with the iOS SDK at this session geared for the iOS developer but potentially useful to any mobile developer.

    Reverse Q&A Panel / Chris Adamson

    "In Soviet Russia, panel questions you!"

    Borrowing an idea from the Penny Arcade Expo (PAX) and the panels held there by Harmonix (makers of the "Rock Band" games), a "Reverse Q&A" literally turns the tables on the traditional panel. Speakers become questioners, and attendees are the ones with the answers.

    It's a new and novel idea, letting attendees have their moment in the limelight to say what they're really thinking, and letting speakers learn more about what people want from conferences, books, and their development life in general. With a combination of polls, follow-ups, person-on-the-street questions, and funny stories that we can all relate to, the Reverse Q&A will shake the cobwebs out of the old panel format and turn it into a two-way discussion that both sides of the mics can learn from.

    Scouting Swift 3 / Greg Heo

    Swift 3 brought a massive set of changes to the language. In this talk, we'll go over some of the highlights: what you need to know, why they've made the changes they have, and what's coming up in the future. Whether you're 100% on Swift or have mixed Objective-C + Swift projects or are just starting the transition, there will be something for you: Swift features, cross-language bridging, and even some live coding.

    Speaking To Your Phone: Beyond Siri / Josh Smith

    In this advanced talk, you will learn how to build voice and speech systems using both 3rd party and Apple frameworks. Voice and Dialog interfaces are very different from the UIs developers are commonly to. This talk will also cover an overview of how to build dialog system and where the state-of-the-art is still (sometimes) lacking.

    The Language of Mobile Software is APIs / Tim Burks

    We’re all excited about using the same language to write our mobile apps and cloud services, but as we do, we’ll still need to work with a few things that aren’t written with Swift. Fortunately, there are some great patterns that we can use for doing that. In this session we’ll talk about two technologies that you can use to make your app speak with APIs written in any language: OpenAPI and Protocol Buffers, and then we’ll see how to use them from clients and servers that are written in Swift.

    Using Torch7 and Neural Networks on iOS / Josh Smith

    Torch7 provides a Matlab-like environment for state-of-the-art machine learning algorithms. It is easy to use and provides a very efficient implementation, thanks to an easy and fast scripting language (Lua) and a underlying C implementation.

    In this moderately advanced tutorial I’ll be covering how to use Torch7 on iOS to construct simple neural networks and do some cool stuff.

    Write That Down / T.J. Usiyan

    Debugging is quite the challenge. Tests and design patterns often fail us and we are left printing out values in lldb or pulling in logging frameworks from third parties. Apple has finally released a tool of their own to address logging and we are going to get set up using it in this session.
