Purpose comes in all sizes, big and small. My small purpose is to get through delivering this talk without embarrassing myself. My big purpose is to help as many people as I can in small ways every day. Notice I said small ways. Why small ways? Because the biggest moments in life tend to happen on the way to your plans. Think about the most significant moments in your life. The pivotal points that changed everything. If you’ve ever fallen in love, there’s a good chance that you never planned for it to happen on the day it did. And later… if it didn’t work out, I bet you didn’t plan that either. This is not to discount plans or goals. I firmly believe in having a plan and setting a destination before you embark on your journey. Goals are necessary. Sort of like the bread on a sandwich. The goals hold it all together but the best parts are of the the middle.

Did you ever notice that there’s no “fun” in Object-Oriented or Protocol-Oriented programming but that functional programming starts with “fun”? In this fast-paced talk we don’t emphasize functional programming because it’s good for you - we look at games and puzzles that go back nearly one hundred years to the invention of combinators. Don’t worry, we’ll get to the useful application part at the end - but let’s begin by just playing.

After almost five years of working with ReactiveCocoa and RxSwift, I still felt like reactive (Rx) programming had limited use in my work. But with Swift and RxSwift maturing, I was looking for a way to try it more. This spring, a colleague and I decided to use it whole-heartedly on a project. We established some guidelines that led us to an extremely clean Model-View-ViewModel implementation with a declarative ViewController and stateless ViewModel. And when Apple announced Combine at WWDC this year, we were glad we did because this code will convert to SwiftUI/Combine more easily.
To start, I’ll cover the basic ideas of Rx (RxSwift and Combine). But this talk is less about Rx operators and more about how to use Rx to build a reactive architecture. I’ll show some code from two apps—Trello (RxSwift) and a new workout app I’m working on (Combine). If you have no Rx experience, in this session I hope to show you some motivating examples that might convince you to give it a try. If you’re using Rx, I want to show you some techniques for using it to make MVVM structures that are more testable and easier to maintain.
Code Golfing is a fun type of recreational programming where “players” strive to achieve the shortest possible source code that implements certain functionality. Using Swift to Code Golf is fun in itself, but there is a lot we can learn from this exercise. Join me in exploring practical takeaways from thinking about each line of Swift code we write!

Have you ever seen a code comment saying “this should never happen”? Have you ever wondered what would happen if it did? Swift has a diverse set of error-handling capabilities, from using
throw to send errors up the stack to using a
Result to handle errors in asynchronous methods. In this talk, we’ll look at the landscape of handling errors in Swift, create new ways of expressing and handling them, and show how even the most impossible code-level situations can have 100% test coverage.

NFC has been around for a while and we use it every day in things like Apple Pay but how does it work and what features are actually available for developers to use? Until recently NFC was pretty limited on iOS and devs used to struggle to find use cases they could implement in their apps. NFC itself has plenty of applications but we were not able to take full advantage of them because of these limitations but now that Apple has announced tag writing support, we have more possibilities! Some of your Android friends might tell you: “Well we have had that for a long time!” and yeah it’s true, but without Apple opening their APIs it was hard for companies to find a compelling case to build apps where only one platform was going to be supported.
In this talk, you will learn the basics of Near Field Communication such as tagging, different types of tags and their specifications. We will also take a peak to these new features and implement some of them in a quick example.
Join me to see why I think learning about the new Core NFC features are important and the long-lasting implications they will have around the world.

Testing is critical, but can be difficult. In this talk we will explore using Swift’s protocol oriented programming for User Interface testing to create light-weight interfaces that are composed of user behavior and application state. We will discuss the pro’s and con’s of writing tests this way. We will also discuss options for further development of the technique. This talk isn’t just for testers. This talk is also for product managers, designers, developers, and customers! As a use case, will will walk through logging into and using a movie rating app. We will build up a protocol that allows tests to be read as a set of instructions for an actual user. When we are done, we will have a better understanding of behavior driven development, UI testing, and protocol oriented programming in Swift.

Follow me on a journey of peril and intrigue as I walk you through the most difficult bug of my career. The many frameworks of Cocoa Touch are the cornerstone of modern iOS apps. But what happens when the building blocks start to work against you? I’ll take you through the lifecycle of a bug we encountered at Tinder on the eve of the launch of iOS 12. To this day, it is one of the most puzzling and challenging issues I’ve encountered. The solution to which has wide-ranging implications in any app that utilizes NSUserDefaults. At the end of this session, you will learn steps you can take to avoid a devastating pitfall in Foundation. This issue was discovered in Tinder and I will walk you through a possible solution should you encounter it in your own apps as well.
Attendees should expect to walk away with an understanding of the deeper workings of UserDefaults and unexpected, yet commonly experienced, issues with the defaults system.

They said Swift is “protocol oriented,” so you wrote protocols. But you wanted them to be generic, so you added associated types. But your collections broke, so you added type-erasers. But your “as”-casts broke, so you switched to Any. But then everything broke, so you read about Mirror. And the tears began. Why did it have to be so hard to make an array?
It doesn’t have to be so hard. But it’s very easy to use the wrong tools to solve the wrong problems. In this session I’ll help you reevaluate what it means to write generic Swift and how to choose the right tools for the job. Whether your goal is reusable view controllers, flexible networking, data-driven UI, effective unit testing, or just the joy of elegant data structures, you’ll learn how to work with Swift and not fight the compiler.
This talk assumes familiarity with Swift syntax for generics, protocols, extensions, enums, and first-class functions (such as completion handlers), as well as the basic differences between Swift structs and classes. More advanced topics, including protocols with associated types, enums with associated data, closures, and functions as return types, will be introduced and explained.

Tinder’s famous LikesYou feature has a golden pill view that shows the number of swipe rights a particular user receives while using the app. Inspired by Robinhood’s stock ticker, Tinder has recently upgraded their pill view to have similar sweet scrolling animation. However, since the pill view had letters along with digits, it faced different set of problems. The session will explain how this unique ticker view has been implemented.Through this talk, you will be able to understand what it takes to implement a tickerView like the one from Robinhood and how Tinder has solved the unique set of challenges due to implementing scrolling digits and letters in a single view.

Extensions allow you to add functionality to a previously existing class, structure, enumeration, or protocol. This gives you the power to add new behavior to your own code, third-party libraries, and even Apple frameworks. While this sounds simple, extensions allow you to up your Swift game and amplify your code in so many ways! In this talk, we will explore using extensions to have cleaner code, conform to protocols, add new initializers, extend protocols, and so much more. We’ll also show off some extensions that you didn’t even know that you wanted. Fall in love with extensions today!

App development is inherently hard at scale. On one side, app developers have to create new features that users can use, which in turn helps the business make money. On the other side, app developers need to keep apps fast, consistent, fluid, fun, modular and everything users expect any app to be. A small app team can do both at once, but as the team scales, keeping focus on these two things equally in a connected way is actually hard, especially at Wayfair with over a hundred app developers and multiple apps across iOS and Android and business areas. Come listen to our journey so you can learn from how we organized app teams to scale to new heights in order to deliver successful “appy” apps!

ARKit itself seems to have very limited functionalities. However, I extended what ARKit can do with CoreML when I developed my first AR app, Notable Me(https://itunes.apple.com/kr/app/notable-me/id1453810473). It got featured on ProductHunt(https://www.producthunt.com/posts/notable-me). I will share how I developed this AR app, so other iOS developers can also come up with creative ideas to use ARKit and CoreML. Also, I will share how a mobile developer, who doesn’t know how to use Tensorflow, can create custom ML models using Turi Create, Apple’s open source library to easily create mlmodels.

When you turn on your phone’s screen, there’s only one thing that’s always there every time, reassuring you that everything is in order: the time. But how does your phone know what time it is?
Through the ages, the question of “what time is it” has gone from inconceivable to mildly interesting to extremely difficult to trivial. Let’s look at how it got here and how it works today. We’ll cover how anyone knows what time it is, how computers think about time, and how your phone stays up to date(/time).
You’ll learn about an important but oft-overlooked technology, timekeeping. Plus you won’t look at your lock screen the same way again.
We developers love building fully featured apps and we build them the best way we know; but sometimes this leads us to toil for too long on apps that could have succeeded just as well, with insanely less effort and time.
For the next 25 minutes we ask: do apps need server backends to deliver content? How can apps succeed while missing important features? In this non-coding, product and customer oriented session, learn about the decision-making philosophy for the WeCroak app; an app that cut development corners, while still delivering a compelling user experience. The App uses an on-device content architecture that eschews a backend and lacked seemingly important features at launch. After the App went viral, how did this architecture and lack of features hold up?

As a code base grows, and its test suite covers even more test cases, an important question arises: how do we know our tests are covering every case? Even when practicing test-driven development, some program branches inevitably become omitted from our test suites, a once-effective testing strategy now fails to capture every case, and team churn causes a loss of context on why certain tests were written the way they were.
Finding ourselves in this position is stressful at best, and can cause us to question the value of automated testing altogether. This is where the practice of mutation testing becomes essential. This session will go through an explanation of what mutation testing is, how to use it, how not to use it, and what tooling exists to help us practice automated mutation testing. In addition, the metrics involved with mutation testing will be examined, giving you a sense of how to wield them. By the end of this session, you’ll walk away with additional tools, practices, and metrics to help you and your team engineer test suites which more effectively detect bugs and missing functionality. ✅
