Summer refactor, anyone?

When the Instagram team rewrote their iOS feed from the ground up, they learned more than they anticipated about collection views, diffing, and the dangers of too much spaghetti code. Ryan Nystrom shares his story of what it takes to ship a successful refactor!

Swift and the Legacy of Functional Programming

Rob Napier has been to Monad, the Functor of Doom, and also to the top of Hacker News. He has seen the map, flattened and lensed. He has folded the infinite, lifted a Maybe, and he would do it all over again. But from what he has seen, from Haskell to Church, we can rely on one truth:

Swift is not a functional programming language.

Pushing too hard to make it one fights Swift and breaks Cocoa, but Swift has absorbed some fantastic lessons from the functional world. This summer, learn how to use functional features best while staying true to Swift, playing nice with Cocoa, and embracing Protocol Oriented Programming.

Reactive Programming with RxSwift

Functional not your jam? You may have heard about reactive programming, and maybe even checked out RxSwift, but if you’re not using it in your daily development, you’re really missing out! Scott Gardner introduces you to the world of reactive programming and shows an easy way to start off learning Reactive Swift. Come see how reactive programming with RxSwift will change your life and make you richer than your wildest dreams, because the best-laid summer plans always start with “How can I get rich quick?” 🤔💰

MVVM with RxSwift

Wanna get next-level fancy with reactive programming this summer? MVVM is the critical design pattern for front-end engineers. Max Alexander shows you how to streamline your development process by replacing your MVC pattern with MVVM, all while incorporating RxSwift. He’ll go over the MVVM basics, creating custom observers, wrangling disparate APIs, and manipulating calls using concurrency and dispatch queues. Your code will be so neat that you could quit your job and leave it for the next guy in impeccable condition.

So What’s Really the Best Architecture??

But okay, let’s not dismiss MVC without a fair fight. Luckily Krzysztof Zabłocki gave the perfect talk to help us choose the best architecture for our projects. MVVM, MVC, VIPER… so many acronyms, but which architecture is the best? Let’s talk about the things that matter for good app architecture for iOS.

Sommer’s Swifty UI Summer

Sommer Panage explores how the structure and properties of the Swift Language make writing UI code simpler. We will take a look at common pitfalls while building the UI layer and examine a Swifty way to improve upon it. The talk will examine modeling view state with enums, useful third-party Swift libraries, unifying views via protocols, and more!

Become a Machine Learning Expert Before it’s Old News

The news says machine learning is the Next Big Thing™️. That means by fall it will be So Last Summer™️. Don’t be that one person who can’t talk shop about ML… get up to speed with Alexis Gallagher’s fast, concrete, down-to-earth survey of machine learning from the perspective of iOS & Swift. He outlines how TensorFlow is like AVFoundation, how model training is like UI design, and how you can use iOS to gather big (enough) data and to exercise modern models using fast native code.

Alexis is as an independent consultant, building all sorts of systems with Swift, Clojure, bash, a heartfelt sincerity, a nagging skepticism, and the motley wisdom from his past adventures in science, finance, and comedy.

Chris Lattner

Chris felt like there could be something which would retain the benefits of the C, Objective-C, and C++ family, but help move the industry forward. Compiler, languages, and tools enthusiast who has been dabbling in Swift for some time now.

Kevin Ballard

Kevin works at Postmates, contributes to (and releases his own) open source libraries, participates in swift-evolution, and submits patches to the Swift project. He’s been writing Cocoa for over a decade, doing iOS development since iOS 2, and using Swift since the day it was announced. His current project is a baby girl and he can’t wait until she’s old enough to begin learning Swift.
