Swift is the language which we cannot build native application in the iOS or macOS world without, but what is the native application? Is it the native application using Cocoa framework with Swift? To be proved native merits, programmers should know frameworks well, be familiar with Human Interface Guidelines and understand target OS well. By the way, we feel that the Marzipan is just around corner. In this talk, I'd like to talk about the essential point of view in building beautiful macOS native applications.

1024jp

1024jp is hobby macOS developer/designer. Besides working as a professional academic researcher in real life, 1024jp invests entire leisure time in developing macOS applications by doing every process from coding to drawing icons. The most active project is CotEditor, a native macOS plain-text editor. CotEditor is currently one of the largest open-sourced macOS application written in Swift but has been developed by 1024jp alone since CotEditor was officially taken over from the ex-developer five years ago. Besides, 1024jp organizes also “macOS native,” a community for sharing knowledge about native macOS app development in Japan.

In this talk, I'll talk about Swift Literals to your deeply understanding. By following the 'Literal Object' journey from Swift Code to SIL, and LLVM IR code, you can see how literals are handed over to the app as exact data from code string, with Intrinsic Protocols. Also, I'll focus on Literal exploitation using Intrinsic Protocols and new features for literals in Swift 5.0. By my talk, you will be a developer well known about Swift Literal.

@noppefoxwolf

The protocol only handle existential type like associatedtype. For some protocol, when we give some functions in protocol extension, we must put a concrete type. Protocol extension will work like searching function based on type, so it's needed concrete type in somewhere. For example, for some type called A, sometimes we want to write extension using List[A] finaly. In this talk, I'd like to consider how to create generics by force from existential type like associatedtype by using Curry-Howard correspondence.

Hikaru Yoshimura

Hikaru Yoshimura works as a Scala engineer. He used to study type systems when he was in the university so he can program using some functional languages a little bit. He sometimes brings the good parts of languages like Scala, Haskell or OCaml to Swift.

@_yyu_

Keypaths were added in Swift 4. They're a fantastic feature but sometimes it feels difficult to find good situations for using them. However, when understood and used the right way, keypaths allow you to implement additional abstractions into your codebase that would be much harder with generics or protocols. In order to be able to do that, though, it is useful to intuitively understand when to apply the Keypath pattern.
This talk will first explain the different types of keypaths that exist and then go through real world examples to showcase how they can be leveraged in your own projects.

@terhechte

In Swift, memory are managed with ARC, so it's occurred memory-leak easily with bad code. How do you avoid memory-leak? Coding rules, Code review or QA as last bastion? Of course we are lazy, so we like something automated than effort or guts. As 4th way, I'd like to talk about test case implementation with Mirror.

This is a talk about some of the hurdles faced when writing a simple Ray Tracer from scratch, using Swift.
Ray Tracing is the cornerstone of Pixar's infamous Renderman 3D rendering technology, which dominates the animated film industry. It works by physically modeling light rays and their interactions with objects and surfaces.
Within recent years there has been a renewed interest in real time Ray Tracing, with the advent of more powerful and specialized hardware such as NVIDIAs RTX. Even renowned programmer John Carmack has stated that 'all roads lead to Rome', when asked about the future of real time computer graphics and Ray Tracing.
While I enjoy working with traditional graphics rasterizers, I have always been interested in physically modeling light, and have wanted to learn more about the processes involved. Here I talk about how I programmed a Ray Tracer that renders a simple scene from first principles. Given the timing, it also seemed like the perfect opportunity to test the versatility of Swift.

@nictheawesome

Why do we really write code? I’ve been wondering: how long is code suppose to live, and just how disposable is it? If our end goal is to deliver great and useful features for our users, is it worth writing disposable code to get to robust code? As good programmers we hone our craft, but let’s look at how can we put all that knowledge to good use so we build the right things, rather than just building things right.

When developing an iOS application, you rarely do not use libraries or framework. We use OS provided frameworks such like UIKit and Swift standard libraries. We also use useful third-party libraries.
At the same time, everyone may have suffered from link errors, duplicate symbols, weird error messages from package managers. It is difficult to solve link errors because the cause of the problem comes from various things such as project setting, the library is static or dynamic, distribution method of the library or execution environment (on device or simulator).
Learning the mechanism of the link makes you possible to solve the problems.
In this talk, I will explain about a library and framework which can be used for iOS applications and explain the mechanism of how external libraries will be linked with your applications.

We’ve all had the experience of debugging an app only to end up looking at a wall of assembly that seems impossible to understand. Or maybe you’ve wanted to look at the source code for a UIKit method to understand why it behaves the way it does. In this talk, I’ll show you that even us regular developers can learn enough assembly to help track down bugs, to reverse engineer parts of the system frameworks, and to understand our own code more deeply.

Over the year, Core Data has gained a pretty bad reputation amongst developers who prefer to use another service like Realm for their local persistence. In this talk I will make an argument for using Core Data and why it's not so bad. I will share some examples of where it's easy to go wrong with Core Data, and how to avoid those pitfalls. I will also quickly go over setting up Core Data in an app and by the end the audience should have a couple of simple rules that should help them safely integrate Core Data in their apps.

It’s never been a better time to start learning how to code. Technologies are evolving and growing every day, and with Apple’s recent advances in Swift and Swift playgrounds, Apple development has never been easier to try. However in the tech industry, there still exists a large gap between individuals trying to enter the industry as a Software Engineer, and the hiring demands of tech companies trying to fill their engineering roles. This talk will focus on this gap - the leaky bucket we see in the demographics of Software Engineers. We’ll talk about how we as Software Engineers can strengthen the existing Apple developer community by discussing how we can extend a hand to those trying to enter. This will involve topics such as sharing perspectives from non-Software Engineers about the difficulties of breaking the barrier, as well as the unique opportunity that Swift and this Apple developer community can provide.
