Topic - All about linking libraries Speaker - Kishikawa Katsumi Twitter - https://twitter.com/k_katsumi Bio - iOS Developer. Love to create small tools for developers. Abstract - 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. a 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.

Topic - Discover memory leak with Testcase Speaker - Nobuo Saito Twitter - https://twitter.com/tarunon Bio - Nobuo, a.k.a tarunon is working at Mercari. He likes to cook, play games and program. He doubled the time he plays games because he updated Splatoon before the release of the Smash Brothers SP. Abstract - In Swift, memory are managed with ARC, so it's occured 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.

Topic - Graphics like Pixar using Swift Speaker - Michael Petrie Twitter - https://twitter.com/kapsy1312 Bio - My name is Michael Petrie, but everyone calls me Kapsy. I work for ZOZO Technologies and lead the iOS measurement framework team. I have a background in games and real time programming, using C and C++, and yearn for the day when we can all decide on a common ISA (Instruction Set Architecture) and be happy. Abstract - 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.

Topic - Native macOS application, or the world of AppKit Speaker - 1024jp Twitter - https://twitter.com/1024jp Bio - 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. Abstract - 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 familier with Human Interface Guidelines and understand target OS well. By the way, we feel that 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.

Topic - Introduction to Swift Keypaths Speaker - Benedikt Terhechte Twitter - https://twitter.com/terhechte Bio - Benedikt works as a Senior iOS Developer at the professional network XING. In previous jobs he developed solutions for customers such as Disney or Daimler-Chrysler. As an Indie Mac developer, he launched successful apps such as PhotoDesk and Hirundo. Benedikt started investigating Swift right after the 2014 release and writes about it on his popular blog. He also initiated the Core Value and SourceKittenDaemon open source projects Abstract - 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.

try! Swift Tokyo Conference 2019 - try! Swift is an immersive community gathering about Apple Technologies, Swift Language Best Practices, Application Development in Swift, Server-Side Swift, Open Source Swift, and the Swift Community in Tokyo! Topic - Generics in protocol extension Speaker - Hikaru Yoshimura Twitter - https://twitter.com/_yuu_ Bio - 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. Abstract - The protocol only handle existensial type like associateType. For some protocol, when we give some functions in protocol extension, we must put a concreate type. Protocol extension will work like searching function based on type, so it's needed concreate 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 existensial type like associatedType by using Curry-Howard correspondence.
