Topic - Codable Routing with Kitura Speaker - Pushkar Kulkarni Twitter - https://twitter.com/pushkar_nk Bio - Pushkar Kulkarni is a server-side Swift developer working with IBM. Prior to Swift, he worked on IBM's Java runtime, working on the JIT compiler and the Java standard library. Over the last two years, he has been contributing to open source Swift Foundation, focussed on making URLSession fully functional on Linux. He thinks Swift is the coolest language ever and is excited about the opportunities it offers on the server side. Abstract - Swift 4 introduced the Codable interface that, through JSONEncoder and JSONDecoder, makes working with JSON a really pleasurable experience. Encoding and decoding JSON often becomes the most complex part of working with RESTful APIs. Using Codable, Kitura 2.0 offers to take up the responsibility of JSON processing, allowing you to work directly with your own Codable types, in a type-safe manner. Using KituraKit, you may also share type definitions between the iOS app and the server side.

Topic - Exploring Clang Modules Speaker - Samuel Giddins Twitter - https://twitter.com/segiddins Bio - Samuel is a developer well-versed in the rituals of writing developer tools that occasionally work. By day, Samuel works on making the mobile developer experience at Square less arduous; by night he can be found breaking Bundler and CocoaPods. Before this whole 'developer' thing, Samuel studied in the highly impractical Mathematics & Economics departments at University of Chicago, learning subjects such as 'numbers', 'social theory', and 'memes'. When not coding, Samuel is often in the kitchen, marveling at the fact that dinner smells better than it looks. Abstract - Swift and Objective-C frameworks share the same underlying module system, based upon Clang Modules. They are intended to replace header files as a way of communicating the interface for a library, but they come with their own set of edge cases. We will examine how Clang modules are able to replace `#import` statements, some of the consequences of using modules, and how the design of Clang modules has influenced Swift's library story.

Topic - Finally Solving the Expression Problem Speaker - Brandon Kase Twitter - https://twitter.com/bkase_ Bio - Brandon Kase brings typed functional programming to weird places. He has shipped production code on Android with Kotlin, iOS with Swift and React Native, and Web with JS/Flow/React. Brandon is currently building a new cryptocurrency at O(1) Labs. He came across functional programming while pursuing a B.S. in Computer Science from Carnegie Mellon University. Brandon is excited that strong static typing and functional programming are becoming mainstream, and believes that techniques once reserved for academia will help industry produce more reliable software. Abstract - UIKit let's us describe view hierarchies by putting together a bunch of UIView and UIView subclasses. We can even create our own views by subclassing UIView ourselves without even reaching into UIKit! But we can't reuse this view description on AppKit or for serialization. Imagine for a moment, we had EnumKit, it's like UIKit, but the views are provided as cases of an enum. Now we can reuse the view description, but we can no longer create our own views without reaching into EnumKit (or forking the library). The 'Final Tagless' approach gives us the best of both worlds taking advantage of Swift’s powerful Self type inside protocols. try! Swift Tokyo Twitter - https://twitter.com/tryswiftconf try!

Topic - Best Docker Container in Swift Speaker - Takeshi Ihara Twitter - https://twitter.com/nonchalant0303 Bio - Takeshi Ihara is an iOS engineer of English learning services at Recruit Marketing Partners. He uses server side Swift in his personal apps. When not coding, you can find him bouldering or playing games. Abstract - Several years have passed since Swift was released as open source and Linux became supported. The adoption of server side Swift has increased. Meanwhile, Swift is constantly being updated, and the cost of supporting different Swift versions on multiple machines is getting higher. By using Docker, this cost can be reduced by preparing a virtual environment container with a fixed Swift version, so we can develop without relying on version. Also, since Docker does not perform full virtualization, disk usage is small, and virtual environment initialization and startup are fast. In this talk, I'll explore the best Docker container for Swift. Presentation Link - https://speakerdeck.com/player/aa6b4a7b27944a5e933dfdbc2a141d34# 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 - Protocol Oriented WebAPI Abstraction Speaker - Yuya Hirayama Twitter - https://twitter.com/hiragram Bio - Yuya Hirayama is an iOS engineer at VASILY Inc. He likes the idea of protocol-oriented programming, and pursuing code that realizes type-safe operation with minimal local definition by protocol + protocol extension. Recently, he is pulled toward the strong appeal of server side Swift, focusing more on Swift itself rather than iOS development. Yuya Hirayama also develops a virtual currency service as a side project, including the iOS application and the back-end API using Swift. In addition, he actively speaks at 'iOS Discord' and organizes 'Discord Offline', the first offline event of the community. Abstract - Most applications interact with the server via the Web API. I'd like to show you how to define protocol-oriented API to appropriately design API communication as the foundation of the application and make it easier to repair or change libraries that will be needed in the future. I will also introduce you to the design of a type-safe API abstraction layer combined with RxSwift. I will also show you my AbstractionKit framework. try!

Topic - Optimizing Swift code for separation of concerns and simplicity Speaker - Javier Soto Twitter - https://twitter.com/javi Bio - Javier Soto. Spanish, iOS developer in the SF Bay Area for the past 5 years. Worked at Pebble and Twitter before, now at Twitch. Big fan of Swift. When not writing code, he's playing chess, solving Rubik's cubes or flying planes Abstract - Separating concerns in code is often seen as a premature optimization when code doesn’t need to be reused, but it has huge implications in our ability to comprehend what code does. Let’s explore examples of this in Swift in what I like to call 'separating what code does from how it does what it does'. try! Swift Tokyo Twitter - https://twitter.com/tryswiftconf try!

Topic - UIImageView vs Metal Speaker - Shuichi Tsutsumi Twitter - https://twitter.com/shu223 Bio - Shuichi has been a freelance iOS developer in Tokyo, and works for Fyusion Inc. in San Francisco since 2016. Co-authored “iOS x BLE Core Bluetooth Programming” (2015) and authored “iOS Programming - Advanced 100 Recipes” (2013). He is the creator of some popular OSS repositoriessuch as iOS Sampler series. Abstract - Metal is an API that provides access to the GPU. Apple announced it's 10x times faster than OpenGL. In this session, I'll explain the basics of Metal, then compare the performance of graphics rendering with UIImageView. Even if you don't use the API directly, your app is implicitly benefitting from Metal. This comparison to a familiar class will lead you to be conscious of the GPU layer that we usually miss.
