Swiftにおける現実的なモック
About the content 2017年3月のtry! Swift Tokyoの講演です。映像はRealmによって撮影・録音され、主催者の許可を得て公開しています。 モックを使うことでプロダクション環境のデータを壊すことなく素早くテストを書くことができます。OCMockを使わずに、あまり手間をかけずにモックを書くにはどうしたらいいでしょうか。try! Swiftで話されたこの講演で、Veronica RayはSwiftにおける実践的でメンテナンスしやすくシンプルなモックを書く方法を示します。 テストは書きたいけれど… (0:11) …プロダクション環境のデータを壊してしまったり、テストが遅かったりするのは困ります。こちらはとても簡単なNSURLsessionを使う例です。みなさんのコードにもあるかと思います。もし実際の通信と同じリクエストを使ってテストをしたとすると、テストはすごく遅

Data Binding in the Real World
About the content This talk was delivered live in March 2017 at DroidKaigi. The video was recorded, produced, and transcribed by Realm, and is published here with the permission of the conference organizers. Data binding is not yet widely used by Android developers, and those who do use it seem to limit themselves to just replacing findViewById. However, the possibilities of data binding are endle
Modern Android: Ditching Activities and Fragments
About the content This content has been published here with the express permission of the author. Activities get destroyed when you rotate the screen, and they have a complex lifecycle. Using fragments is error-prone, and their lifecycle is even worse. How would you like a screen that doesn’t get destroyed on rotation, and a navigation that’s as simple as calling goTo(screen)? That’s what modern A
Swift: UIView Animation Syntax Sugar
This post originally appeared on Medium. Because closures make ugly couples If you hadn’t already heard, closures are a great tool to utilise in your Swift code. They’re first-class citizens, they can become trailing closures if they’re at the end of an API and now they’re @noescape by default which is a massive win in the fight against reference cycles. But every once in a while we have to work w

Reactive Android UI Programming with RxBinding
There’s an old saying that rings true in software… “The only thing that is constant is change.” The same can easily be said of Android. For example, how many times have you found yourself implementing a click listener, a text change listener ,or some other mundane callback that has a different signature? Android Studio alleviates us from having to memorize the callbacks, listeners, and their signa

The Weak, Strong, and Unowned — Memory Management in Swift
Memory management scares most developers when it doesn’t work as expected. Apple’s Automatic Reference Counting (ARC) magically handles most memory management we used to do manually, but still often needs guidance to work well. Swift provides us with cool tools like capture lists, unowned, and weak references to do so. In this talk, Hector Matos discusses memory leaks and retain cycles — how these
