Calling Haskell from Swift
struct User { let name: String let age: Int } // birthday(user: User(name: "Anton", age: 33)) = User(name: "Anton", age: 34) func birthday(user: User) -> User { // Calls Haskell function... } To support this workflow, we need a way to convert the User datatype from Haskell to Swift, and vice versa. We are going to serialize (most) inputs and outputs of a function. Even though the serialization as

Creating a macOS app with Haskell and Swift
First part of an in-depth guide into developing a native macOS application using Haskell with Swift and SwiftUI. This part covers the set-up required to call Haskell functions from Swift in an XCode project using SwiftUI. #haskell#swift#macos This is the first part of an in-depth guide into developing a native applications for Apple platforms (macOS, iOS, etc.) using Haskell with Swift and SwiftUI
Integrating Zig and SwiftUI
Building a native GUI for a cross-platform application is a decades old problem. Nowadays, most people just don't and fallback to using a non-native experience such as Electron instead. One approach to building a native GUI for a cross-platform application is to write all of the business logic in a cross-platform language (C, Rust, Zig, etc.) and then write the platform-specific GUI code. This is
How Swift Achieved Dynamic Linking Where Rust Couldn't - Faultlore
How Swift Achieved Dynamic Linking Where Rust Couldn't For those who don’t follow Swift’s development, ABI stability has been one of its most ambitious projects and possibly it’s defining feature, and it finally shipped in Swift 5. The result is something I find endlessly fascinating, because I think Swift has pushed the notion of ABI stability farther than any language without much compromise. So
Swift Concurrency チートシート
Swift 5.5 で Swift に Concurrency （並行処理）関連の言語機能が追加されました。これによって、 Swift で非同期処理・並行処理のコードをより簡潔かつ安全に書くことができるようになります。 しかし、 Swift Concurrency は Structured Concurrency や Actor など、多くの人にとって馴染みが薄いだろうと思われる概念を含みます。具体例を通して効率よく Swift Concurrency を習得できるように、本記事では iOS アプリを題材に、 Swift Concurrency 導入以前（ Before ）と導入後（ After ）のコードを比較することで、何がどのように変わるのかを紹介します。 なお、 Swift Concurrency 関連の機能は次の三つに大別できるため、本記事の Before & After の例も
Let’s Build a Regex Engine
How to understand the language of <\/?[\w\s]*>|<.+[\W]> Ever wondered how regex works under the hood? How does it understand an incantation like "<\/?[\w\s]*>|<.+[\W]>" and magically produces a desired result? This series is going to describe exactly how it works and how to implement a feature-rich regex engine. Now you might be wondering, why would you want to do that? Well, turns out, this is a
GitHub - nicklockwood/RetroRampage: Tutorial series demonstrating how to build a retro first-person shooter from scratch in Swift
Ever since I first played Wolfenstein 3D on a friend's battered old 386 back in 1993, I was hooked on the First-Person Shooter. As an aspiring programmer, I wanted to recreate what I had seen. But armed only with 7th grade math and a rudimentary knowledge of BASIC, recreating the state-of-the-art in modern PC 3D graphics was hopelessly beyond my reach. More than two decades later, a few things hav
1日でSwiftコンパイラを作る！Swiftコンパイラインターンを開催しました - クックパッド開発者ブログ
こんにちは、モバイル基盤部の @giginet です。 去る3月28日、Cookpad Spring 1day Internship 2019の一環として、Swiftコンパイラコースを開講しました。 最近のSwiftコンパイラ 近年、iOSエンジニアの間ではOpen Source Swiftがホットトピックとなっています。 ここ1年ほど、わいわいswiftcというSwift言語処理系に関する勉強会が盛り上がっていますし、 先日のtry!Swiftでは、参加者がSwift自体にcontributionするOpen Source Swiftワークショップが開かれました。 Swiftコンパイラに用いられているLLVMという技術は今、多くの言語処理系で利用されています。これを学ぶことで、さまざまな言語処理系に応用することができます。 このインターンは、Swiftコンパイラを例に、LLVMに触れ、コ
Swiftのエラーハンドリングはなぜ最先端なのか - Qiita
Swiftのエラーハンドリングは他のメジャーなプログラミング言語のどれとも異なる新しい仕様を持っています。特に、検査例外を持っているのですが、これはJavaで採用された以降はほとんどの言語で採用されていないため、現代では否定されている過去の間違いだったと広く認識されていると思います。そのため、Swiftユーザーで無い人は、検査例外という言葉をみた瞬間に興味を失ってしまうため、その詳細がなかなか世の中に伝わっていないと感じています。一方、私はこんなSwiftのエラーハンドリングをとても気に入っていて、様々な言語の進化の歴史を踏まえた産まれた最も優れた最先端の仕様だと思っています。この記事ではその考えを説明します。 Javaのエラーハンドリング Javaは検査例外を持っています。これにより、あるメソッドがエラーを送出するかどうかを関数のシグネチャとして静的に表明できます。 // 検査例外の例

Exponential time complexity in the Swift type checker
This article will look issues surrounding a Swift compiler error that repeatedly forces me to rewrite my code: error: expression was too complex to be solved in reasonable time; consider breaking up the expression into distinct sub-expressions I’ll look at examples that trigger this error and talk about negative effects beyond compiler errors that are caused by the same underlying issue. I’ll look
Building an iOS App in Rust, Part 1: Getting Started with Rust - Big Nerd Ranch
Building an iOS App in Rust, Part 1: Getting Started with Rust Editor’s note: This is the first post in our series on building an iOS app in Rust. The vast majority of apps that get developed for iOS and Android are written in the native languages provided by the platform: Swift or Objective-C on iOS, and Java on Android. I don’t expect that to change any time soon; however, sometimes there’s a ne
Prototyping Animations in Swift / iOS 8
With every release, Apple have been making developer tools easier and more productive to use. Now with Xcode 6 and iOS 8, Apple have created a new programming language called Swift that is not only more powerful, but also has a syntax that designers will probably feel a lot more comfortable with compared to Objective-C. If you’ve ever wanted to learn enough programing to create rich prototypes and
Function hooking in Swift
I spent the last two weeks being excited about the new things Apple showed us at WWDC’14. And the language Swift is one of the most interesting inventions. I'm not sure why do I need to learn it (because, hey, it even uses Objective-C runtime so why threw my C away?), but learning new stuff is usually cool, so why not? My first „Hello, world!“ program was a port of rd_route() to Swift — since one
Piping with Swift
Lately I’ve been playing with Apple’s newborn Swift quite a lot. I have to say that I am really impressed, and except for few things that I hope will be smoothed in the next months (years?), I find Swift really enjoyable and readable. However, there is one feature that I really miss. Something that I daily use with slightly different syntaxes in Sh, Haskell, Julia and Elixir: the pipe! # Can we im
