Swift for C++ Practitioners: Move Semantics (douggregor.net)
Since their introduction in C++11, move semantics have been an integral part of programming in C++. Move semantics are implemented in C++ with rvalue references, which express the idea that the entity they refer to is temporary in nature (an rvalue in programming language speak) and effectively won't be used again later.

Apple's use of Swift and SwiftUI in iOS 18 (timac.org)
As with previous iOS versions, let’s analyze the built-in apps of iOS 18 to answer a few questions: How many binaries does iOS 18 contain? Which programming languages were used to develop these apps? How many apps are written in Swift? What percentage of apps use SwiftUI versus UIKit?

Native Swift on Android, Part 2: Your First Swift Android App (skip.tools)
Swift is Apple’s recommended language for app development, and with good reason. Its safety, efficiency, and expressiveness have made it easier than ever to build fast, polished, and robust apps for the Apple ecosystem. Recent stories about Swift on Windows and Swift on the Playdate highlight developers’ desire to take advantage of Swift on other platforms too. In this series, we explore writing native Swift apps for Android with Skip.

Watch Out for Counterintuitive Implicit Actor-Isolation (jaredsinclair.com)
I ran into some unexpected runtime crashes recently while testing an app on iOS 18 compiled under Swift 6 language mode, and the root causes ended up being the perils of using @unchecked Sendable in combination with some counterintuitive compiler behavior with implicit actor isolation.

Secure your URLSession network requests using Certificate Pinning (erezhod.com)
In an age where data breaches and cyber threats are on the rise, securing your app’s communication isn’t just a nice-to-have, it’s a must. This article will guide you through implementing a methodology called “Certificate Pinning” using Swift’s URLSession, a simple yet powerful way to safeguard your iOS and macOS apps from man-in-the-middle attacks. By the end, you’ll not only understand why this technique is critical but also how to integrate it seamlessly into your network requests.

Ask HN: What are the nice feature you need in a programming language? (ycombinator.com)
I'm developing a programming language, the keywords and features mostly based on Swift 5 but some additional features like, <p>1. async function will be called from no async function but no async/await keyword. If you want to block main thread then block_main() function will be used. block_main() /* operations */ unblock_main()<p>2. protocol can inherit another protocol(s) & protocol can confirm a class like swift.<p>3. no `let`. only `var`. compiler can optimize further.<p>4.

A Swift Toolchain for Android, Part 1: Setup, Compiling, Running, and Testing (skip.tools)
You may already be familiar with Skip as a tool for bringing your Swift iOS apps to Android. Skip takes a novel transpilation approach, where we integrate with the Xcode build system to convert your Swift code into Kotlin. This allows us to create an Android library for every build of your Swift package, or to launch an Android version of your SwiftUI app on every Xcode Run.
