The decision followed the expected work to adopt React Native's New Architecture and improvements in AI coding models, which Shopify said made a clean-slate native rewrite more attractive than migration. ### Source excerpt Shopify recently announced it is abandoning React Native to rewrite its flagship apps in Swift and Kotlin. With the significant jump in the quality of AI models, Head of Mobile Mustafa Ali reassessed Shopify's commitment to React Native, estimating that the benefit/cost ratio of maintaining native codebases across mobile platforms was now above that of using an abstraction layer.

Swift aims to be a great choice across the stack, from apps and servers to systems code, embedded devices, and the browser. This release deepens that support, and makes everyday code easier to write. Highlights include: Swift Build is now the default in Swift Package Manager, so your projects build the same way on Linux, macOS, and Windows. Subprocess reaches 1.0, a stable, cross-platform way to run and interact with other programs from Swift, from command-line tools to streaming processes. Interoperability reaches further, with Swift's Span now bridging directly with C++20's std::span, and Swift/Java interop extending its async and callback support. Swift runs faster in the browser, with WebAssembly bridging through JavaScriptKit up to 40 times faster, and the Wasm SDK available directly from Swift.org. Embedded Swift grows more capable, with support for existential types and richer error handling for microcontroller-class targets. Performance improves while maintaining memory safety, with new array types that hold non-copyable elements without copy-on-write overhead, and the new Iterable protocol for iterating without copies. There's so much more. Read on for a detailed guide to the new changes, or see the Swift Evolution dashboard for the full list of proposals in Swift 6.4. Simpler and clearer code Swift 6.4 streamlines your day-to-day programming to make your code simpler and clearer. More natural optional some and any types. When writing an optional some or any type, you no longer have to wrap the type in parentheses. Instead of (some Rocket)?, you can simply write some Rocket? (SE-0521). Source-level control over compiler warnings. When you need to control the behavior of warnings in your project, such as suppressing warnings or promoting them to errors, you can now define the warning behavior directly in your code using the new @diagnose attribute (SE-0522). Clarify which API to use when multiple libraries conflict.

The article explains that AI agents can now handle enough implementation, translation, testing, and review work to reduce the cost of maintaining separate platforms. It also notes the planned relocation or archival of Shopify's React Native libraries. ### Source excerpt Native is now the future of mobile at Shopify Shopify are moving from React Native back to separate Swift and Kotlin codebases for their native apps, for the exact reason you would expect: We decided to switch from native to React Native in 2020 for three reasons: Stop building the same features twice Allow developers to work across the stack Spend less time chasing feature parity and more time shipping value [...] Native still means building and maintaining software on two platforms, that cost has not disappeared. What changed is that agents can now do enough of the implementation, translation, testing, and review work that it's no longer the deciding factor it was in 2020. It's a well-written post, which gives full credit to React Native as a great platform for the six years they were using it. Shopify are the maintainers of three significant React Native libraries: react-native-skia, flash-list, and restyle. The first two are finding new homes; the third "has a smaller user base than our other libraries" and will be archived at the end of 2026.

It describes replacing hand-written bindings with generated animation binding code from asset files so the compiler can enforce the contract and reduce reliance on tribal knowledge. ### Source excerpt Seth Sandler There's a bug we never shipped, and it kept me up anyway. Here's how it goes: a designer renames a property from purchaseCount to purchase_count inside an animation file. Every place our Swift code references that property is a string literal. The build stays green. Code review passes; nothing in the diff even mentions animations. And the celebration animation at the heart of our live auctions silently stops firing, in production, in front of a live audience. Nothing stood between us and that outcome except everyone remembering to be careful. And the strings were only the most visible tripwire. Driving our animation runtime correctly also meant knowing things the compiler never checks: call order, load timing, which properties were designer-internal and untouchable, how not to leak memory. Every engineer touching an animation had to know all of it, and every new animation was another chance to get it wrong. If you've done animation work on iOS, some version of this unease is familiar. This post is the story of how we defused it: by generating the entire animation binding layer from the asset files themselves, so the compiler enforces the contract and the generated code encodes the nuance. The methodology isn't specific to our stack, our vendor, or our app. If your code talks to any designer-owned asset through string literals and tribal knowledge, you can build this too. Why hand-rolled animation code collapses Our first instinct, like every iOS team's, was to build the animations ourselves. SwiftUI has withAnimation. Core Animation has CAKeyframeAnimation. We'd shipped complex UI before. How hard could it be? The animation we were building wasn't a loop. It was state-driven: it needed a user's avatar, their name, a running count that ramps up the visuals, and different behavior depending on who's watching. Each input changes the intro, the escalation, the outro. In native Swift, that decomposed into: State explosion.

It also discusses the effects of dynamic features on runtime performance and code size. ### Source excerpt Embedded Swift is a subset of Swift that's designed for low resource usage, making it capable of running on constrained environments like microcontrollers. Using a special compilation mode, Embedded Swift produces significantly smaller binaries than regular Swift. While a subset of the full language, the vast majority of the Swift language works exactly the same in Embedded Swift. Additional information is described in the Embedded Swift vision document. Embedded Swift is evolving rapidly. Following our updates on Embedded Swift improvements in Swift 6.3 late last year, this post describes a number of additional improvements made in the upcoming Swift 6.4 release. You can try them out today with a Swift development snapshot. Language improvements Embedded Swift continues to expand its subset of the language to include more aspects of "full" Swift, making it easier than ever to bring compatibility with Embedded Swift to existing Swift code bases. Many of these features have some dynamic aspect to them, meaning that they have an impact on runtime performance (for example, due to indirect calls) and code size (due to requiring additional metadata). However, this impact only occurs where these dynamic language features are actually used: code that is highly sensitive to code size and performance can choose to avoid them, for example by enabling warnings in the PerformanceHints diagnostic group. Generalized support for existential (any) types any) types section" href="#generalized-support-for-existential-any-types"> Embedded Swift previously only supported existential (any) types that had an AnyObject constraint, meaning they could only be used with class instances. Now, all any types are available in Embedded Swift, including Any itself. For example: protocol P { func method() } extension Int: P { func method() { print("\(self) is here") } } let a: any P = 17 a.method() // prints "17 is here" The Embedded Swift generics compilation model, which requires that all generic ## Kodebits Day 78: Switch Where Clause \[FREE\] DevFeed: [Kodebits Day 78: Switch Where Clause \[FREE\]]() Original publisher: [Read original article]() Published: 2026-08-18T18:00:44Z Content type: tutorial Language: en Sources: [Kodeco | High quality programming tutorials: iOS, Android, Swift, Kotlin, Unity, and more]() Topics: [Swift]() Tags: [article](), [development](), [free](), [swift]() ### AI overview A short coding challenge for practicing Swift switch statements with a where clause. ### Source excerpt Practice switch statements with a short swift challenge. ## Kodebits Day 77: Optional flatMap \[FREE\] DevFeed: [Kodebits Day 77: Optional flatMap \[FREE\]]() Original publisher: [Read original article]() Published: 2026-08-17T16:00:42Z Content type: tutorial Language: en Sources: [Kodeco | High quality programming tutorials: iOS, Android, Swift, Kotlin, Unity, and more]() Topics: [Swift]() Tags: [article](), [development](), [free](), [swift]() ### AI overview A short, free Kodeco challenge for practicing Swift optionals with flatMap. ### Source excerpt Practice optionals with a short swift challenge. ## Swift Testing explained with code examples DevFeed: [Swift Testing explained with code examples]() Original publisher: [Read original article]() Author: Antoine van der Lee Published: 2026-08-17T08:51:15Z Content type: tutorial Language: en Sources: [SwiftLee]() Topics: [Swift](), [Xcode](), [Code]() Tags: [examples](), [net-conf](), [swift](), [swift-testing](), [testing](), [xcode]() ### AI overview This tutorial introduces Swift Testing, the modern Swift testing framework built around expressive macros such as @Test, #expect, and #require.
