Swift 2025-2026: main directions of language development for iOS and macOS

The Swift development team (Apple) has published an updated roadmap for language development for 2025–2026. The document covers both fundamental changes in the language itself and the evolution of the ecosystem: SwiftUI, the package manager, and Xcode tools. We analyze the key innovations that iOS and macOS developers should expect.

Main priorities of the roadmap

According to the plan, work is being carried out in five main directions:

Stability and backward compatibility — minimizing breaking changes when transitioning to new versions, especially important for large projects.
Performance — improving compilation time, optimizing generated code, reducing memory consumption.
Simplifying concurrency — refining async/await, actors, and strict data race checking (Strict Concurrency Checking).
Expanding Swift beyond Apple — improving support for server-side Swift (Vapor, Hummingbird), Windows, and Linux.
Evolution of SwiftUI — new visual components, improved integration with UIKit/AppKit, rendering performance.

What will appear in Swift 6.x (2025)

The release of Swift 6.0 is expected at the end of 2024 — beginning of 2025. The roadmap clarifies that the following minor versions (6.1, 6.2) will bring:

Full Borrowing and Ownership model — continued implementation of ownership semantics for safe memory management without a garbage collector.
Improved Macro System — support for macros for code generation in protocol extensions and types.
New capabilities for the package manager — support for binary frameworks, improved dependency caching.
Extended C++ interoperability support — will make it easier to use C++ libraries in Swift projects (relevant for macOS).

Evolution of SwiftUI and Xcode

Apple also announced changes in development tools:

SwiftUI 6 — components for working with 3D content (based on Metal) will appear, improved Accessibility support.
Xcode Predictive Code Completion — an ML model for autocompletion running locally on the device.
New tool for visual testing — recording and playback of UI tests with automatic code generation.

What does this mean for developers?

The roadmap shows that Swift is becoming a mature language, combining the performance of system programming with the convenience of high-level languages. For iOS/macOS developers this means:

More opportunities for writing safe multithreaded code.
Faster project compilation (especially relevant for large codebases).
A smooth transition to new versions without needing to rewrite all code.
Expanding the scope of Swift — from mobile applications to servers and scripts.

Follow updates on the official Swift.org repository and in Xcode beta. Plans may be adjusted, but the general vector is obvious: Swift strives to become a universal language for the entire ec
