A beautiful new software design brings more focus to content, and delivers more expressive and delightful experiences across iOS 26, iPadOS 26, macOS Tahoe 26, watchOS 26, and tvOS 26,1 while keeping them all instantly familiar.

The Foundation Models framework joins a suite of tools that allow developers to tap into on-device intelligence, and Xcode 26 leverages large language models like ChatGPT, giving them access to Xcode’s Coding Tools and other intelligent features.

These new resources join the extensive and continuously evolving set of technologies Apple offers developers, including over 250,000 APIs that enable developers to integrate their apps with Apple’s hardware and software features.

These APIs span a wide range of capabilities, such as machine learning, augmented reality, health and fitness, spatial computing, and high-performance graphics. With each platform release, Apple expands and refines its technologies and tools to assist developers in bringing their ideas to life and delivering rich, responsive, and optimized experiences across Apple platforms.

“Developers play a vital role in shaping the experiences customers love across Apple platforms,” said Susan Prescott, Apple’s vice president of Worldwide Developer Relations. “With access to the on-device Apple Intelligence foundation model and new intelligence features in Xcode 26, we’re empowering developers to build richer, more intuitive apps for users everywhere.”

New Design with Liquid Glass

The elegant new design gives developers the opportunity to make their apps more expressive and delightful, while being instantly familiar. It’s crafted with a new software-based material called Liquid Glass, which combines the optical qualities of glass with a sense of fluidity.

This gorgeous new material extends from the smallest elements users interact with every day — like buttons, switches, sliders, text, and media controls — to larger elements, including tab bars and sidebars for navigating apps.

Native frameworks like SwiftUI give developers everything they need to adopt the new design in their apps.

The universal design allows developers to bring greater focus to their users’ content, establishing a consistent experience when developing across Apple’s platforms.

With the all-new Icon Composer app, developers and designers are empowered to create visually captivating app icons that enhance their app’s identity.

This powerful tool helps create a consistent visual identity for app icons by annotating layers for multiple rendering modes, with advanced features that include blurring, adjusting translucency, testing specular highlights, and previewing icons in various tints.

Foundation Models Framework

With the Foundation Models framework, developers will be able to build on Apple Intelligence to bring users new experiences that are intelligent, available when they’re offline, and that protect their privacy, using AI inference that is free of cost.

The framework has native support for Swift, so developers can easily access the Apple Intelligence model with as few as three lines of code.

Guided generation, tool calling, and more are all built into the framework, making it easier than ever to implement generative capabilities right into an existing app.

For example, Automattic is using the framework in its Day One journaling app to bring users privacy-centric intelligence features.

“The Foundation Model framework has helped us rethink what’s possible with journaling,” said Paul Mayne, head of Day One at Automattic. “Now we can bring intelligence and privacy together in ways that deeply respect our users.”

Xcode 26

Xcode 26 is packed with intelligence features and experiences to help developers make their ideas a reality.
Developers can connect large language models directly into their coding experience to write code, tests, and documentation; iterate on a design; fix errors; and more.

Xcode has built-in support for ChatGPT, and developers can use API keys from other providers, or run local models on their Mac with Apple silicon, to choose the model that best suits their needs.

Developers can start using ChatGPT in Xcode without needing to create an account, and subscribers can connect their accounts to access more requests.

Xcode 26 comes with additional features to keep developers focused and productive, like a redesigned navigation experience, improvements to the localisation catalog, and improved support for Voice Control to dictate Swift code and navigate the Xcode interface entirely by voice.

App Intents

App Intents lets developers deeply integrate their app’s actions and content with system experiences across platforms, including Siri, Spotlight, widgets, controls, and more.

This year, App Intents gains support for visual intelligence.

This enables apps to provide visual search results within the visual intelligence experience, allowing users to go directly into the app from those results.

For instance, Etsy is leveraging visual intelligence to enhance the user experience in its iOS app by facilitating faster and more intuitive discovery of goods and products.

“At Etsy, our job is to seamlessly connect shoppers with creative entrepreneurs around the world who offer extraordinary items — many of which are hard to describe. The ability to meet shoppers right on their iPhone with visual intelligence is a meaningful unlock, and makes it easier than ever for buyers to quickly discover exactly what they’re looking for while directly supporting small businesses,” said Etsy CTO Rafe Colburn.

Swift 6.2

Swift 6.2 introduces powerful features to enhance performance, concurrency, and interoperability with other languages like C++, Java, and JavaScript. And now, in collaboration with the open-source community, Swift 6.2 gains support for WebAssembly.

Building upon Swift 6’s strict concurrency checking, Swift 6.2 simplifies writing single-threaded code.

Developers can now configure modules or individual files to run on the main actor by default, eliminating the need for additional annotations.

Containerisation Framework

The Containerisation framework enables developers to create, download, or run Linux container images directly on Mac. It’s built on an open-source framework optimised for Apple silicon and provides secure isolation between container images.
