Xcode 16
Xcode 16 sets a new standard for developer productivity, offering features and performance enhancements that empower developers to build exceptional apps faster than ever before.
Swift Assist serves as a companion for all of a developer’s coding tasks, so they can focus on higher-level problems and solutions. It’s seamlessly integrated into Xcode, and knows the latest software development kits (SDKs) and Swift language features, so developers will always get the latest code features that blend perfectly into their projects. With Swift Assist, tasks like exploring new frameworks and experimenting with new ideas are just one request away. Swift Assist uses a powerful model that runs in the cloud — and like all
The new predictive code completion engine in Xcode uses a unique model specifically trained for Swift and
Xcode previews now offer a new dynamic linking architecture that uses the same build artifacts for previews and code execution, making for a smoother and more productive workflow when switching between the two.
Additional enhancements to testing environments in Xcode 16 make it easier than ever for developers to see how their apps perform in real-world conditions from the moment they begin building them. For example, developers can now localize and test their apps’ privacy policies, license agreements, and subscription group display name.
Swift 6
Swift 6 introduces new capabilities aimed at enhancing developer productivity and code clarity. As multicore architectures have made devices more powerful, Swift has continually added features to make concurrent programming easier. Swift 6 introduces compile-time data-race safety, which diagnoses concurrent access to memory across a developer’s project at compile time. This advancement allows errors to be caught and fixed with minimal changes to the entire codebase, enhancing code safety and maintainability for the future.
WWDC24 marks the 10th anniversary of Swift. Since its launch, Swift has empowered developers to create high-quality experiences across Apple’s ecosystem. Today, nearly 1 million apps use Swift, and it’s utilized throughout Apple’s software stack — from apps and frameworks, all the way down to firmware like Secure Enclave.
A decade in,
Swift Testing
The new Swift Testing framework offers developers expressive APIs that make it simple to write tests. It’s cross-platform and easy to learn, so developers can use it to write tests for a variety of platforms and domains. The framework also includes a flexible tagging system to help developers organize their tests and test plans. Swift Testing is designed for many Swift use cases, from apps to servers.
Game Porting Toolkit 2
With the introduction of Game Porting Toolkit, developers have been able to bring their games to
visionOS 2
New volumetric APIs give developers more control over how 3D objects appear in their apps, and allow even the most complex spatial apps to run side by side for the ultimate multitasking experience. TabletopKit makes it easy for developers to build spatial app experiences that anchor to flat surfaces, like manufacturing workstations or board and card games. RealityKit® simplifies development for apps that support multiple
Developers can more easily create beautiful and immersive environments within their apps through new APIs, improved tooling, and a simplified development process. It’s also even easier to develop incredible spatial SharePlay™ experiences, and developers without
New enterprise APIs will help enterprises and business developers supercharge their workflows in healthcare, manufacturing, aerospace, automotive, and beyond.
Additional Platform APIs
Developers can adopt the new Controls API to let users accomplish even more tasks from even more places, such as to quickly unlock their vehicle or open their favorite third-party camera right from the Control Center.
AccessorySetupKit allows developers to seamlessly and securely pair Bluetooth accessories through their app without relying on access to all nearby Bluetooth accessories, keeping other devices private.
With updates to the Smart Stack on
Developers also now have access to a new watchOS double tap API so they can assign the gesture to key parts of their
TestFlight
TestFlight® helps developers collect valuable beta feedback from testers to improve an app throughout the development and release process. With improvements to the TestFlight invitation and enrollment experience, developers will be able to engage testers by device and OS to receive higher-quality feedback for how to improve their apps.
TestFlight invitations will include the beta app’s description, app category, and optional screenshots to highlight new features and content for prospective testers. New metrics help developers evaluate engagement with public links and view invitation acceptances or declines.
For over 15 years, the App Store® has made it easy for developers to distribute their apps and games to people all over the world and grow their businesses. This year, the
New featuring nominations let developers easily nominate their apps’ upcoming content and enhancements for consideration to be featured on the
Custom product pages enable developers to showcase different content and features that are available in their apps. Now, with custom product page deep links, developers can seamlessly direct people from a particular custom product page on the
For subscription apps, developers can encourage former subscribers to resubscribe with new win-back offers. Eligible customers can discover these offers across the
Enhancements to StoreKit® views give developers new options to organize and present in-app purchases.
App Analytics has been expanded to help developers get even more insight into their business and their apps’ performance. Reports now include hundreds of new metrics that enable developers to find opportunities for improvement.
App Store Connect
The App Store Connect app for iOS and iPadOS® features an updated user interface and introduces a new way for developers to promote their apps’ special moments. Whether they’re launching a brand-new app or shipping an exciting new app update, developers can now effortlessly generate marketing assets from App Store Connect to share directly onto their social channels. If an app has been featured as App of the Day, developers will receive a push notification from App Store Connect inviting them to create a special marketing asset to commemorate the moment.
Today’s updates join an ever-growing abundance of tools, technologies, and resources
