iOS is the world’s most advanced mobile operating system. With iOS 13, you can now use cutting-edge technologies to build unparalleled augmented reality experiences with ARKit 3, Reality Composer, and RealityKit. Core ML 3 and the new Create ML app help you deliver personalized app experiences quickly and easily with industry-leading, on-device machine learning. Users can sign in to your apps with their Apple ID. And you can take advantage of the latest improvements to Siri Shortcuts, camera APIs, and other exciting technologies.

Dark Mode

Dark Mode has been beautifully integrated throughout iOS, and Xcode 11 gives you powerful tools to easily support dark mode in your apps. Quickly switch your designs and previews between light and dark in Interface Builder, and preview both modes in SwiftUI, even side-by-side. Asset catalogs let you label assets and named colors with variants for light and dark. You can even switch your app in and out of dark mode while debugging.

Augmented Reality

ARKit 3 delivers an incredible awareness of people with the ability to integrate human movement into your app, the new People Occlusion feature that lets AR content realistically pass behind and in front of people in the real world, and much more. It’s easy to prototype and produce AR experiences with Reality Composer — a powerful new app that lets you easily create AR experiences, and RealityKit — a new high-level augmented reality framework.

Siri

Use the latest advances in Siri to provide an interactive voice experience with follow-up questions, additional shortcut customization, and audio content playback. Your apps can let Siri know when a user makes a reservation so Siri can remind them to check in, provide directions in Maps, add the event to Calendar, and more. And with the Shortcuts app built in to iOS 13, it’s even faster for users to find, use, and combine shortcuts.

Machine Learning

With on-device model training and a gallery of curated models, there’s never been a better time to take advantage of machine learning. Core ML 3 seamlessly takes advantage of the CPU, GPU, and Neural Engine to provide maximum performance and efficiency, and lets you integrate the latest cutting-edge models into your apps. The new Create ML app lets you build, train, and deploy machine learning models with no machine learning expertise required.

SwiftUI

Better apps. Less code.
SwiftUI is an innovative, exceptionally simple way to build user interfaces across all Apple platforms with the power of Swift. Build user interfaces for any Apple device using just one set of tools and APIs. With a declarative Swift syntax that’s easy to read and natural to write, SwiftUI works seamlessly with new Xcode design tools to keep your code and design perfectly in sync. SwiftUI is truly native, so your apps directly access the proven technologies of each platform to beautifully implement everything users love about the Apple ecosystem.
