Develop for iOS

The Foundation Models framework is a native Swift API that gives you direct access to Apple Foundation Models — on device and in Private Cloud Compute* — as well as any model provider with a Swift package conforming to the Language Model protocol.

From theremultimodal prompts and on-device Vision framework tools let your app reason about images alongside textwhile Dynamic Profiles let you swap modelstoolsand instructions within a continuous session so your app's intelligence can adapt in real time. Then use the Evaluations framework to ensure your AI features work reliably across dynamic conditions.

The App Intents framework connects your app to Apple Intelligence and Siri AI through schemas — recognizable structures built on years of language model training — that make your app's content discoverable and its capabilities available through natural language with less code.

Entity schemas contribute your content to the Spotlight semantic index for personal context understandingwhile intent schemas let people take action on that content naturallywith no specific phrases to define and no code changes needed as Siri's language understanding evolves. The View Annotations API extends this further with on-screen awarenessletting you map views to entities so people can reference and act on what's in front of them conversationally.

With Live Activitiesyour app can provide up-to-dateglanceable information — like weather updatesa baseball scoreor how long it’ll be until dinner is delivered — right on the Lock Screen or Dynamic Island.

For apps with frequent content and status updates that go beyond the existing push notification systemLive Activities can be a more flexible way to keep people updated about live eventsactivitiesor tasks over a couple of hoursbecause in addition to frequently updating datathey offer a way for people to interact with the information.

A widget elevates and displays a small amount of timely and relevant information from your app or game so people can see it at a glance in additional contexts — without requiring them to open your app.

The system can display widgets in different places depending on a person’s device. In iOS and iPadOSwidgets appear on the Home Screenin Today Viewand on the Lock Screen. The widget gallery also supports widget stacksincluding a Smart Stack. In a Smart Stackthe stack automatically rotates its widgets to display the widget that’s most likely to be relevant in the current context.

Create local and push notifications that give people timelyhigh-value information they can understand at a glance. Notifications are great for keeping people informed with relevant contentwhether your app is running in the background or inactive. Notifications can display a messageplay a distinctive soundor update a badge on your app icon. And with the broadcast capability from the Apple Push Notification service (APNs)you can deliver updates to your Live Activities at scaleand reach all your subscribed users by sending just a single push notification.

Metal gives you directlow-overhead control of the GPU so you can build visually rich games and run them at maximum efficiency on Apple silicon. Run ML inference directly in your shaders to compute lightingmaterialsand geometry in real time. Use MetalFX to boost performance by upscaling lower-resolution content and save GPU time. Game Porting Toolkit 4 dramatically cuts the time and cost of bringing your game to Apple platforms with new agent skills and command-line Metal tools that let AI coding agents drive every step of the porting process.
