Apple Intelligence and Machine Learning

The 27 platform releases include powerful new developer features that supercharge apps with AI capabilities. App Intents can connect your app with Siri, Spotlight, and Shortcuts. Foundation Models gives you a standard interface to perform powerful AI tasks across Apple-provided and third-party models. Core AI lets you connect your own models into the Apple tools as first-class providers. And the Evaluations framework provides a standard interface to evaluate your app’s intelligence-powered features.

Siri, Intents, and Spotlight

Your app can integrate with Apple Intelligence in the 27 releases across Apple platforms by leveraging App Intents, which make the core features of your app available to Siri, Spotlight, and Shortcuts. Widgets and Live Activities also interact with your core app through its intents.

Read the new Getting started with the App Intents framework guide to acclimate yourself to app intents. And the new Creating your first app intent article gets you familiar with using intents in your own code.

Read Testing your App Intents code to discover how the new App Intents Testing framework makes it easier than ever to test your intents to ensure they behave correctly across different user experiences.
Messaging apps can use the new Suggested Actions framework to privately and securely present actions next to messages. The system can intelligently discover useful information in message text and offer to add an event to the calendar, or add a task to Reminders, or open a location in Maps.
Use the new Media Intents framework to enable your media player app to handle Siri requests. Siri turns whatever phrase someone says into an AudioSearch type that is sent to your app for handling. The Responding to audio search and playback requests article shows how to add this capability into your own apps.
Use App entities types to give additional information about your app to Siri and Apple Intelligence. Read Making app entities available in Spotlight to see how to make that information available to Spotlight, as well.

Learn to use the Visual Intelligence framework on iOS, iPadOS, and now macOS by reading Integrating your app with visual intelligence. This enables your app to analyze image data from the camera to identify places and objects.

Foundation Models

The 27 platform releases add powerful new API to the Foundation Models framework. Developers can now use a single, standard interface to connect to all their models – from Apple’s on-device models to the powerful Private Cloud Compute hosted models. Frontier model providers can use the new LanguageModel protocol to vend a Swift package to bridge their powerful cloud-hosted models to the Foundation Models API. And with Core AI, Foundation Models API can access your own models, too.

Read Generating content and performing tasks with Foundation Models to get started building with Foundation Models, and create your first Prompt.
When your app can benefit from a larger, cloud-based model you can learn about Adding server-side intelligence with Private Cloud Compute. With Private Cloud Compute (PCC) you get a larger token context size, and stronger reasoning for handling more complex tasks. The PrivateCloudComputeLanguageModel class conforms to LanguageModel just as other frontier models do.
Foundation Models now supports image input as well as text, which you can learn to use by reading Analyzing images with multimodal prompting. The models can help you classify the image, summarize the content, generate accessibility descriptions on the fly, and more. Use an Attachment to send the image to the model along with your prompt.
Read Analyzing the runtime performance of your Foundation Models app to learn about optimization techniques that make the AI components of your app perform their best.
Learn how to measure and improve your prompts by reading Evaluating prompts to measure performance and improve model responses and develop a strategy about Managing the context window to optimize token use.

Core AI

The Core AI framework includes a set of tools that help you build, run, and deploy your own AI models within your app. Core AI also vends your custom AI models in a format that Foundation Models can use natively, so once adapted to Core AI, your models can interact with the same Foundation Models code you write when working with Apple’s own built-in models.

Designed for Apple silicon performance, Integrating on-device AI models in your app with Core AI details how to easily import third-party or your own models into your app, and achieve great performance.
Read Managing model specialization and caching to see how best to specialize your AI model, either in advance by Compiling Core AI models ahead of time, or cached on first use within the app.

Evaluations

The new Evaluations framework makes it easy to write intuitive Swift code to evaluate the behavior of your model, and validate your app’s behavior due to model results.
Read Evaluating language model responses to learn how you can build a strategy to evaluate your use of models within your app. Writing evaluations and creating comprehensive coverage is outlined in the article Designing effective evaluations.
Good evaluations require time spent Designing datasets to test your feature as well as Designing specific, measurable criteria in an evaluation suite. Reading Generating synthetic datasets can help you build synthetic data to quickly get even more coverage.

SwiftUI

Learn to use reorderable containers in your SwiftUI apps by reading Reordering items in lists, stacks, grids, and custom layouts. See how clean the code can look:

LazyVStack {
    ForEach(cranes) { crane in
        CraneRow(crane)
    }
    .reorderable()
}
.reorderContainer(
    for: Crane.self
) { difference in
    difference.apply(to: &cranes)
}
