WWDC 2025 features in Alex Sidebar - Foundation Models, Liquid Glass design, and new APIs Alex Sidebar now supports the contexts for the features announced at WWDC 2025, including the Liquid Glass design system, and the latest APIs. This guide shows you how to use these new features in your apps.

​
Key Announcements

Liquid Glass Design

A new design system with translucent, adaptive interfaces

Foundation Models

Access Apple Intelligence’s language model on-device with just a few lines of code

SpeechAnalyzer API

Faster and better speech recognition with improved accuracy

SwiftUI Performance

Faster list loading and updates on macOS

​
Commands in Alex Sidebar

There are new commands to help you implement the new design and work with the latest APIs. Use these command tags to access specific capabilities:

​
@WWDC25 Mode

Access the latest Apple documentation related to WWDC 2025 by prefixing your requests with @WWDC25. For example, to get the context for the latest documentation for the SpeechAnalyzer API, you can use the following command: 
@WWDC25 Implement the new SpeechAnalyzer API for real-time transcription
This mode gives Alex the context of:
  • All iOS 26, macOS 26, and visionOS 26 APIs
  • Liquid Glass design implementation
  • New SwiftUI features like Rich Text Editor and 3D Charts
  • Performance optimizations and best practices
Example Uses: 
@WWDC25 Create a 3D chart in the given view with the new Charts API
@WWDC25 Implement the new WebKit APIs for in-app browsers

​
@Foundation Models Command

Use Apple’s language model directly in your apps. Here is an example of how to use the @Foundation Models command: 
@FoundationModel Create a suggestion system using the new Foundation Models API for generating name recommendations
Example Implementation: 
import FoundationModels

// Access Apple's on-device foundation model with just a few lines
let session = try await LanguageModelSession()

// Generate structured data from natural language
let prompt = "Create a daily journal entry from these notes: \(userNotes)"

let response = try await session.respond(
    to: prompt,
    generating: JournalEntry.self
)

// The model runs entirely on-device, protecting user privacy
let journalEntry = response.content

​
@Liquid Glass Command

Update your UI with the new Liquid Glass design system. Here is an example of how to use the @Liquid Glass command: 
@Liquid Glass Update the custom button to use the new Liquid Glass design

​
Combining Commands

Use multiple commands together for better results. Here is an example of how to use the @WWDC25, @Liquid Glass, and @Foundation Models commands together: 
@WWDC25 @Liquid Glass @Foundation Models 
Create an AI-powered notes app with speech transcription and the new design system
This combination:
  1. Uses SpeechAnalyzer for transcription (@WWDC25)
  2. Applies Liquid Glass design throughout the app (@Liquid Glass)
  3. Uses Foundation Models for summarization (@Foundation Models)
