I can't figure how to install it
Here's google post:
You can use the following free options directly inside Xcode 27:1. Built-in On-Device Predictive Code CompletionApple provides a free on-device, on-chip model that runs entirely locally on your Mac.Cost: 100% Free (no internet connection or subscription required).How it works: It uses Apple Silicon to predict and autocomplete your Swift code instantly as you type.Setup: Go to Xcode > Settings > Intelligence and ensure local code completion is toggled on.2. Free-Tier Cloud Models (ChatGPT, Claude, & Gemini)Xcode 27 explicitly features a native two-tier intelligence system. For simple completions, it uses your local chip. For complex planning, multi-turn conversations, and writing autonomous unit tests, it integrates directly with cloud providers. You can utilize the free tiers of these services:Anthropic Claude: You can generate a free API key from the Anthropic Developer Console to power Xcode 27’s coding agents.OpenAI ChatGPT: You can hook Xcode directly into OpenAI's free-tier API allowance.Google Gemini: Xcode 27 natively supports Google's ecosystem, allowing you to use a free Gemini API key.Setup: Navigate to Xcode > Settings > Intelligence, select your cloud provider, and paste your free API key.3. Fully Local Open-Weight Models via OllamaIf you want to handle complex agent tasks without data leaving your Mac, you can connect Xcode 27 to local open-source models. This requires an Apple Silicon Mac.Recommended Models: qwen2.5-coder (highly recommended for Swift and SwiftUI) or llama3-coder.Setup:Download and run Ollama.Pull the model via your Mac terminal (ollama run qwen2.5-coder).Use an Xcode 27 compatible local-host bridge tool or local API endpoint under the "Custom Provider" option in Xcode's Intelligence settings to link Ollama's local port (localhost:11434) straight into your workspace.Xcode 27 Agent SkillsWhen using these models in Xcode 27, they will automatically ingest Apple's native Agent Skills (like the SwiftUI Specialist Skill). This means even a generic free model will receive Apple's optimized context rules to write better, modern Swift 6 code.Are you looking to use the model mostly for inline code autocompletion or for the new conversational agent features (like having the AI autonomously write tests and fix bugs in your workspace)? I can walk you through the exact setup steps for either.19 sitesXcode 27 Beta Release Notes | Apple Developer DocumentationOverview.
