GitHub Copilot is evolving again—this time with deep, native integration for Xcode. We’re introducing a new generation of agent-driven capabilities designed to streamline workflows, accelerate development, and keep you focused on building great apps for Apple platforms. This update unifies Copilot’s cross-IDE experience and brings structured automation to the heart of your Xcode environment.

Introducing Advanced Agentic Features

2025 marks the rise of intelligent agents. Developers need flexibility and precision—both in how they interact with agents and how those agents adapt to their coding style. After launching Custom Agents in VS Code, we’re now bringing them to Xcode with Custom Agents, Subagents, and the powerful Plan Mode.

Custom Agents – personalize your Copilot

Configure Copilot to match your workflow. Define instructions, constraints, and tools so Copilot works the way you do—whether you’re building SwiftUI interfaces or managing complex iOS projects.

Subagents – precision through isolation

Each subagent runs in a clean, focused context, reducing noise and improving accuracy. This reduces distractions and improves reasoning for actions like fixing tests, refactoring code, or generating documentation. In Agent Mode, Copilot automatically invokes your pre‑defined subagents when appropriate, so the right capability is applied at the right time—no manual routing required.

Plan Mode – structured execution for complex tasks

Plan Mode transforms Copilot into a strategic problem-solver. It breaks down multi-step challenges into clear, sequential actions—planning, executing, and validating—so you can tackle big engineering tasks with confidence.

Next Edit Suggestions

Stay in flow with proactive recommendations for your next code edits, improvements, or cleanup—helping you iterate faster without losing context.

In addition, GPT‑5.1 models, including GPT‑5.1‑Codex and Codex‑Mini, are now available in Copilot for Xcode. These models bring significant enhancements to chat responsiveness, agent-driven workflows, and code generation accuracy—helping developers plan, execute, and iterate more efficiently within Xcode.
