Novidades no Xcode 27

The session previews four topics: workspace customization, new project workflows, coding agents, Device Hub, and post-launch tools.

The Xcode 27 toolbar has been redesigned with new controls, a coding agent entry point, and is now fully customizable with reorderable items.

A new Appearance panel lets you dial in colors and fonts with sliders, choose from preset themes, and assign per-project themes for quick visual identification.

Predictive issues now use a subtle appearance while typing to reduce distractions, upgrading to full-intensity warnings and errors only after a build.

Xcode 27 lets you instantly create untitled projects or open standalone Swift files with previews and playground results, making it easy to prototype on the fly.

Agent conversations now live in the editor pane with full tab and split support, plus a new /plan command to scope work before making any code changes.

Device Hub provides a unified window for running, inspecting, and evaluating your app across simulators and physical devices, including accessibility settings and iPhone Mirroring resize testing.

Coding agents in Xcode 27 can set up localization, create String Catalogs, and generate translations for multiple languages.

The redesigned Organizer surfaces high-impact issues first, adds storage and animation hitch metrics, introduces Metric Goals, and can generate agent-powered fix recommendations.

A new Top Functions view in Instruments quickly identifies the most expensive code paths, cutting investigation time when tracking down performance regressions.

Xcode Cloud now offers a streamlined onboarding flow to get builds and tests running automatically on every commit, with seamless TestFlight and App Store delivery.

A summary of Xcode 27's end-to-end support for the app lifecycle, from prototyping and agents to localization and post-launch issue resolution.
