Xcode offers the tools you need to develop, test, and distribute apps for Apple platforms. It provides a complete development environment that supports the entire app creation workflow from initial coding to final distribution.

Xcode includes predictive code completion powered by Apple silicon, which uses an on-device machine learning model trained for Swift and Apple SDKs. It supports interacting with code using large language models including Anthropic's and OpenAI's advanced coding models and agents. The platform features Coding Tools for writing code and documentation or fixing errors directly from the source editor. Xcode Previews allow developers to quickly visualize changes in SwiftUI, UIKit, and AppKit views using the preview canvas.

Simulator enables rapid prototyping by testing apps in simulated environments across Apple devices and OS versions. It provides access to performance testing, advanced debugging tools, and simulation of various scenarios like location changes and network throttling. Xcode includes the Swift Testing framework for writing unit tests and XCTest for UI tests and performance measurement.

Xcode Cloud is a continuous integration and delivery service built into Xcode that accelerates development by providing cloud-based tools for building apps, running automated tests in parallel, and delivering apps to testers. The debugger helps inspect app behaviors, pause execution at breakpoints, inspect memory usage, and monitor variables. Instruments provides real-time insights into CPU, disk, memory, and GPU performance with graphical tracks over time.

Xcode helps developers catch issues early and deliver high-quality apps by providing comprehensive testing resources. The Organizer allows managing app development from start to finish including testing, debugging, building, and deploying. Developers can analyze anonymized performance data from users to assess launch times, memory usage, UI responsiveness, and battery impact.
