1. Integration with other tools: JetBrains Space offers seamless integration with various JetBrains IDEs, such as IntelliJ IDEA, PyCharm, and WebStorm, enabling a smooth workflow for developers. On the other hand, Xcode is specifically designed for Apple's ecosystem, providing deep integration with iOS, macOS, watchOS, and tvOS development tools.

2. Platform support: JetBrains Space is a cross-platform collaboration tool, allowing teams to work together regardless of the operating system they use. In contrast, Xcode is exclusive to macOS, limiting its use to developers who work on Apple devices.

3. Version control system: JetBrains Space comes with built-in support for Git repositories and features like pull requests, code reviews, and branching, facilitating efficient code management. In comparison, Xcode primarily relies on Git for version control but lacks the comprehensive collaboration features found in JetBrains Space.

4. Project management capabilities: JetBrains Space provides robust project management tools, including issue tracking, roadmaps, and Agile boards, ensuring teams can effectively plan and execute their tasks. Conversely, Xcode focuses more on the development environment itself, with a priority on coding and debugging features.

5. Code analysis and quality tools: JetBrains Space offers code analysis tools like code inspections, duplication detection, and code coverage, helping developers maintain code quality standards. On the contrary, Xcode includes built-in tools like Instruments for performance analysis and XCTest for unit testing but may require additional plugins or integrations for comprehensive code analysis.

6. Collaboration features: JetBrains Space emphasizes team collaboration through features like chat, calendars, team directory, and code reviews, promoting communication and transparency within the development process. In contrast, Xcode provides limited collaboration tools, with a focus on individual development tasks and interactions within the Xcode environment.

In Summary, JetBrains Space and Xcode differ in terms of integration with other tools, platform support, version control system, project management capabilities, code analysis tools, and collaboration features, catering to different needs in the development workflow.
