PRO

• Tuist own explanation of its advantages
• Tuist is developed in Swift (no additional dependencies needed for installation)
• Fast bug fixes since Tuist is open source and developed in a community driven way
• Developers can write configuration files in Swift ❤️
• Code for setting up multiple projects can be shared using Project-Description-Helpers
• Project configuration and build settings can be documented
• External dependencies can be integrated in an easy way. Carthage and SPM are supported too.
• The workspace and project file can be removed from git which leads to a high reduction of merge conflicts and a smoother development process.
• Supports the creation of release pipelines for GitHub Actions and Bitrise.
