What is Swift Formatter?
Swift Formatter is a specialized tool designed to format and beautify Swift code according to Apple's Swift API Design Guidelines and best practices. Swift is Apple's modern programming language used for iOS, macOS, watchOS, and tvOS development, requiring consistent formatting for maintainable and professional applications.
Our Swift formatter ensures your code follows established Apple conventions and maintains consistency across your development team and iOS projects, embracing Swift's principles of safety, performance, and expressiveness.
