Worked on the swiftlang/swift-format repository to enhance code clarity and maintainability within the formatting pipeline. Focused on refactoring the PrettyPrintBuffer component by replacing a hardcoded newline ASCII value with a named constant, thereby clarifying intent and reducing the risk of future errors. This change improved code readability and supported long-term stability efforts in the SwiftFormat project. Utilized Swift and applied code refactoring and readability improvement skills to ensure that future contributors can more easily understand and modify the formatting logic. The maintenance-focused approach stabilized core formatting behavior and simplified the process for future bug fixes and feature development.
