CSwiftV
A CSV parser for Swift that conforms to RFC 4180 standards for reliable CSV file handling.
What is CSwiftV?
CSwiftV is a CSV parsing library written in Swift that conforms to the RFC 4180 specification, providing a standards-compliant way to parse comma-separated values data. It solves the problem of inconsistent CSV parsing by implementing the closest thing to an official CSV specification, ensuring reliable handling of quoted fields, line breaks, and other edge cases.
Swift developers working with CSV data in iOS, macOS, or server-side applications who need reliable, standards-compliant parsing without external dependencies.
Developers choose CSwiftV because it provides a simple, native Swift implementation that strictly follows the RFC 4180 standard, ensuring consistent behavior across different CSV files and avoiding the parsing inconsistencies found in many CSV libraries.
Overview
A csv parser written in swift conforming to rfc4180
Use Cases
Best For
- Parsing CSV files exported from databases or spreadsheets in Swift applications
- Processing configuration or data files in iOS/macOS apps that use CSV format
- Importing CSV data in server-side Swift projects
- Educational projects demonstrating RFC 4180 compliant parsing
- Replacing unreliable CSV parsing code with a standards-based solution
- Handling CSV files with quoted fields and embedded line breaks correctly
Not Ideal For
- Processing very large CSV files that exceed available memory, as it's all in-memory parsing
- Applications requiring streaming or incremental parsing for real-time data processing
- CSV files with non-standard formats like tab-separated values or custom delimiters not covered by RFC 4180
Pros & Cons
Pros
Strictly adheres to the official CSV specification, ensuring reliable parsing of quoted fields, line breaks, and edge cases as confirmed in the README.
Offers straightforward methods like rows, headers, and keyedRows for easy data access, as shown in the TL;DR code example.
Automatically extracts headers and provides dictionary-like keyed rows, simplifying data manipulation with intuitive naming.
Implemented purely in Swift, reducing project complexity and avoiding reliance on third-party frameworks.
Cons
Processes all data in memory, making it unsuitable for very large files, as explicitly stated in the README.
Focuses only on parsing per RFC 4180, lacking features like streaming, custom delimiters, or CSV writing capabilities.
Can lead to high memory usage and slower performance with large datasets compared to streaming-based libraries.
