CSV.swift is a powerful swift library for parsing CSV files that supports reading as [String]
, [String: String]
and Decodable
, without sacrificing performance.
CSV.swift also supports the new async/await
functionality of swift 5.5.
There are already a few CSV parsers for Swift, but I was not able to find one that had support for high-speed parsing, while still offering convenience features, such as parsing Decodables.
[Coming Soon]
CSV.Swift is compatible with Swift Package Manager. Simply add it to your project's Package.swift
.
dependencies: [
.package(url: "https://github.com/benkoska/csv.swift.git", from: "0.1.0")
],
targets: [
.target(
name: "Project",
dependencies: [
.product(name: "CSV", package: "csv")
]
)
]
After the installation you can import CSV
in your .swift
files.
import CSV

let string = "joe,doe,28"
let parser = try CSVParser(url: url, header: ["firstName", "lastName", "age"])
Get next as array
parser.next() // => Optional<["joe", "doe", "28"]>
Get next as dictionary
try parser.nextAsDict() // => Optional<["firstName": "joe", "lastName": "doe", "age": "28"]>
Decode next from Decodable
struct Person: Decodable {
let firstName: String
let lastName: String
let age: Int
}
try parser.next(as: Person.self) // => Optional<Person(firstName: "joe", lastName: "doe", age: 28)>
let parser = try CSVParser(url: url)
let parser = try CSVParser(url: url, delimiter: "|")
let parser = try CSVParser(url: url, delimiter: "|", quotationMark: "'")
let parser = try CSVParser(url: url, delimiter: "|", quotationMark: "'", hasHeader: true)
let parser = try CSVParser(url: url, delimiter: "|", quotationMark: "'", header: ["firstName", "lastName", "age"])
let string = "joe,doe,28\njane,doe,21"
let string2 = "joe|doe|28\njane|doe|21"
let string3 = "firstName|lastName|age\njoe|doe|28\njane|doe|21"
let parser = try CSVParser(string: string)
let parser = try CSVParser(string: string2, delimiter: "|")
let parser = try CSVParser(string: string3, delimiter: "|", quotationMark: "'")
let parser = try CSVParser(string: string3, delimiter: "|", quotationMark: "'", hasHeader: true)
let parser = try CSVParser(string: string2, delimiter: "|", quotationMark: "'", header: ["firstName", "lastName", "age"])
let parser = try CSVParser(data: data)
let parser = try CSVParser(data: data, delimiter: "|")
let parser = try CSVParser(data: data, delimiter: "|", quotationMark: "'")
let parser = try CSVParser(data: data, delimiter: "|", quotationMark: "'", hasHeader: true)
let parser = try CSVParser(data: data, delimiter: "|", quotationMark: "'", header: ["firstName", "lastName", "age"])
Until Swift.CSV
reaches version 1.0.0 the API is subject to breaking changes between minor version jumps.
The being said, I will try to minimize breaking changes to the public API.
