CSV.swift

CSV reading library written in Swift.

Usage

From CSV string

import CSV

for row in try! CSV(string: "1,foo\n2,bar") {
    print("\(row)")
    // => ["1", "foo"]
    // => ["2", "bar"]
}

From file path

import Foundation
import CSV

let stream = InputStream(fileAtPath: "/path/to/file.csv")!
for row in try! CSV(stream: stream) {
    print("\(row)")
}

Getting the header row

import CSV

let csv = try! CSV(
    string: "id,name\n1,foo\n2,bar",
    hasHeaderRow: true) // default: false

let headerRow = csv.headerRow!
print("\(headerRow)") // => ["id", "name"]

for row in csv {
    print("\(row)")
    // => ["1", "foo"]
    // => ["2", "bar"]
}

Get the field value using subscript

import CSV

var csv = try! CSV(
    string: "id,name\n1,foo",
    hasHeaderRow: true) // It must be true.

while let _ = csv.next() {
    print("\(csv["id"]!)")   // => "1"
    print("\(csv["name"]!)") // => "foo"
}

Provide the character encoding

If you use a file path, you can provide the character encoding to initializer.

import Foundation
import CSV

let csv = try! CSV(
    stream: InputStream(fileAtPath: "/path/to/file.csv")!,
    codecType: UTF16.self,
    endian: .big)
