A helper library to generate Csv in Csv2Img library.
- Define custom type that conforms to
CsvComposition.
import Foundation
import Csv2Img
public struct CsvCompositionExample: CsvComposition {
@CsvRows(column: "age")
public var ages: [String]
@CsvRows(column: "name")
public var names: [String]
public init() { }
}- Build
Csv
let composition: CsvCompositionExample = .init()
composition.ages.append(contentsOf: ["98", "99", "100"])
composition.names.append(contentsOf: ["Yamada", "Tanaka", "Sato"])
let csv = try! composition.build()or you can write different way like the below.
let yamada = Csv.Row(index: 0, values: ["98", "Yamada"])
let tanaka = Csv.Row(index: 1, values: ["99", "Tanaka"])
let sato = Csv.Row(index: 2, values: ["100", "Sato"])
let csv = try! CsvCompositionParser.parse(type: CsvCompositionExample.self, rows: [yamada, tanaka, sato,])| Result |
