Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding Stringify as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/NovichenkoAnton/Stringify.git", .upToNextMajor(from: "1.0.0"))



  1. Apply masks for the string in specific range. The range compatible with CountableRange, ClosedRange, PartialRangeFrom, PartialRangeThrough, PartialRangeUpTo.
let cardNumber = "1234567890123456"
let masked = cardNumber.maskSubstring(in: 6...13, with: "*")
print(masked!) //"123456********56"
  1. Convert String to Double. If String is not compatible with Double the function will return 0.00.
let amount = "100,12"
print(amount.toDouble()) //100.12

let anotherAmount = "1 200,10"
print(anotherAmount.toDouble()) //1200.1 
  1. You can apply specific format for strings
let sum = "1234"
let formattedSum = sum.st.applyFormat(.sum)
print(formattedSum) //"1 234,00"

Supported formats

enum Format {
  case sum(minFractionDigits: Int = 2, maxFractionDigits: Int = 2)
  case creditCard
  case iban
  case custom(formatter: NumberFormatter)
  1. Validate a number of credit card by Luhn algorithm.

  2. Validate the string with specific pattern

"https://www.google.com".validate(with: .website) //true
  1. Simple date formatter (from one format to another)
let dateTime = "2019-11-22 13:33"

let resultTime = dateTime.st.convertDate(from: "yyyy-MM-dd HH:mm", to: "h:mm") //"1:33"
  1. Get query items from String that corresponds to URL type. Works for URLs with cyrillic domain names.
let stringURL = "https://test.com?foo=1&bar=abc"

let queryItems = stringURL.queryItems()! //["foo": "1", "bar": "abc"]


  1. You can append two attributed strings with +
let part1 = "123"
let part2 = "456"

myLabel.attributedText = part1.attributed + part2.attributed
  1. Apply attributes for mutable string
let string = "Some text"

label.attributedText = string.attributed.applyAttributes([
  .color(color: .red),
  .font(font: .systemFont(ofSize: 32, weight: .bold)),
  .crossed(width: 1, color: .black),
  .underline(style: .single, color: .blue)


  1. Apply styles for string
let sum = "1000,22"

label.attributedText = sum.attributed.applyStyle(.sum(integerAttrs: [
  .color(color: UIColor.red),
  .font(font: UIFont.systemFont(ofSize: 32, weight: .bold)),
  .underline(style: .double, color: .black)
], fractionAttrs: [
  .color(color: UIColor.green),
  .font(font: UIFont.systemFont(ofSize: 24, weight: .medium)),
], currencyMark: "$"))
