i18n for Swift.

"order_view_title" = "Order"
"order_view_button" = "Order (price: %@)"
==========================

// "Order"
titleLabel.text = NSLocalizedString("order_view_title", comment: "")
// "Order (price: USD100.00)"
let price = "$100.00"
let buttonTitle = String(format: NSLocalizedString("order_view_button", comment: ""), arguments: price)
orderButton.setTitle(buttonTitle, for: .normal)


⬇️⬇️⬇️

// "Order"
titleLabel.text = i18n.t(.orderViewTitle)
// "Order (price: USD100.00)"
orderButton.setTitle(i18n.t(.orderViewButton, args: i18n.currencyISO(100)), for: .normal)

Features

• Swifty handling
• Localization
  • Safety,
  • Static typing
  • Change language without switching system language setting.
• Currency (convert number into currency using locale)
• Tested perfectly.

TODO

• Number
• Date
• Pluralization

Requirements

• Swift 3.x
• Xcode 8.x
• iOS 9.0 or later

Usage

Localization

• Create Localizable.strings

"hello_world" = "Hello, world!";
"total_count" = "Total: %d";

Add Localizable.strings in your project and define keys and values.

• Define LocalizedString

extension i18n.LocalizedString {
    static let helloWorld: i18n.LocalizedString = "hello_world"
    static let totalCount: i18n.LocalizedString = "total_count"
    // or
    static let helloWorld = i18n.LocalizedString(rawValue: "hello_world")
}

Add LocalizedString's static variable as extension of i18n.LocalizedString.
It's similar to Notification.Name. ❤️

extension Notification.Name {
    static let fooDidUpdate = Notification.Name(rawValue: "FooDidUpdate")
}

• localize with i18n

let message = i18n.t(.helloWorld)
print(message) // "Hello, world!

// localize and embed paramter(s)
let total = i18n.t(.totalCount, args: 100)
print(total) // "Total: 100"

Tips Add args: label and parameter(s) if you can embed arguments in localized string.

Language

i18nSwift equips function of changing the language in appllication.
If you change the language, result of localization will change.

// en
"greeting" = "Hello!";
// fr
"greeting" = "Bonjour!";

// system language is "en"
print(i18n.t(.greeting)) // "Hello!"

// Change language to "fr"
i18n.Language.current = "fr"
print(i18n.t(.greeting)) // "Bonjour!"

// ===================
// Reboot application!!
// ===================

// `Language.current` is being stored.
print(i18n.t(.greeting)) // "Bonjour!"

// Reset to system language
i18n.Language.reset()

// change temporary in localization
print(i18n.t(.greeting, "fr")) // "Bonjour!"

Tips : i18n.Language.current is saved in UserDefaults using i18n.Language.Constant.currentLanguageKey

Currency

i18nSwift converts number into localized currency.

// default is `Locale.current`

print(i18n.currency(100)) // $100.00
print(i18n.currency(100, Locale(identifier: "ja_JP"))) // ¥100
print(i18n.currency(100, fractionDigits: (4, 4))) // $100.0000
print(i18n.currencyISO(100)) // USD100.00
