Streamline your localized strings

3:30 - Declaring a string

Button("Order")

3:44 - Declaring a string anywhere else

button.title = NSLocalizedString("Order", comment: "…")
button.title = String(localized: "Order")

4:20 - Declaring a string in a SwiftUI view 2

Text("Your order is ready.")
Button("Order") {
  // Action…
}

4:33 - Declare a string in SwiftUI view with verbatim

Text(verbatim: "Sample data")

4:54 - Button to place an order

// SwiftUI
Button("Order") { … }


// Swift
button.title = String(localized: "Order")

5:15 - Button to place an order with a variable

let count = 3


// SwiftUI
Button("Order \(count) Tickets") { … }


// Swift
button.title = String(localized: "Order \(count) Tickets")

5:36 - Button to place an order with a variable 2

let count = 3

// Supports user’s preferred numbers,
// pluralization, RTL variables isolation…
// Previously: .localizedStringWithFormat()
String(localized: "Order \(count) Tickets")

6:21 - Use 2 separate strings

// Recommended for all languages
String(localized: "Order Now")
String(localized: "Order Later")

6:57 - Button to place an order 2

// SwiftUI
Text("Order")


// Swift
String(localized: "Order")

7:09 - Button to place an order with comment

// SwiftUI
Text("Order", comment: "Button: confirms concert tickets booking”)


// Swift
String(localized: "Order", comment: "Button: confirms concert tickets booking")

7:36 - What makes a good comment

Text("Order", comment: "Button: confirms concert tickets booking")
Text("Order", comment: "Button: confirms concert tickets booking")
Text("\(ticketCount) Ordered", comment: "Order summary: total number of tickets ordered")

10:52 - Request server strings in the user's language

Bundle.preferredLocalizations(from: allServerLanguages).first

11:37 - Declare a string with a variable, customized table name, and a comment

Text("\(ticketCount) Ordered",
     tableName: "UserProfile",
     comment: "Profile subtitle: total number of tickets ordered")

13:49 - Using a framework

/* —-----------—------------—-—---- In TicketKit Framework —---------—------------—-—---- */

// TicketKit/OrderStatus.swift
public enum OrderStatus {
    case pending, processing, complete, canceled, invalid(Error)

    var displayName: String {
        switch self {
        case .complete: return String(localized: "Complete",
                                      bundle: Bundle(for: AnyClassInTicketKit.self),
                                      comment: "Standalone ticket status: order finalized")
          
/* —-----------—-----------—---—---       In Host App      —---------—------------—-—---- */

import TicketKit
Text(OrderStatus.complete.displayName)

17:43 - Import translated strings catalogs

xcodebuild -exportLocalizations -workspace VacationPlanet.xcworkspace -localizationPath ~/Documents
xcodebuild -importLocalizations -workspace VacationPlanet.xcworkspace -localizationPath ~/Documents/de.xcloc

18:28 - Localized attributed strings

AttributedString(localized: "Your order is **complete**!",
                 comment: "Ticket order confirmation title")

19:22 - Plural with stringsdict

String(localized: "Order \(ticketCount) Ticket(s)")

22:46 - Plural for strings without a number

if ticketCount == 1 {
    button.text = String(localized: "Order This Ticket")
} else if ticketCount == 2 { // If needed
    button.text = String(localized: "Order Both Tickets")
} else {
    button.text = String(localized: "Order All Tickets")
}

23:31 - Automatic grammar agreement

AttributedString(localized: "Order ^[\(ticketsCount) Ticket](inflect: true)")

25:45 - Format data in strings

["pop", "rock", "electronic"].formatted(.list(type: .or)) // pop, rock, or electronic

Text("Total: \(price, format: .currency(code: "USD"))", // Total: $9.41
     comment: "Order subtitle: total price of all tickets")
