Localization

LaunchSwift uses String(localized:)/localized Text with Xcode String Catalogs.

AppLanguage enum

Defined in LocalizationManager.swift:

enum AppLanguage: String, CaseIterable, Codable, Sendable {
    case en
    case es
    case fr
    case de
    case pt
    case ja
}

LocalizationManager API

struct LocalizationManager: Sendable {
    var preferredLanguage: AppLanguage
    func currentLocale() -> Locale
}

Implementation details:

• preferredLanguage is persisted in UserDefaults (preferredLanguage key)
• default language is .en
• currentLocale() returns Locale(identifier: preferredLanguage.rawValue)

App root locale injection

LaunchSwiftApp injects locale like this:

.environment(\.locale, localizationManager.currentLocale())

Current behavior notes

• LocalizationManager is a struct (not an @Observable class).
• There is no dedicated language picker screen in the current SettingsView.
• The localization foundation is present (language enum + persisted preference + locale injection), while in-app language switching UI is not yet implemented.

Supported languages in source

Current language codes in AppLanguage and the shipped string catalog:

• en
• es
• fr
• de
• pt
• ja

Adding a language

1. Add a new case to AppLanguage in LocalizationManager.swift
2. Add translations in ios/SwiftLaunch/Resources/Localizable.xcstrings
3. Ensure your app flow updates preferredLanguage where you expose language selection UI
