Apple Translation

APPLE ON-DEVICE TRANSLATION (Translation framework): FRAMEWORK: import Translation (iOS 17.4+, on-device, NO internet required, NO API key)

KEY DISTINCTION: Translation is for translating USER CONTENT on demand (e.g. translating a message from French to English). It is NOT for app localization (.strings files). Do not confuse the two.

MODIFIER APPROACH (simplest — shows system translation sheet): @State private var showTranslation = false Text(userContent) .translationPresentation(isPresented: $showTranslation, text: userContent) Button("Translate") { showTranslation = true }

PROGRAMMATIC TRANSLATION (TranslationSession): @State private var translatedText = ""

func translateText(_ input: String) async { let config = TranslationSession.Configuration(source: .init(identifier: "fr"), target: .init(identifier: "en")) let session = TranslationSession(configuration: config) do { let response = try await session.translate(input) translatedText = response.targetText } catch { // Handle: language pair not supported on device, model not downloaded } }

// Call with .task or Button: .task { await translateText(originalText) }

SUPPORTED LANGUAGES: Check Translation.supportedLanguages for the device's available language pairs. AVAILABILITY: Some language pairs require a model download on first use. NO ENTITLEMENTS NEEDED: Translation framework requires no special entitlements or Info.plist keys.
