What SF Symbols is for Icons, TranslateKit is for Text!
Eliminate localization overhead in your Swift apps with 1000+ pre-localized strings and semantic key generation. Make app localization simple, accurate, and delightful.
Access 1,000+ ready-to-use strings in ~40 Apple platform languages across four categories. Since these are pre-localized, they won't add entries to your String Catalog – just use them directly:
// Actions: Interactive UI elements
Button(TK.Action.save) { saveData() } // "Save" → "Sichern" (German)
// Labels: Non-interactive text
Label(TK.Label.notifications, systemImage: "bell") // "Notifications" → "Benachrichtigungen"
// Placeholders: Temporary text
TextField(TK.Label.firstName, text: $firstName, // "First Name" → "Vorname"
prompt: TK.Placeholder.firstNameExample) // "e.g. Jane" → "z.B. Erika"
// Messages: Full sentences
Text(TK.Message.anErrorOccurred) // "An Error Occurred" → "Ein Fehler ist aufgetreten"Discovering the right translations is effortless with autocompletion – type TK. to explore categories and fuzzy-match strings, with English previews and usage hints in the documentation popover:
The #tk macro eliminates the tedious work of manual key management by automatically generating semantic keys based on code context:
struct SettingsView: View {
let documentName: String
var body: some View {
// Generates key: SettingsView.Body.saveChanges
Button(#tk("Save Changes")) { handleSave() }
// Add context with 'c' parameter to help translators
Text(#tk("Save changes to \(documentName)?",
c: "e.g. 'Save changes to MyNumbers.csv'"))
}
}String Catalogs made it challenging to maintain best practices from the Strings-file era, where using semantic keys helped group related translations. The macro brings back this advantage while keeping String Catalogs' benefits - you get semantic keys without writing verbose String(localized:defaultValue:comment:) calls:
These semantic keys help group related translations and provide crucial context to translators and translation tools (like the TranslateKit Mac app), leading to more accurate translations while making your localization files easier to maintain.
For Swift packages, use #tkm instead of #tk to reference the correct String Catalog file:
- Add
defaultLocalizationto your manifest:
.target(
name: "MyModule",
defaultLocalization: "en"
)-
Add
Localizable.xcstringsto your module -
Use the
#tkmmacro:
Text(#tkm("Last seen %@", c: "Time when user was last active"))Contributions – especially additions and corrections – are welcome!
Please feel free to submit a Pull Request. You don't need to localize added entries to all languages yourself, just provide the one(s) you speak, we'll take care of the other languages using TranslateKit. But please keep the entries sorted alphabetically when adding new ones!
For bigger changes, please open an issue first to discuss what you would like to change.
