App Utilities
Powerful app models and templates
KeyboardKit provides main app utilities to let you build a great main app for your custom keyboard.
With its full screen estate and unlimited capabilites, the main app is a perfect place to onboard your users, provide keyboard settings, and to perform certain operations like dictation.
Keyboard App
KeyboardKit has a KeyboardApp
struct that is also a namespace for app-related types and views. You can create an app-specific KeyboardApp
value to define your appβs licenseKey
, appGroupId
, etc.
extension KeyboardApp {
static var keyboardKitDemo: KeyboardApp {
.init(
name: "KeyboardKit",
licenseKey: "your-key-here", // Sets up KeyboardKit Pro!
appGroupId: "group.com.keyboardkit.demo", // Sets up App Group data sync
locales: .keyboardKitSupported, // Sets up the enabled locales
autocomplete: .init( // Sets up custom autocomplete
nextWordPredictionRequest: .claude(...) // Sets up AI-based prediction
),
deepLinks: .init(app: "kkdemo://", ...) // Defines how to open the app
)
}
}
You can then use the value to set up your main app and keyboard extension to use the same config.
π KeyboardKit Pro
KeyboardKit Pro unlocks a HomeScreen
template that can be used as the main app root view, as well as a SettingsScreen
, LocaleScreen
, and ThemeScreen
, etc.:




These screens can be used independently as well, in case you have a custom home screen, and can be customized and localized to great extent.
