App Utilities

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 app’s 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.

👑 KeyboardKit Pro

KeyboardKit Pro unlocks a HomeScreen template that can be used as the main app root view, as well as a Keyboard.SettingsScreen, Keyboard.LocaleSettingsScreen, etc.:

Most features have their own settings screens that can be used in the main app and the keyboard:

These screens can be customized and localized to great extent, using convenient view modifiers.
