KeyboardKit helps you create custom keyboard extensions with Swift and SwiftUI.

KeyboardKit extends Apple's native APIs and provides you with a lot more functionality. It lets you create custom keyboards that mimic native iOS keyboards with just a few lines of code.

KeyboardKit supports custom input keys, layout, design, behavior, etc. You can even use completely custom views.

KeyboardKit can be installed with the Swift Package Manager:

https://github.com/KeyboardKit/KeyboardKit.git

KeyboardKit supports iOS, macOS, tvOS and watchOS, but some features are unavailable on some platforms.

KeyboardKit supports 63 keyboard-specific locales:

KeyboardKit Pro extends KeyboardKit with a lot of Pro features, such as localized keyboards and services, autocomplete, autocorrect, dictation, emoji keyboards and features, themes, etc.

After installing KeyboardKit, just import it and make your controller inherit KeyboardInputViewController instead of UIInputViewController:

import KeyboardKit

class KeyboardController: KeyboardInputViewController {}

This gives your controller access to new lifecycle functions, observable state, services, and much more.

You can then override viewWillSetupKeyboard() and call any of the setup functions to customize or replace the standard SystemKeyboard view:

class KeyboardViewController: KeyboardInputViewController {

    override func viewWillSetupKeyboard() {
        super.viewWillSetupKeyboard()
        setup { controller in
            SystemKeyboard(
                state: controller.state,
                services: controller.services,
                buttonContent: { $0.view },
                buttonView: { $0.view },
                emojiKeyboard: { $0.view },
                toolbar: { _ in MyCustomToolbar() }
            )
        }
    }
}

For more information, please see the getting started guide.

The online documentation has more information, articles, code examples, etc.

The repository has a demo app that shows how to display keyboard state, link to system settings, etc.

The demo app has two keyboards:

• Keyboard uses KeyboardKit and a customized SystemKeyboard.
• KeyboardPro uses KeyboardKit Pro and a customized SystemKeyboard with all locales, autocomplete, themes etc.

Just open and run the demo app in the Demo folder, then enable the keyboards under System Settings. Note that you need to enable full access for some features, like haptic feedback.

If you want to try KeyboardKit Pro without having to write any code or build the demo app from Xcode, there is a KeyboardKit app in the App Store, that lets you try out many pro features.

KeyboardKit is open-source and completely free, but you can sponsor this project on GitHub Sponsors, upgrade to KeyboardKit Pro or get in touch for freelance work, paid support etc.
