KeyboardKit is a Swift SDK that lets you create fully customizable keyboards in a few lines of code, using SwiftUI.

KeyboardKit extends Apple's native APIs and provides you with a lot more functionality. It lets you mimic the native iOS keyboard and tweak its style and behavior, or create completely custom keyboards.

Custom iOS keyboard extensions can be used with all other apps that support text input. It's the only way for your product, brand or technology to directly interact with other apps on iOS. Don't miss out!

KeyboardKit Pro extends KeyboardKit with pro features like fully localized keyboards & services, autocomplete, an emoji keyboard, AI supporting capabilities, themes, dictation, and much more.

KeyboardKit Pro is closed source and requires a commercial license.

Licenses can be purchased from the website or from Gumroad.

KeyboardKit Pro can be installed with the Swift Package Manager:

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

Important! Unlike KeyboardKit, KeyboardKit Pro is a binary target and must only be added to the app target. If you add it to any other target, it may crash at runtime.

After installing KeyboardKit Pro, just make your KeyboardViewController inherit KeyboardInputViewController instead of UIInputViewController:

import KeyboardKitPro

class KeyboardController: KeyboardInputViewController {}

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

If you just want to use the default SystemKeyboard view, which mimics a native iOS keyboard, you only have to register your license key on launch:

func viewDidLoad() {
    super.viewDidLoad()
    let license = try? setupPro(
        withLicenseKey: "your-key",
        locales: [...], // Define which locales to use 
    ) { license in
        // Make any license-based configurations here 
    }
}

To replace or customize the default SystemKeyboard, just override viewWillSetupKeyboard and call setupPro with a view builder:

class KeyboardViewController: KeyboardInputViewController {

    override func viewWillSetupKeyboard() {
        super.viewWillSetupKeyboard()
        try? setupPro(
            withLicenseKey: "your-key",
            locales: [...], // Define which locales to use
            licenseConfiguration: { license in
                // Make any configurations and service adjustments here
            },
            view: { [weak self] controller in // <-- Use [weak self] or [unowned self] if you need self here.  
                SystemKeyboard(
                    state: controller.state,
                    services: controller.services,
                    buttonContent: { $0.view },
                    buttonView: { $0.view },
                    emojiKeyboard: { $0.view },
                    toolbar: { _ in MyCustomToolbar() }
                )
            }
        )
    }
}

Every article in the documentation describes in detail what KeyboardKit Pro unlocks for that part of the SDK.

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

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

The demo app has two demo keyboards:

• Keyboard uses KeyboardKit and a customized SystemKeyboard.
• KeyboardPro uses KeyboardKit Pro and enables 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 to work.

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.
