Getting Started

After adding KeyboardKit to your project, make your extension inherit KeyboardInputViewController instead of UIInputViewController. It provides you with many tools that helps you build custom keyboard extension.

KeyboardKit supports both UIKit and SwiftUI, so you can pick the option that suits your needs best. SwiftUI support is currently kept in a separate library, but will be the main focus going forward.


Since version 2.7.0, KeyboardKit provides new tools that help you build SwiftUI-based keyboards. SwiftUI will be the main focus going forward, with the aim to improve SwiftUI support in version 3.x and move it to the main repo in 4.0. When this happens, KeyboardKit will target iOS 13 and up.

Due to a Swift toolchain bug, SwiftUI support must be kept in a separate library. Until the bug is fixed, you must add both KeyboardKit and KeyboardKitSwiftUI to your project, if you want to use KeyboardKit with SwiftUI.


KeyboardKit supports many different keyboard actions, like character inputs, emoji inputs, backspace, newline, space, image etc. You can even create your own, custom actions.

Keyboard Types

KeyboardKit supports many different keyboard types, like alphabetic, numeric, symbolic, emoji etc. You can even create your own, custom keyboard types.


KeyboardKit supports autocomplete and can present autocomplete suggestions to users as they type.

Haptic Feedback

KeyboardKit supports haptic feedback and can give users haptic feedback as they type.

Audio Feedback

KeyboardKit comes with many keyboard-specific extensions. Check out the demo apps and source code for examples and more information.

Views and components

KeyboardKit comes with many views and components that can be composed into custom UIKit and SwiftUI-based keyboards, e.g. button, rows, toolbars etc.

Demo Application

This repository contains two demo apps that demonstrate different keyboard types, like alphabetical (lower/uppercased and caps locked), numerical, symbols, emojis and images.

KeyboardKitDemoKeyboard uses UIKit while KeyboardKitDemoKeyboard_SwiftUI uses SwiftUI.

Note that audio feedback, haptic feedback and image actions require full access. Also, the image switcher is only shown on notch devices.

To run the demo app, open and run the KeyboardKit.xcodeproj project then enable the keyboards under system settings. Don't forget to enable full access.
