About KXApp

iOS development in VS Code

KXApp is a lightweight iOS IDE built on VS Code, installed as a free VS Code extension. Swift, SwiftUI and Objective-C code completion, one-key builds, running and debugging on iPhone and the simulator, unit tests, and visual editors for Info.plist, app icons, localization and project settings. Your Xcode project stays as it is, so you can switch back to Xcode at any time.

The product

What KXApp does

Writing code, building, debugging on a device, running tests and changing project settings: the everyday work of iOS development, all in VS Code.

Swift code completion

Completion, go to definition, hover docs and live errors for Swift, SwiftUI, Objective-C and C++, including third-party libraries and Swift packages.

Code completion →

One-key builds

Switch scheme, configuration and run device from the status bar. Cmd+B builds, and a click on an error takes you to the line.

Build and run →

Debug on iPhone and simulators

Cmd+R installs and launches your app on an iPhone or simulator, with breakpoints, variables, call stack and console in VS Code.

Debugging →

Unit tests

Run XCTest and Swift Testing cases from the Test Explorer with a click; failures are marked on the line.

Unit tests →

Visual editors

Info.plist, entitlements, assets, app icons and localized strings all get a visual editor, so you never hand-edit XML.

Visual editors →

Project settings

Edit signing, version numbers and build settings visually. Open the project in Xcode afterwards and everything looks the same.

Project settings →

Why

Write code in VS Code.
Stop switching back and forth.

Plenty of iOS developers already write code and use AI assistants in VS Code, yet still switch back to Xcode to build, debug or change a build setting.

KXApp brings those steps into VS Code. No migration, and the results match Xcode: from writing code to debugging on an iPhone, one editor is enough.

KXApp is made by a team focused on iOS developer tools, and the extension is what we build for iOS development in VS Code.

What we stand for

An extension you can install without a second thought

  1. 01

    Same results as Xcode

    Building, signing and installing are done by the Xcode on your Mac, so if your project runs in Xcode, it runs in VS Code, and you can switch at any time.

  2. 02

    No migration

    Open your existing Xcode project and start. Nothing is converted or generated, and settings you change look exactly the same in Xcode.

  3. 03

    Free, no account

    Every feature is free. There's nothing to sign up for, and the extension doesn't upload your code.

  4. 04

    Issues in the open

    Bugs and suggestions are discussed publicly on GitHub, so you can always see where things stand.
