The Power of Live-Coding

truly Native Applications

for iOS, tvOS, macOS

What makes CodeFlow different?

Develop Native Applications Live

Innovation is often based on very simple ideas. The simple idea behind CodeFlow is that live feedback can make app development better.

CodeFlow enables you to see, immediately in the target application, changes you make in the app's source code or assets. You don't have to rebuild and restart the app; you don't waste your time waiting. And app development becomes more productive, creative, and fun.

Main features

Live Application Update

  • Target App is updated while running.
  • No app relaunch; the app's current state is preserved!
  • Live update everything: code, storyboards, image assets…
  • Wireless live app update on a device or in the simulator.

True Native Apps

  • Live code your app with the entire native OS SDK
  • iOS, tvOS and macOS SDKs supported.
  • Live update of native app resources: storyboards, SceneKit models…
  • No web view; no proprietary UI components.

Perfect Fit with Xcode

  • A CodeFlow project extends an Xcode project.
  • Both projects are automatically kept in sync.
  • Freely mix compiled Swift / ObjC code and dynamic code in your app.
  • Benefit from Xcode's specialized editors for live update: storyboards…

What can you do with CodeFlow?

CodeFlow is very flexible and you can use it in many different ways. Here are just a few examples.

Application Prototyping

  • Mockup entire applications or specific UX concepts.
  • Quickly iterate in code / storyboards / assets.
  • The prototype is a true functional native application.
  • Interactively improve the app prototype with the client or marketing team.
  • Use the prototype as the starting point for the real app.

Dynamic Storyboard Design & Debug

  • Easily add dynamic storyboard updates to existing apps.
  • Add, test and adjust layout constraints interactively.
  • Quickly fix layout issues in table views, stack views, collection views…
  • State is preserved: you stay in the current view controller when the storyboard is updated.

Multi-Screen Design

  • Make your app look good on all screen sizes
  • Live-update your app on multiple devices simultaneously and check how it looks on all screen sizes.
  • Become the master of size-classes.

Learn and Explore

  • Explore new APIs.
  • Try, fix, revert, improve at will.
  • Make self-training fun again.
  • Imagine, experiment, and unleash your creativity.
  • Enjoy the power of unlimited playgrounds.

Simple App Creation

  • Create entire apps in interactive mode,
  • or develop very specific parts of your app using live coding.
  • Ship the app with the dynamic code inside,
  • or remove the dynamic code before shipping, and push a traditional app to the store.
