Update 2018-01-29

I had to shut down the Demo server because someone is using it to mine bitcoins. (by default, jupyter will allow anyone to create a terminal and there's no way to disable it easily.) If anyone is interested in setting it up locally, I'm glad to help.


Build Status

iSwift is the kernel IPython/Notebook implementation for Swift programming language.

It can:

  • Execute swift code on the Jupyter Notebook web editor, Jupyter console as well as Jupyter qtconsole.
  • Import Foundatation/Dispatch and other Buildin libraries.
  • Autocomplete swift code by pressing tab ↹.
  • Support encryption.
  • Support Linux/macOS





  • macOS/Linux
  • Swift 3.0
  • ZMQ  + Jupyter 5.0

macOS Installation

Clone this repo locally. And:

  1. Follow this script to install the libzmq on your machine.

  2. Build the project.

swift build
  1. Currently, in order to run swift kernel locally, you need to create a file named kernel.json. Put the following content to the file and replace the Path/to/iSwift with your local clone path.
 "argv": ["Path/to/iSwift/.build/debug/iSwift", "-f", "{connection_file}"],
 "display_name": "Swift",
 "language": "swift"
  1. Install Jupyter kernel: (replace the Folder/that/has/kernel/json with the path of the folder that contains the kernel.json file)
jupyter-kernelspec install Folder/that/has/kernel.json
  1. Run Jupyter Notebook (token needs to be empty):
jupyter notebook --NotebookApp.token=

Linux Installation

  1. Install Swift 3.0.
  2. Check if you have libzmq installed.
  3. Continue from step 2 in the section above.

Docker Installation

Simply clone this repo and run docker build -t iswift .. It will build the docker image.
