Welcome to the April 2019 release of Visual Studio Code. During April, we were busy with the Preview release of the Remote Development extensions. These extensions let you work with VS Code over SSH on a remote machine or VM, in Windows Subsystem for Linux (WSL), or inside a Docker container. 

The IBM Swift Sandbox is an interactive website that lets you write Swift code and execute it in a server environment – on top of Linux! Each sandbox runs on IBM Cloud in a Docker container. In addition, both the latest versions of Swift and its standard library are available for you to use.
