The TextBundle file format simplifies the exchange of plain text files like Markdown or Fountain between sandboxed applications on Mac and iOS devices. Sandboxing ensures data security by restricting app access to user-provided files, causing inconveniences like granting image file permissions when working with Markdown files. TextBundle solves this by bundling text and images into a single file, eliminating the need for additional permissions. Supporting apps like Bear, Craft, and Ulysses make it easy to work with TextBundles. Developers can use the TextBundle library from Shiny Frog for easy integration.
