The .xcplugindata file extension is associated with Xcode, Apple's integrated development environment for macOS, formerly called Mac OS X. Xcode is used to develop applications for Mac computers and Apple mobile devices such as iPhone and iPad.
An .xcplugindata file stores supporting data for an Xcode plug-in. It is an auxiliary file belonging to the plug-in environment, not an Xcode project, source-code file, or standalone user document.
The file is intended for internal use by Xcode and the associated plug-in. It is not normally edited directly, and its contents may depend on the Xcode installation and plug-in that created it.
Xcode uses .xcplugindata files internally when working with the relevant plug-in. They are not normally opened or edited directly as ordinary documents.
If the file needs to be preserved, keep it with the plug-in or Xcode installation that created it.
There is no standard conversion for an .xcplugindata file. It is internal plug-in data rather than a document format designed for export.
Keep the file in its original plug-in environment.
