The ibplugin file extension is associated with Interface Builder, Apple's tool for creating application user interfaces within Xcode.
The ibplugin file stores a plug-in that adds features to Interface Builder, such as additional design-time controls or related features.
It belongs to the Xcode development environment on Apple macOS and earlier versions of Mac OS X.
An ibplugin file is not normally opened as a standalone document. It is intended to be installed and loaded by a compatible version of Xcode and Interface Builder on macOS.
If the file is not recognized by the installed version of Xcode, it may be incompatible with that version. The plug-in can be viewed in Finder, but that does not run its Interface Builder features.
There is no standard conversion from an ibplugin file to another file format. It is a plug-in rather than an interface document or media file.
