Plugin Inspector

The Plugin Inspector is used to select and manage target platforms for the plugins in your project. Simply select a plugin file to view its Inspector.

Under Select platforms for plugin, choose which platforms will use the plugin by checking the appropriate boxes. If you select Any Platform, the plugin will apply to all platforms, including the Unity editor.

Once you have selected the platforms, you can choose additional options such as CPU type and specific OS from the separate Platform Settings section below. This contains a tab for each platform selected by the checkboxes. Most platforms have no settings, or just a few (such as CPU and OS selection).

The current list of file extensions that are treated as plugins and display the Plugin Inspector in the Unity Editor is found in PluginImporter::CanLoadPathNameFile(). The following file extensions identify files that are treated as plugins:

  • .dll
  • .winmd
  • .so

  • .c
  • .h
  • .jslib
  • .jspre
  • .bc
  • .a
  • .m
  • .mm
  • .swift
  • .xib

Certain folders are treated as a single bundle plugin. No additional plugins are detected within such folders. The following extensions identify folders that are treated as bundle plugins:

  • .framework
  • .bundle
