-     Use a QLPreviewProvider to provide data-based previews.

-     To set up your extension as a data-based preview extension:
-
-     - Modify the extension's Info.plist by setting
-       <key>QLIsDataBasedPreview</key>
-       <true/>
-     
-     - Add the supported content types to QLSupportedContentTypes array in the extension's Info.plist.
-
-     - Change the NSExtensionPrincipalClass to this class.
-       e.g.
-       <key>NSExtensionPrincipalClass</key>
-       <string>$(PRODUCT_MODULE_NAME).PreviewProvider</string>
