# Screenshot Detector

A simple app that shows how to discover screenshots by leaving a persistent `NSMetadataQuery` running. It can be used to find all existing screenshots, or when a user takes a new screenshot. It relies on a certain spotlight attribute (`kMDItemIsScreenCapture`) that gets set on screenshot files.

It also uses bindings. Profusely.

# Screenshot

This is a screenshot of the screenshot detector, which is showing a screenshot of the screenshot detector showing a screenshot, which is showing a screenshot of the screenshot detector showing a screenshot, which is showing a screenshot of the screenshot detector showing a screenshot, which is showing a screenshot of the screenshot detector showing a screenshot. The universe will implode now.
