Observe user screen shot event and image in macOS.
pod 'Screeen'

observer.delegate = self
observer.start()func screenShotObserver(_ observer: ScreenShotObserver, addedItem item: NSMetadataItem) {

}Change observing status
observer.isEnabled = false // Stop observing
observer.isEnabled = true // Restart observingSecurity features have been enhanced since mac10.15 Catalina, and screenshot monitoring must be granted permission. The monitoring target can be specified for each directory, and the desktop directory is specified by default.
When call start() for the first time, a permission alert will be displayed and monitoring will start when allow it.
let observer = ScreenShotObserver()
observer.start()
let desktopPath = NSSearchPathForDirectoriesInDomains(.desktopDirectory, .userDomainMask, true).first
let picturePath = NSSearchPathForDirectoriesInDomains(.picturesDirectory, .userDomainMask, true).first
let directoryPaths = [desktopPath, picturePath].compactMap { $0 }
let observer = ScreenShotObserver(searchDirectoryPaths: directoryPaths)
observer.start()
let observer: ScreenShotObserver
if #available(macOS 10.15, *) {
observer = ScreenShotObserver()
} else {
observer = ScreenShotObserver(searchDirectoryPaths: [])
}
observer.start()
In order to monitor screen shots in a Sandbox enabled application, the user must manually select the directory to be monitored.
