Monitor file system changes using Swift. Witness provides a wrapper around the File System Events API for OS X.

The recommended way to include Witness in your project is by using Carthage. Simply add this line to your Cartfile:

github "njdehoog/Witness" ~> 0.1 

If you're using Swift 4, point your Cartfile to the swift_4 branch.

github "njdehoog/Witness" "swift_4" 

Import the framework

import Witness

This will trigger an event when a file in the Desktop directory is created, deleted or modified.

iflet desktopPath =NSSearchPathForDirectoriesInDomains(.DesktopDirectory,.UserDomainMask,true).first {self.witness =Witness(paths:[desktopPath], flags:.FileEvents, latency:0.3){ events inprint("file system events received: \(events)")}}
