title: Show metadata of file with URL
body: <p>I am building a macOS application and am using NSOpenPanel to get access to the system file structure so I can get to any file and import it to the app I am making. I am able to get the URL of a file, and the string of said URL, but I was wondering if there was a simple way to extract metadata of the file at the URL and display it in a textfield?</p>
