Multiple third-party macOS apps now have a feature to edit photos, and the UI looks exactly the same as in Preview. How do we implement this functionality? Has a new framework been released?

Including links to screenshots for comparison. Some buttons are not included in the third-party app, but the UI and the behaviour is exactly the same in both apps.

Shotty (3rd party app) image editing controls

Apple Preview image editing controls

Your help would be greatly appreciated, a link to Apple documentation would already be helpful.

  • Looks like what you see is an [action extension](https://developer.apple.com/macos/human-interface-guidelines/extensions/action-extensions/) for images. If you add an `NSTextView` to your app with `importsGraphics` and `allowsImageEditing` set to `true`, you have a host app that supports those extensions. Just like TextEdit or Mail. But I am not sure how to support the extensions without an `NSTextView`. An `NSImageView` or `IKImageView` seems not to support it out of the box, but I could be wrong. – Daniel Apr 03 '18 at 10:00
  • The above workaround also works with `NSTextField`. – Daniel Apr 03 '18 at 10:07
