Continuity Camera

Take a photo right to your Mac. Now you can use your iPhone to shoot or scan a nearby object or document and have it automatically appear on your Mac. Just choose Insert a Photo from the File menu. You can take a photo of something on your desk and instantly see it in your Pages document. Or scan a receipt, and a straightened version is immediately available in the Finder as a PDF. Continuity Camera works in the Finder, Mail, Messages, Notes, Pages, Keynote, and Numbers. It’s another way iPhone and Mac just click.

Answer 1

You need to use validRequestorForSendType:returnType:. More info in WWDC 2018 Session 209 around minute 36.

Answer 2

Thomas Zoechling wrote a little sample project that you can use to get continuity scanning working — it's pretty touchy and VERY inflexible. (Eg, there's no way to just directly invoke the Continuity Camera from your own code, you HAVE to use an NSMenu!)
