Apple introduced AppClips with a lot of documentation.
One of the options to invoke this AppClip is by scanning a QR code, here's a sample from Apple:
However, I can't find any info on how to create these kinds of codes.
Where can I find this information?
Creating App Clip Codes is now available through App Store Connect or using an App Clip Code Generator tool.
More information can be found here: https://developer.apple.com/documentation/app_clips/creating_app_clip_codes
The image in the question is not of a QR code but of an Apple proprietary equivalent that will probably be released later this year with the new iPhones.
As of September 15th, 2020, Apple says:
Tools for creating these new codes will be available later this year.
I developed an AppClip, first, I used a legacy QR code like this, it performs well:
NFC / QR code contain url as an input for your AppClip, then I handled it via NSUserActivityTypeBrowsingWeb
MyMainAppView()
.onContinueUserActivity(NSUserActivityTypeBrowsingWeb, perform: { userActivity in
ActivityHandler.handleUserActivity(userActivity, routerState: self.history ?? nil)
})
As of your example image, APPLE will release tools later this year to create these. NFC and QR codes you can create normally, as per my information since if you see WWDC video they are simple URL links embedded
