I'm seeing the same issue as the OP. I reset the cache in Diagnostics, and have registered an Advanced App Clip Experience, but it's not showing up. The frustrating thing is that the documentation implies that the default App Clip experience should work from a QR code, but it does not. So I'm hoping the advanced experience allows the App Clip card to show up in the Camera view when scanning a QR code…

Really nice job @noppefoxwolf!

It looks like Apple fixed the bug in Dictionary(uniqueKeysWithValues: ) at some point during this beta cycle. If you try now, the sample code should be working again!

Updated to add: the sample code is working, just unbelievably slowly. It turns out the culprit is the use of a [Substring: Int] dictionary in loadVocabulary. For some reason, constructing a dictionary with Substring keys takes many orders of magnitude longer than using String keys. Switching the implementation to [String: Int] solves the problem. When I have time, I'll file a bug for slow performance with Dictionaries using Substrings as keys.

I'm seeing a similar problem. The app just says "Searching" but never returns an answer. There's a log printed which could be a clue: 2022-07-03 08:42:45.859844-0500 FindingAnswers[32757:1495990] [default] failed to map shmem for window 0

It appears that CIRAWFilter (initialized with imageURL) does not respect its scaleFactor property at all. It always returns the full-size image. I'm going to file a bug today!
