Ended up finding my problem. highlightCenter.highlights is not filled at the instantiation of highlightCenter, so I had to wait for the call to the delegate function.

Hi I installed the beta2 of iOS 16, and of Xcode 14. I'm finally able to see my app in Preferences > Messages > Shared with You. I toggled my app to YES. Shared with you is enabled in the conversation where I share universal links to my app The participant is a contact Both participants shared links And yet, I still get an empty array. Any idea why ?
