I installed Xcode 16.0 beta 2 in June, and today I needed to run a project that requires a higher version of Xcode, so I upgraded to other versions. I found that no matter which version I upgraded to, it would crash. However, at the same time, when I moved my Xcode 16.0 beta 2 version back from the trash, I was still able to open that version, while I couldn't open any other higher versions. Could this be related to the need for my Mac system to be upgraded?

macOS Sequoia Developer Beta I have tried everything, whether it's downloading the historical beta version from the website you provided or downloading version 16.2 from the AppStore.

I’m sorry for seeing your reply now. I hope to achieve a higher frame rate for object tracking. Even if it's just image tracking or any form of object tracking, I want the tracking rate to be able to identify hands. Perhaps using the term frame rate is not appropriate; currently, achieving 30Hz for object tracking is quite good, but there is a significant "delay"! We hope to have image tracking or other tracking methods that can reduce the sense of delay.

Alright, thank you. Regarding the reference object tracking time, I have received your answer. Additionally, I have used the enterprise APIs. What I want to say is that 30Hz allows me to track very smoothly, but there is a significant delay. It would be great if the delay could be as small as that of hand tracking.
