Hello, is there a possibility to use the actionClassifier in CreateML ro create a fitnessApp that can recognize the action AND GIVE CORRECTION feedbacks to the user by using the the recognized keypoints? Maybe 3 keypoints as an angle and give feedback? How can I access those joints in Xcode?

My device info is iPhone11 , ios14.6。After I download some app from AppStore, I see that the app size on the device setting storage space page is larger about 11 megabytes than the showed size on the AppStore detail page (while mostly the former is smaller about 5 megabytes than the latter)。So, I want to know , what reasons can result in this case happened ? How can my app enjoy this effect ？

It seems that iOS 15 has broken modal view controller 'drag to dismiss' under the following configuration: The presented modal contains a nested scroll view && the outer scroll view is horizontally scrollable In iOS 13 and 14, UIScrollViews would propagate scroll events correctly, and despite the nested scroll view complexity, downwards scroll events would bubble up to the modal drag-to-dismiss gesture when appropriate. In iOS 15, this seems to have broken (even for builds still targeting iOS 14). I'm presuming some of the internal logic for modal drag down changed to support the new sheet presentation APIs, and in doing so, nested scroll view support broke. I'm curious as to how many others are running into this issue, and if anyone has found a workaround. I've submitted a bug report, although given how late it is in the beta cycle I'm not hopeful we'll see a fix before the public release of iOS 15.0.

I just watched the "Customize and resize sheets in UIKit" session and would like to know if/when the functionality in that session will be exposed in SwiftUI. Also, can we have customizable detent sizing? Based on content ideal height? Thanks!
