Xcode Crash on View Hierarchy debugger for mixed UIKit / SwiftUI app
For a large / older iOS app project, we have noticed the the view hierarchy debugger works fine for our UIKit screens, but runs into the following crasher whenever we try to launch the view hierarchy debugger on a UIHostingVC screen with SwiftUI content: Unable to capture the view hierarchy "AppName" encountered an unexpected error when processing the request for a view hierarchy snapshot. -- The operation couldn’t be completed. Log Title: Data source expression execution failure. Log Details: error evaluating expression “(BOOL)[[(Class)objc_getClass("DebugHierarchyTargetHub") sharedHub] performRequestInPlaceWithRequestInBase64:@"..."]”: error: Execution was interrupted, reason: EXC_BAD_ACCESS (code=2, address=0x16b23bff8). Has anyone successfully resolved the underlying issue in this crasher? Tried all the typical recommendations for a clean build, clear derived data, use the "Debug -> View Debugging" menu - all with no resolution. Reported using Feedback Assistant: FB18514200 Thanks

Metrics in XCode Organizer stuck with margins of error
Hello My team has noticed that starting around early-October 2023 all of our 90th and 50th percentile metrics in Organizer have been stuck with the "margin of error" detail, ranging from 10-20 percent. We've been consistently using Organizer for over a year and usually see the margin of error for only for a couple days after a new app update is published - but now appear to be stuck without any clear reasons why. We've also tried on different versions of xcode 15, tried using "View -> Reload Organizer"; all with no success. In general speak, our app: has about a million sessions a day has weekly releases does not have metric issues in our other 3rd party libraries Has something changed with the user opt-in for sharing data with developers? Has anyone else experienced this problem? Thanks
