Xcode 15 and iOS 17.0.2 causing debugging issues when running from Xcode using a cable. When I updated to the new Xcode 15 and device to iOS version to 17.0.2, it is taking a long delay of 1 to 3 minutes to launch the app in the real device. It is also really slow after launching. Every step over or into take almost a minute. I can see the below warning in console "warning: libobjc.A.dylib is being read from process memory. This indicates that LLDB could not find the on-disk shared cache for this device. This will likely reduce debugging performance." I tried with the fix of executing the following command to clear the Device support files rm -r ~/Library/Developer/Xcode/iOS\ DeviceSupport. But even after I am facing the same issue.

Please do the needful to fix this issue.

After deleting all files in ~/Library/DeveloperXcode/DerivedData/ everything works as expected for me.

Same here for Xcode 15.2.

It's like being a web developer we've got to put print statements everywhere because breakpoints are now completely useless with devices.
