My dev setup : Macos Sequoia - 15.0.1 (24A348) Xcode 16 - Version 16.0 (16A242d) iPhone15Pro - iOS Version 18.0.1 I recently upgraded to Sequoia which forced me to upgrade my Xcode version to 16. After this I am unable to deploy apps for testing on my iOS device. The build proceeds fine but then the installation hangs: Xcode says "Installing to " On the device, it just says Loading / Installing on the app icon and the install doesn't complete It remains stuck for a very long time with no progress and then I need to quit Xcode / manually hit 'Cancel download' on the device. Once in a way the installation goes through and the app runs fine. The same app used to install and run fine when deployed via Xcode15.3 (on macOS Sonoma). On one attempt I waited for 20mins or so and then app install failed with this message : "XPCErrorDescription" => <string: 0x1ef0097a0> { length = 22, contents = "Connection interrupted" } } Domain: IXRemoteErrorDomain Code: 6 User Info: { DVTErrorCreationDateKey = "2024-10-25 13:52:47 +0000"; IDERunOperationFailingWorker = IDEInstallCoreDeviceWorker; } -- Failed to install the app on the device.

This issue completely blocks development, please let me know if there is something I can try to fix this.
