[Xcode16] Unable to install apps for development

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 <app> to <device>"
  • 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" }

I have also tested with Xcode16.1RC and it has the same issue. This issue completely blocks development, please let me know if there is something I can try to fix this.
