Ever since updating both my iPhone and iPad to iOS 18.1 beta 7, they simply won't connect to Xcode 16.1 beta 3.
When connecting via cable, Xcode gets stuck on preparing for 5 to 10 mins and then outputs the below error:
The developer disk image could not be mounted on this device.

Any solution for this issue?
Could you kindly try again and let us know the result? There were some transient service issues yesterday for many Apple Developer systems, and so that is a possible reason for this.
If you still get this message after trying again, you should also confirm that you have unimpeded network access, in case something like a network filter in a corporate environment is a part of your overall configuration, or just general internet connectivity issues on your end.
