I decided to go back and completely reinstall again. I wiped my new MacBook Pro back to just the Mac OS 15.2 and then used my time machine backup to restore my data and apps from my old MacBook Pro. When I completed this procedure again now Xcode is fully functional and communicating with my iPhone, both via USB and Wifi. At this point, I do not need any further assistance. Thanks for your response and I am glad to be able to move forward.
