Xcode 26 b4 stopped recognizing connected iPhone (MacOS 26)

Hello. I am a complete novice. I have a MacOS26 partition as well as a 15.5 one. I use 26 for dev. Today, after booting into 26, Xcode (both version 26 and 16.4) are failing to recognize the iPhone which i've been using as a test device. I have made no changes to the install, i've simply been using 15.5 for a couple days, and when i booted back into 26, it just wouldn't work.

Both Xcode 26 and 16.4 see the device when in MacOS 15.5.

I have tried the following:

  • restarting all devices
  • switching wireless network
  • no VPN on either phone or computer
  • reinstalling xCode
  • starting a new project
  • manually adding device (no connected devices found)
  • turning off and on developer mode on phone
  • restarting usbmuxd
  • different cables and ports

I don't know what else to try at this point. I'd rather not reinstall macos on the other partition if possible.

Thanks very much.

Did you try unpairing the phone in xcode's device/simulator window?

Thanks for the reply! Yes, but the device list is empty, so there's nothing to unpair. I tried adding one with the plus sign, but i get a "no connected devices found" popup window
