How do I find the UDID for my iPhone 6?

Setting up/registering my device for testing requires a UDID [Certificates | Devices |iPhone]. According to various Apple support pages, that is supposed to be on the Settings/About screen, but with 10.2 that's no longer the case.

Got it; just connect the device and go to Xcode 'Window | Devices'

Also via iTunes - select the device, then click on the serial number...first click is UDID (then ECID then Model Identifier) - right click and 'copy'.

You have to have a DATA cable that still works, connecting your iPhone to your computer ... then it can be detected in Xcode and iTunes ...
