How to find connected Device ID through iTunes Please note: Although my question is tangentially related to iOS development, it is not a development question; it is an iTunes user question!



iPhone 7+ here. I'm a developer playing around with iOS development for the first time, and am trying to deploy a toy/hobby iOS app (that I wrote via XCode) to my iPhone.

It looks like the first thing I need to do is figure out what my iPhone's Device ID is. Following the instructions for finding Device ID through iTunes, I launched iTunes and then connected my phone to it. However, whereas (according to that link) I should be seeing a screen that looks like this:



I only see a screen that contains three fields:


Capacity
Phone Number
Serial Number


But I don't see a Device ID or UDID field like the document says. Do iPhone's not have UDIDs? Is the Serial Number a useable substitute for UDID?
Click on your phone in the top-left corner to show phone details.



From here, you can choose Summary in the sidebar, then click on your serial to show the UDID.
