iPhone XS doesn't have UDID

Question

I want to add an iPhone XS UDID in the Apple developer portal but I am unable to find the UDID in iTunes and without adding the UDID I am unable to run my app on the iPhone

Answer 1

• Go to "->About This Mac".
• Click on "System Report" and select "USB".
• Find your phone and the "Serial Number" field is what you are after.
• Copy this value and paste it into the developer portal when you register a new device; you will need to insert a - after the 8th digit.

You can also get the "identifier" from the Xcode "devices" window or have Xcode update the portal directly.
