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 XS. I tried adding the ECID and SEID but it didn't work.

I couldn’t find anything about the disappearance of the UDID on Google either.

Can anyone help me figure out how to register the iPhone XS in the Apple developer portal?

Solution 1

For the iPhone XS/XS Max and possibly other iPhones which do not show UUID in Itunes: - Open Xcode - Window -> Devices & Simulators -> Select your iPhone -> Use the "identifier" as shown below:

Solution 2

• 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.

Solution 3

You can compile the UDID from the ECID that is shown by iTunes with the following formula (for XS and XS Max)

0000CHIP-00ECID

The CHIP version in the XS/XS Max case is 8020 (source for it)

So if you want to compute the UDID for an XS/XS Max (and I believe the XR has the same chip), then you'll need to replace the ECID with your own in:

00008020-00ECID

To find the ECID, connect the iPhone to iTunes and click the serial number, the ECID will show up.

Edit: For the XR the formula is: 00008020-000ECID, because the ECID has one less character

Solution 4

The best way to get the UDID for the XS is(if you are a dev that is)

1. Connect your device to you mac
2. Open Xcode
3. Open Window->Devices and Simulators
4. Select your device
5. You will see identifier in a similar screen like the one below

Solution 5

Open Xcode -> Window -> Devices & Simulators -> Select your iPhone -> Identifier

Copy the value for Identifier. This is the UDID

It is not showing UDID I have checked it.

When you connect the device to your computer and try and build and run via Xcode, it will offer to add the device to the developer portal for you. If users are installing via TestFlight it will also happen automatically. Why do you need to do it manually?

Using terminal to find udid for new iPhones and iPads : stackoverflow.com/a/52997294/342794

[lal]

Terminal is useful alternative when team members (designers, testers, etc) don't have XCode installed. Or need to access UDIDs for devices remotely. stackoverflow.com/a/52997294/342794

It keeps complaining that this is not a valid UDID :(

[Paulw11]

Can you add the device through Xcode? I know iPhone XS serial number formats have changed, but i would have thought that the developer portal was ready for the change. I don't have an XS to test on.

[archonic]

This approach works, it's just missing a dash after the 8th character for the new UDID format.

[lal]

Adding a '-' is important. Just added a screenshot to the answer.

[Ashley Mills]

This is identical to @Paulw11's answer

[Ashley Mills]

This is clearly the best answer - no need to leave Xcode!

[jhub1]

This didn't work for me. So it turns out that the UDID is CORRECT...but for some reason UDID needs to be lower case!!! After I lower cased everything, it was then accepted. @Mehul

[jhub1]

@AshleyMills it is NOT Paul's answer. I followed his answer and it didn't work. That's why I copy pasted his answer and added one additional but critical step.

[Mehul]

@jhub1, Ok l will check and let you know soon. Thanks for your response.

[fishinear]

They did not need to be lower case for me.

[fishinear]

They did not need to be lower case for me, but the dash in the right place (after the first 8 digits) is important.

[fishinear]

But a need for your testers to install XCode

[Durga Sriram]

The above approach works. On the right top window, "USB 3.0 Bus" is selected by default but the selection should be "iPhone". Then only you will get the correct serial number. Copy and paste the value. You then need to add a – after the 8th digit. For Ex: if you got a serial number as "98gfhgd67f1a06b4f60156f1949fbytrd205c1f0", after adding - it should like this: "98gfhgd6-7f1a06b4f60156f1949fbytrd205c1f0".

Also complicates things when you have a remote device farm. stackoverflow.com/a/52997294/342794

@AshleyMills developer portal says its not valid. Any idea ?

Why is this -1 ? I use it for long time with pleasure. I can suggest this page.
