If you have a small group of test devices, signing your apps with an Ad Hoc certificate is the most practical way to distribute your app. For Ad Hoc signing you need to make sure to pre-register all the devices that you want to run the app on with your unique device identifier (UDID). It requires you to register your devices in advance on the Apple Developer Portal.
In case you are not sure how to find and register your UDID we have got your back! Below you can find an instruction that will guide you through the registration process step by step.
Take your devices and let’s start.
Every iOS device has a Unique Device IDentifier or UDID assigned to it. Finding the UDID used to be simpler, nowadays you have to either:
Connect your device to Xcode, open the
Window > Devices and Simulators menu, find your device in the list. You can now see the UDID where it says "identifier"
On macOS Catalina you can see the UDID of a connected device in Finder
Connect your iOS device to your machine
click on your device.
From there, click on the "Serial Number" text to reveal the device's UDID.
If you don't want to connect the device physically to your computer, you can use our service which allows you to read the UDID on the device directly and you can send the identifier then to you via email. Updraft will guide you through the necessary steps.
Once you have your UDID, you need to enter it in the "Devices" tab of the
Certificates, IDs & Profiles section on the Apple Developer portal.
Sign in to http://developer.apple.com .
Click on "Certificates, Identifiers & Profiles" in the right sidebar (http://developer.apple.com/account/ressources/devices/list).
Click the plus icon (+) to add a new device
Click Register Device
Enter the device name and the collected UDID
Continue and then Register
Select Profiles on the left sidebar
Select the provisioning profile to which you want to add the new device and click on Edit.
Select the App ID for your app
In the list of all devices, select all or just the ones that you want to include in the provisioning profile
Click on Generate. After the Profile is generated you can download it
Import the downloaded profile to Xcode
Open Xcode and select your project in the left sidebar
Click on Build Settings
