Registering Testing Devices
All iPhone/iPads you want to install and test your iOS app on prior to publishing need to be registered to your Apple Developer account. The UDID (Unique Device Identifier) for each device is added to the provisioning profile for your app which permits the app to be installed on those specified devices outside of the App Store.
To register a test device enter the UDID and a device name. Once registered, the device will be included in the provisioning profile used during the build allowing the IPA to be installed and launched on that device.
Rebuild your iOS app after adding new test devices
After adding new test devices your app will need to be rebuilt to use the updated provisioning profile that includes those new devices.
