Get your UDID
The UDID (Unique Device Identifier) of an iOS device identifies it to Apple. You'll need to know the UDID of your development device in order to create a provisioning profile for it.
The UI for getting the UDID is a bit weird, so bear with us!
- Plug the device into your computer and open iTunes.
- Click the Serial Number until you see UDID.
- Right click and copy the UDID to extract from iTunes.
