I am creating an app, and on the app, the user can select something like, let's say, their workplace, while creating their account. I want to append the workplace data to a model without the use of UI, so that I can display the workplace names that the user can choose from. How do I append the data to the model?

I wanted to create a provisioning profile for my project via my physical device, just as a test. However, my serial number and my capacity weren't identified. Could it be the cable?
