Hello @jawshoeadan, thank you very much for creating a Pull Request! Here is a small checklist to get this PR merged as quickly as possible:

• [ ] Do all subcommands / options which take arguments include the args property (args: {})?
• [ ] Are all options modular? E.g. -a -u -x instead of -aux
• [ ] Have all other checks passed?

I would also like some feedback on my implementation of the connectediOSDevices generator, as I show a display name different from what's actually filled in to make it easier to read.
