Swift, Multiple Platform Tutorial

Hello Nick,

The course transfers lists between

MacOS computer,
iOS, iPad, iPhone, and
Watch.

Do you achieve this by storing and reading Jaon files by Bluetooth ?
Do you have an interface to a website, or by use of Firebase?

I am a Full Stack NextJS programmer and can store Json locally
and access MongoDB…

How do you communicate the data to each device-computer?

thank you,

James Avakian
