Set up Info.plist

The first step to adding Multipeer Connectivity to any app is to ask for permission and tell users why it will use a local network. You'll use Info.plist for this.

Advertise a Device

In order to advertise your device to others, you'll need to use a reference to a Multipeer Connectivity Session object.

Invitations

Once your device is advertising that it’s available, you'll need to employ MCNearbyServiceAdvertiserDelegate to handle requests to connect to other devices.

Discovery

When you have devices advertised through Multipeer Connectivity, the next step is to discover them. For that, you can use an MCNearbyServiceBrowser object.

Send Data

With an MCSession on one device, you can send data. And on another, an MCSessionDelegate will receive it.

MCBrowserViewController

Multipeer Connectivity provides a standard UI that abstracts what can be achieved with MCNearbyServiceBrowser: MCBrowserViewController.

If you need a way to communicate wirelessly with Apple devices in close proximity to each other, in a blazing fast way, and you're quite comfortable with Swift, this course is likely a good match for you. SwiftUI and Combine knowledge will be helpful: they're both used in this course, but are not essential for employing Multipeer Connectivity.
