Simple code snippet today that show how to push a UIView and obtain the same effect of a UINavigationController as push action, choosing also the side (.fromLeft / .fromRight).

Send data between Apple devices (iPhone/iPad/macOS) using Multipeer Connectivity

In iOS, the framework uses infrastructure Wi-Fi networks, peer-to-peer Wi-Fi, and Bluetooth personal area networks for the underlying transport. In macOS and tvOS, it uses infrastructure Wi-Fi, peer-to-peer Wi-Fi, and Ethernet.”
