As personal utility I’ve created a new FlatUIColor Cocoapod framework.
Consist of a simple UIColor extension with a customized set of my favorite flat colors that I use very often.

Today I want to introduce an Apple framework, called Multipeer Connectivity.
“The Multipeer Connectivity framework supports the discovery of services provided by nearby devices and supports communicating with those services through message-based data, streaming data, and resources (such as files). 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.”
