Creating particle animations similar to the iMessage screen and bubble effects in iOS can be difficult. The main reason is that the Core Animation Emitter Layer that allows you to animate, emit and render particle effects is complex to set up and configure due to its large number of parameters. In this article, you will

Building applications such as online games and real-time chat has never been more straightforward since the standardization of the WebSocket protocol in 2011. Before that, most app experiences were plagued with manual refreshes to access the latest data available. Remember F5? Since then, most apps use WebSockets in some form to update their user interface

When coding iOS apps, we often create classes that manage a particular aspect of the application. For example, it's common to develop "manager" classes that encapsulate methods for interacting with a specific application aspect. These aspects commonly include the REST API, WebSockets, database, caching, notifications, chat, etc. That is what's called the Facade pattern, and
