Getting to Grips with Combine

Reactive programming is a paradigm that involves designing systems that respond to changes in the input data and automatically update their output. In reactive programming, changes to the data are modeled as a stream of events, and operations are performed on these streams to produce new streams of updated data. This allows developers to write more concise and maintainable code by abstracting complex logic into simple operations on streams.

Combine is a reactive programming framework developed by Apple for use in iOS, iPadOS, and macOS development. It provides a set of APIs for processing values over time as well as handling events and data changes in a declarative and functional manner. Combine makes it easy to write reactive code by providing a wide range of operators and publishers that can be used to manipulate streams of data. It also provides a unified mechanism for handling errors and cancellations, making it easier to write robust and reliable...
