Do Combine and async await solve the same problems?

Combine and async/await in Swift are both used to handle asynchronous operations, but they approach the problem differently and are suited for different use cases.

Combine is a framework that provides a declarative Swift API for processing values over time. It is particularly useful for handling streams of data and is often used in reactive programming. Combine allows you to chain operations and transformations on data streams, making it ideal for scenarios where you need to handle multiple asynchronous events or data streams.

Async/await, on the other hand, is a language feature in Swift that simplifies writing and reading asynchronous code. It allows you to write asynchronous code that looks and behaves like synchronous code, making it easier to understand and maintain. Async/await is particularly useful for handling single asynchronous operations, such as network requests or file I/O, where you want to wait for a result before proceeding.

In summary, while both Combine and async/await are used for asynchronous programming, Combine is more suited for handling complex data streams and reactive programming, whereas async/await is ideal for simplifying the syntax and structure of asynchronous code. They solve different problems and can be used together in a Swift application depending on the specific needs of the task at hand.
