What tasks and problems are simplified when using asynchronous methods with Async/Await?

Using Async/Await in iOS significantly simplifies working with asynchronous code, solving the following tasks and problems:

• Improving code readability and maintainability. Asynchronous code looks like synchronous, which makes understanding logic and debugging easier.
• Avoiding "callback hell". Instead of nested closures, you can write sequential code.
• Simplifying error handling. You can use familiar try/catch constructs for asynchronous operations.
• Managing sequence and parallelism. It's easy to write code that performs tasks sequentially or in parallel using await and async let.

Example:

func fetchUserData() async throws -> User {
    let data = try await fetchDataFromNetwork()
    return parseUser(data)
}

Task {
    do {
        let user = try await fetchUserData()
        print(user)
    } catch {
        print("Error: \(error)")
    }
}

Thus, Async/Await makes asynchronous programming more intuitive and less error-prone.
