How do I apply exponential backoff for transient errors in Swift?

Exponential backoff is a standard algorithm used for error handling in network communications, where the retry interval increases exponentially with each failure. This method is particularly useful for managing transient errors that might resolve themselves after some time. In Swift, you can implement exponential backoff using an iterative loop that delays retries based on a calculated wait time.

The following Swift code snippet illustrates how to implement exponential backoff for transient errors:


        ```swift
        import Foundation

        func fetchDataWithExponentialBackoff(retries: Int = 5, initialDelay: TimeInterval = 1.0) {
            var attempts = 0

            func attemptFetch() {
                // Simulate a network request
                let success = Bool.random() // Simulating success or failure

                if success {
                    print("Data fetched successfully!")
                } else {
                    print("Error encountered. Attempt \(attempts + 1) of \(retries).")
                    attempts += 1

                    if attempts < retries {
                        let delay = initialDelay * pow(2.0, Double(attempts))
                        print("Retrying in \(delay) seconds...")
                        DispatchQueue.global().asyncAfter(deadline: .now() + delay) {
                            attemptFetch()
                        }
                    } else {
                        print("Max retry attempts reached. Please try again later.")
                    }
                }
            }

            attemptFetch()
        }

        // Call the function
        fetchDataWithExponentialBackoff()
        ```
