How do I reconnect and backoff on failures in Swift?

In Swift, implementing a reconnect and backoff strategy for handling failures is crucial, especially when dealing with network calls or server connections. This strategy involves retrying the connection after a specified interval, which increases after each failed attempt, until a maximum duration is reached.

Here's an example of how to implement a basic reconnect and backoff mechanism in Swift:


        // Swift Reconnect and Backoff Example

        import Foundation

        class ReconnectManager {
            private var retryCount = 0
            private let maxRetryCount = 5
            private var delay: Double = 1.0
            
            func connect() {
                // Your connection logic here
                print("Attempting to connect...")
                
                // Simulating a connection failure
                let success = Bool.random()
                
                if !success {
                    print("Connection failed. Retrying in \(delay) seconds...")
                    retryConnection()
                } else {
                    print("Connected successfully!")
                }
            }
            
            private func retryConnection() {
                guard retryCount < maxRetryCount else {
                    print("Max retry limit reached. Giving up.")
                    return
                }
                
                retryCount += 1
                // Increase delay for backoff
                delay *= 2
                
                DispatchQueue.global().asyncAfter(deadline: .now() + delay) {
                    self.connect()
                }
            }
        }

        let reconnectManager = ReconnectManager()
        reconnectManager.connect()
