AlamofireEasyLogger is an easy drop-in Alamofire request & response logger. No configuration is needed, it just works.

It works for all requests and responses. There is no need to call a function on every request. It provides a full request/response logger out of the box and allows for easy overriding in case you have different requirements for what you want to see.


  • iOS 9.0+
  • Xcode 10.0+
  • Swift 4.2+



AlamofireEasyLogger is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'AlamofireEasyLogger'


Out of the box AlamofireEasyLogger provides the FancyAppAlamofireLogger class that logs request and responses with their parameters, headers and bodies as in the example below.

This works for both successful and unsuccessful requests/responses and the output is nicely formatted.

Usage in app

You need to hold a reference to your logger instance. The place to do this might be your AppDelegate or any other place where the reference will stay alive.

import UIKit
import AlamofireEasyLogger

class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
    let alamofireLogger = FancyAppAlamofireLogger(
        logFunction: {

As you can see above the only parameter the logger takes during initialization is logFunction closure defined as public typealias LogFunction = (String) -> Void. This function is responsible for logging the requests and responses. You can use a simple print as in the example above or integrate a logging library of your choice.

Implementing your own logger

If the FancyAppAlamofireLogger is too verbose for your taste or you want to implement a completely custom logger you can use the AlamofireLoggerDelegate of AlamofireEasyLogger.

Your logger should be used exactly like the FancyAppAlamofireLogger in the example above and should look similar to following piece of code.

class FancyAppAlamofireLogger: AlamofireLoggerDelegate {
    let alamofireLogger = AlamofireLogger()
    public init() {
        alamofireLogger.delegate = self
    open func networkRequestDidStart(request: AlamofireLoggerRequest) {
    open func networkRequestDidComplete(request: AlamofireLoggerRequest, result: AlamofireLoggerResult) {
    open func loggingFailed(error: AlamofireLoggingError) {

As you can see on this example AlamofireEasyLogger is quite versatile and with the use of AlamofireLoggerDelegate you're able to develop a completely custom logger while leveraging the AlamofireLoggerRequest, AlamofireLoggerResult and AlamofireLoggingError entities provided to you.
