How to create a wrapper for Alamofire and SwiftyJSON? Swift – iOS

This blogpost updated with Swift 3 – Xcode 8 – iOS 10 – Alamofire 4.0

I have posted a basic tutorial about Alamofire and SwiftyJSON How to use Alamofire and SwiftyJSON with Swift?
And some day before we have learned about Use of Blocks(Closures) or Completion Handlers with Function in Swift – iOS
Let’s combine both the topics to make a WRAPPER of Alamofire and SwiftyJSON.

Let’s Begin to Wrap

Create an NSObject class

Go to File > New > File… and add a Swift NSObject class

Swift

import UIKit class AFWrapper: NSObject { }

1 2 3

import UIKit class AFWrapper: NSObject { }

Import respective modules/frameworks

Import the frameworks that you want to use with this wrapper.

Swift

import Alamofire import SwiftyJSON

1 2	import Alamofire import SwiftyJSON

Create a Function

Create a function with the use of Completion Handler/Closures/Blocks
Following is a sample of GET URL call with Alamofire and response object will be return to a success or failure closure/block respectively. If response is success then return a SwiftyJSON object with the success block.

Swift

class func requestGETURL(_ strURL: String, success:@escaping (JSON) -> Void, failure:@escaping (Error) -> Void) { Alamofire.request(strURL).responseJSON { (responseObject) -> Void in print(responseObject) if responseObject.result.isSuccess { let resJson = JSON(responseObject.result.value!) success(resJson) } if responseObject.result.isFailure { let error : Error = responseObject.result.error! failure(error) } } }

1 2 3 4 5 6 7 8 9 10 11 12 13

class func requestGETURL(_ strURL: String, success:@escaping (JSON) -> Void, failure:@escaping (Error) -> Void) {     Alamofire.request(strURL).responseJSON { (responseObject) -> Void in         print(responseObject)         if responseObject.result.isSuccess {             let resJson = JSON(responseObject.result.value!)             success(resJson)         }         if responseObject.result.isFailure {             let error : Error = responseObject.result.error!             failure(error)         }     } }

That’s It. Let’s Use It

By this way we can use the code reusability.
Following is the sample with the use of the wrapper :

Gist with Alamofire-SwiftyJSON – GET and POST Requests

In addition you can also integrate the Loader/HUD with the web service call to display web service is processing right now.
Happy Coding 🙂
