Alamofire+Synchronous

Synchronous requests for Alamofire

Requirements

iOS 9.0+ / Mac OS X 10.11+ / tvOS 9.0+ / watchOS 2.0+
Xcode 8.0+
Swift 3.0+

Installation

For Alamofire 4.0+:

pod 'Alamofire-Synchronous', '~> 4.0'

For Alamofire 3.0+:

pod 'Alamofire-Synchronous', '~> 3.0'

Known issues

If you execute synchronous requests from the main queue:

The following tasks in the main queue, including UI updates, won't be execute until the synchronous request finished. in Alamofire 4, methods downloadProgress and uploadProgress added a new parameter queue, and its default value is DispatchQueue.main. it's better to reset it as Non-main queue If you execute synchronous requests from the main queue.

example:

// from the main queue (**not recommended**):
let response = Alamofire.download("https://httpbin.org/stream/100", method: .get, to: destination).downloadProgress { progress in
    	// Codes at here will be delayed before the synchronous request finished running.
    	print("Download Progress: \(progress.fractionCompleted)")
    
    }.response()
    
if let error = response.error {
    print("Failed with error: \(error)")
}else{
    print("Downloaded file successfully")
}

// from the main queue (**not recommended**):
let response = Alamofire.download("https://httpbin.org/stream/100", method: .get, to: destination).downloadProgress(queue: DispatchQueue.global(qos: .default)) { progress in
		// Codes at here will not be delayed
        print("Download Progress: \(progress.fractionCompleted)")
    
        DispatchQueue.main.async {
            // code at here will be delayed before the synchronous finished.
        }
    
    }.response()
    
if let error = response.error {
    print("Failed with error: \(error)")
}else{
    print("Downloaded file successfully")
}

Usage

import Alamofire
import Alamofire_Synchronous

The usage differences between Alamofire and Alamofire_Synchronous: Simply remove parameters: queue and completionHandler in response* methods.

Example(For Alamofire 4.0+):

//get request and response json
let response = Alamofire.request("https://httpbin.org/get", parameters: ["foo": "bar"]).responseJSON()
if let json = response.result.value {
	print(json)
}

// post request and response json(with default options)
let response = Alamofire.request("https://httpbin.org/post", method: .post, parameters: ["foo": "bar"]).responseJSON(options: .allowFragments)
if let json = response.result.value {
    print(json)
}

// download
let response = Alamofire.download("https://httpbin.org/stream/100", method: .get, to: destination).response()
if let error = response.error {
    print("Failed with error: \(error)")
}else{
    print("Downloaded file successfully")
}
