Synchronous requests for Alamofire
-
iOS 9.0+ / Mac OS X 10.11+ / tvOS 9.0+ / watchOS 2.0+
-
Xcode 8.0+

Swift 3.0+
For Alamofire 4.0+:
pod 'Alamofire-Synchronous', '~> 4.0'
For Alamofire 3.0+:
pod 'Alamofire-Synchronous', '~> 3.0'
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")
}
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")
}
