Alamofire Swift 2.0 <unknown>:0: error: tuple pattern cannot match values of the non-tuple type 'Response<String, NSError>' - alamofire

Question

I am using Manger class for request. When I compile it shows
<unknown>:0: error: tuple pattern cannot match values of the non-tuple type 'Response<String, NSError>' Error`.
Its working fine in old Swift Xcode 6.*. But in Xcode 7.* its not working.
let aManager = Manager.sharedInstance
aManager.request(.GET, URLStrings.BASE_URL + URLStrings.CATEGORIES)
.responseString { _, _, result in
print("Response String: \(result.value)")
}
.responseJSON { _, _, result in
print("Response JSON: \(result.value)")
}
On clicking responseString it shows ?
Kindly Help me.

Answer 1

I supposed that you are using the 3.0+ Alamofire.
I encounter this problem recently, here is my solution:
for you code replace _, _, result to response and query the response data by response.data or response.result.value
For more information about the new response structure, you can check the official document here: enter link description here
Hope these helps.

Answer 2

You're on the Alamofire 3.0.0-beta.1 pre-release. You should switch back to Alamofire 2.0.2 (the latest release) until we have all the documentation and migration guides up-to-date.

I change my code in to this form. Now What I have to do is Convert data to JSon Object my self. But its working now for me.
let aManager = Manager.sharedInstance
aManager.request(.GET, URLStrings.BASE_URL + URLStrings.CATEGORIES )
.response {
(request, response, data, error) in
if let response = response {
print("GET REQUEST: \(request?.description)")
print("GET REQUEST: \(response.statusCode)")
if response.statusCode == 200 || response.statusCode == 201 {
}
}
else {
}
}

Answer 4

I check the official document here: Response Serializers
In the document, find Response Serializers, read the example code, I post it in here:
Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["foo": "bar"])
.responseJSON { response in
debugPrint(response) // prints detailed description of all response properties
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
if let JSON = response.result.value {
print("JSON: \(JSON)")
}
}
Hope it can helps you~
