AWS: DeveloperAuthenticatedIdentityProvider not firing IOS Swift

Question

I am trying to integrate S3 upload to upload a video file and tried Developer authenticated Identity method. Everything is configured as per the aws docs says.

DeveloperAuthenticatedIdentityProvider Class :

class DeveloperAuthenticatedIdentityProvider : AWSCognitoCredentialsProviderHelper {
    override func token() -> AWSTask<NSString> {
    //return AWSTask //with token and will set identityId
}

and then

let devAuth = DeveloperAuthenticatedIdentityProvider(regionType: COGNITO_REGION, identityPoolId: COGNITO_POOL_ID, useEnhancedFlow: true, identityProviderManager:nil)
let credentialsProvider = 
AWSCognitoCredentialsProvider(regionType: COGNITO_REGION, identityProvider:devAuth)

let configuration = 
AWSServiceConfiguration(region: S3_REGION, credentialsProvider:credentialsProvider)

AWSServiceManager.default().defaultServiceConfiguration = configuration

after configuring these things tried to upload using AWSS3TransferManager

let transferManager = AWSS3TransferManager.default()

let uploadingFileURL = URL(fileURLWithPath: "your/file/path/myTestFile.txt")

let uploadRequest = AWSS3TransferManagerUploadRequest()

uploadRequest.bucket = "myBucket"
uploadRequest.key = "myTestFile.txt"
uploadRequest.body = uploadingFileURL
transferManager.upload(uploadRequest).continueWith(executor: AWSExecutor.mainThread(), block: { (task:AWSTask<AnyObject>) -> Any? in

    if let error = task.error as? NSError {
        if error.domain == AWSS3TransferManagerErrorDomain, let code = AWSS3TransferManagerErrorType(rawValue: error.code) {
            switch code {
            case .cancelled, .paused:
                break
            default:
                print("Error uploading: \(uploadRequest.key) Error: \(error)")
            }
        } else {
            print("Error uploading: \(uploadRequest.key) Error: \(error)")
        }
        return nil
    }

    let uploadOutput = task.result
    print("Upload complete for: \(uploadRequest.key)")
    return nil
})

Whenever I call Upload method it shows

[Error Domain=com.amazonaws.AWSCognitoIdentityErrorDomain Code=8 "(null)" UserInfo={__type=NotAuthorizedException, message=Unauthenticated access is not supported for this identity pool.}]

also DeveloperAuthenticatedIdentityProvider not getting fired

kindly please help.

When you using Developer authenticated identity for cognito identity provider you need not use AWSS3TransferManager.default() You need to register the AWSServiceConfiguration to the AWSS3TransferManager with a key.

AWSS3TransferManager.register(with: configuration!, forKey: "KEY")

Try this way:

let devAuth = DeveloperAuthenticatedIdentityProvider(regionType:  COGNITO_REGION, identityPoolId: COGNITO_POOL_ID, useEnhancedFlow: true, identityProviderManager:nil)
    let credentialsProvider = AWSCognitoCredentialsProvider(regionType: COGNITO_REGION, identityProvider:devAuth)
    let configuration = AWSServiceConfiguration(region: S3_REGION, credentialsProvider:credentialsProvider)

    AWSS3TransferManager.register(with: configuration!, forKey: "YOUR_KEY")

//Start Upload

let uploadRequest = AWSS3TransferManagerUploadRequest()

 //Set all properties to uploadRequest

    AWSS3TransferManager.s3TransferManager(forKey: "YOUR_KEY").upload(uploadRequest!).continueWith(executor: AWSExecutor.mainThread(), block: { (task:AWSTask<AnyObject>) -> Any? in
                // Do something with the response

                if task.isCancelled {
                    print("Cancelled Upload")

                }
                else if (task.error != nil) {

                    print("Upload error --> \(task.error)")
                }else{

                    print("Upload success!!! Be happy :)")

                }
                return task
            })

Just try, I think it may work.
