AWS: DeveloperAuthenticatedIdentityProvider not firing IOS Swift - ios

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.
