AWS Cognito Swift credentials provider “logins is deprecated: Use AWSIdentityProviderManager”

Question

Im trying to allow users to sign up with my app using facebook and Amazon Cognito. I found previous documentation saying to use:

    let token = FBSDKAccessT         


        

Answer 1

After looking around I finally found out I wasn't the only one with this issue. AWS updated their sdk without changing their main documentation. The solution is to implement the AWSCognitoIdentityProviderManager in a custom class and feed that to the credentials provider. Heres the code provided by simaomi in the github discussion below (its more of a quick fix):

import Foundation
import AWSCore
import AWSCognito
import AWSCognitoIdentityProvider
class CustomIdentityProvider: NSObject, AWSCognitoIdentityProviderManager{
    var tokens : [NSString : NSString]?
    init(tokens: [NSString : NSString]) {
        self.tokens = tokens
    }
    @objc func logins() -> AWSTask {
        return AWSTask(result: tokens)
    }
}


let customProviderManager = CustomIdentityProvider(tokens: logins!)

self.credentialsProvider = AWSCognitoCredentialsProvider(
   regionType: Constants.COGNITO_REGIONTYPE,
   identityPoolId: Constants.COGNITO_IDENTITY_POOL_ID,
   identityProviderManager: customProviderManager)

the sdk example shows how you should really implement the solution
