Amazon AWS AWSCognitoCredentialsProvider initializing error

Hi I am trying to initialize to create a default service configuration by adding the following code snippet in the Application delegate of an iOS 8 Swift app.

As directed on the amazon tutorial here http://ift.tt/1jMcsAv use the following lines of code

//AWS Service Config
    let credentialsProvider = AWSCognitoCredentialsProvider(
        regionType: AWSRegionType.USEast1, identityPoolId: "us-east-13453454-92d1-234234-234234-3434")

    let defaultServiceConfiguration = AWSServiceConfiguration(
        region: AWSRegionType.USEast1, credentialsProvider: credentialsProvider)

    AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = defaultServiceConfiguration

However the code will not compile as xCode says I am "Missing argument for IdentityId in Call"

First off this code is directly from amazons tutorial and also I do not have an identiyID just an identitypooolid (which is scrambled in my code).

What can I do to resolve this?

Thank you, Jack
