@alionthego Sorry for the delayed response. Here is the snippet you need:

import AWSAppSync

class MyCognitoUserPoolsAuthProvider: AWSCognitoUserPoolsAuthProvider {

    func getLatestAuthToken() -> String {
        var token: String? = nil
        pool.currentUser()?.getSession().continueOnSuccessWith(block: { (task) -> Any? in
            token = task.result!.idToken!.tokenString
            return nil
        }).waitUntilFinished()
        return token!
    }
}

// You can choose your database location, accessible by the SDK
let databaseURL = URL(fileURLWithPath:NSTemporaryDirectory()).appendingPathComponent(database_name)

do {
  // Initialize the AWS AppSync configuration
   let appSyncConfig = try AWSAppSyncClientConfiguration(url: "endpoint-url",
                                                         serviceRegion: "region",
                                                         userPoolsAuthProvider: MyCognitoUserPoolsAuthProvider(),
                                                         databaseURL: databaseURL)

    // Initialize the AWS AppSync client
    appSyncClient = try AWSAppSyncClient(appSyncConfig: appSyncConfig)
} catch {
    print("Error initializing appsync client. \(error)")
}

This feature has been added with SDK version 2.6.20+

Where is pool coming from? It's undefined.

It worked after updating all dependencies.
