aws Rekognition not initializing on iOS

there seems to be very little to no documentation for AWS iOS text recognition inside an image. I have gone through the process of AWS create IAM with permissions to do Rekognition etc, I created my "mobile app" on AWS from that profile, and I got a json file which is included in my project.

enter image description here

I am initializing the AWS "stack" with no problems also in App Delegate

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    AWSDDLog.add(AWSDDTTYLogger.sharedInstance)
    AWSDDLog.sharedInstance.logLevel = .info

    return AWSMobileClient.sharedInstance().interceptApplication(
        application,
        didFinishLaunchingWithOptions: launchOptions)
}

I get a crash in my ViewController :

    override func viewDidLoad() {
    super.viewDidLoad()

    let rekognitionClient = AWSRekognition.default() // CRASH HERE BOOM

    let sourceImage = UIImage(named: "corolla")

    let image = AWSRekognitionImage()
    image!.bytes = UIImageJPEGRepresentation(sourceImage!, 0.7)

    guard let request = AWSRekognitionDetectLabelsRequest() else {
        puts("Unable to initialize AWSRekognitionDetectLabelsRequest.")
        return
    }

    request.image = image
    request.maxLabels = 3
    request.minConfidence = 90

    rekognitionClient.detectLabels(request) { (response:AWSRekognitionDetectLabelsResponse?, error:Error?) in
        if error == nil {
            print(response!)
        }
    }

}

The crash shows this:

2018-07-27 11:22:10.064126-0400 Plater[13491:5229604] *** Terminating app due    to uncaught exception 'NSInternalInconsistencyException', reason: 'The service configuration is `nil`.

From what I can gather, it seems that I am somehow supposed to configure Rekognition inside of my json file? I did not see that option when the json file was being created on the AWS web site...

Any ideas?

I ran into the same issue trying to use a different AWS service. Adding the service to my awsconfiguration.json file like this worked:

"Rekognition": {
    "Default": {
        "Region": "us-east-1"
    }
}

Source: I couldn't find this in the documentation, but the SDK is open source
