Use AWS SDK
If you need functionality in the AWS services used by the Amplify Predictions category that isn't available, we provide an escape hatch so you can get a reference to that service.  For example, to get a reference to AWSRekognition:
guard let predictionsPlugin = try Amplify.Predictions.getPlugin(for: "awsPredictionsPlugin") as? AWSPredictionsPlugin else {    print("Unable to cast to AWSPredictionsPlugin")    return}
guard let rekognitionService = predictionsPlugin.getEscapeHatch(key: .rekognition) as? AWSRekognition else {    print("Unable to get AWSRekognition")    return}
let request = AWSRekognitionCreateCollectionRequest()if let request = request {    rekognitionService.createCollection(request)}In addition to AWSRekognition, this same pattern can be used to get access to AWSTranslate, AWSPolly, AWSTranscribeStreaming, AWSComprehend, and AWSTextract.  For example:
guard let translateService = predictionsPlugin.getEscapeHatch(key: .translate) as? AWSTranslate else {    print("Unable to get AWSTranslate")    return}
guard let pollyService = predictionsPlugin.getEscapeHatch(key: .polly) as? AWSPolly else {    print("Unable to get AWSPolly")    return}
guard let transcribeService = predictionsPlugin.getEscapeHatch(key: .transcribe) as? AWSTranscribeStreaming else {    print("Unable to get AWSTranscribeStreaming")    return}
guard let comprehendService = predictionsPlugin.getEscapeHatch(key: .comprehend) as? AWSComprehend else {    print("Unable to get AWSComprehend")    return}
guard let textractService = predictionsPlugin.getEscapeHatch(key: .textract) as? AWSTextract else {    print("Unable to get AWSTextract")    return}API Documentation Resources
