Tengo un problema con aws. Hago todos los pasos desde https://console.aws.amazon.com/mobilehub/home?region=us-east-1#/75a98ed6-3ba6-4974-a3b2-4ba9c53a9b8f/source?platform=ios-swift&topic=u101

pero cuando construyo mi proyecto recibo muchos errores.

 Undefined symbols for architecture arm64: "_OBJC_CLASS_$_AWSS3PreSignedURLBuilder", referenced from: objc-class-ref in AWSMobileHubHelper(AWSContentManager.o) "_OBJC_CLASS_$_AWSS3ListObjectsOutput", referenced from: objc-class-ref in AWSMobileHubHelper(AWSContentManager.o) "_OBJC_CLASS_$_AWSS3GetPreSignedURLRequest", referenced from: objc-class-ref in AWSMobileHubHelper(AWSContentManager.o) "_OBJC_CLASS_$_AWSS3", referenced from: objc-class-ref in AWSMobileHubHelper(AWSContentManager.o)

Uso cocoapod para otras lib. pero para aws agrego sdk a mi proyecto.
