State your question When following the readme, and making the changes on the iOS demo application, the device never connects to the IoT Service.

This is my output

****The x's are the actually values for the endpoint from AWS

Which AWS Services are you utilizing? Cognito and IoT Provide code snippets (if applicable) awsconfiguration.json { "Version": "1.0", "IdentityManager": { "Default": {} }, "CredentialsProvider": { "CognitoIdentity": { "Default": { "PoolId": "us-west-2:", "Region": "us-west-2" } } } }

Constants.swift import Foundation import AWSCore

//WARNING: To run this sample correctly, you must set the following constants.

let CertificateSigningRequestCommonName = "AWS IoT iOS Application" let CertificateSigningRequestCountryName = "US" let CertificateSigningRequestOrganizationName = "Organization" let CertificateSigningRequestOrganizationalUnitName = "Unit Name" let PolicyName = "TestApp1"

// This is the endpoint in your AWS IoT console. eg: https://xxxxxxxxxx.iot..amazonaws.com let AWSRegion = AWSRegionType.USWest2 // e.g. AWSRegionType.USEast1 let IOT_ENDPOINT = "https://xxxxxxxxxxxxxxxx.iot.us-west-2.amazonaws.com" let ASWIoTDataManager = "MyIotDataManager"

How can you solve this problem? I also have this problem.

I figured it out. If you attempted the connection, and one of the credentials was incorrect, it creates some variable that stores the info for future connection attempts. I made sure the credentials were correct, also permissions on the AWS server, and uninstall the app, then reinstall. It worked!
