我正在尝试从https://github.com/awslabs/aws-sdk-ios-samples/tree/master/CognitoSync-Sample/Swift运行此AWS cognito示例应用。我可以添加新的数据集，但是一旦我尝试同步/刷新，我就会得到以下错误。我没有尝试任何提供商。只是简单的数据同步。
以下是我做的步骤 -
1.从github下载示例应用程序。
2.使用pod命令安装AWSCognito
3.并在Amazon Cognito控制台中创建了一个身份池
4.并更新了Constants.swift中的常量 -
static让COGNITO_REGIONTYPE = AWSRegionType.USEast1 static让COGNITO_IDENTITY_POOL_ID =“us-east-1_XXXXXXXXX”
以下是我的控制台的错误 -

我缺少什么？我是AWS服务的新手，我们非常感谢任何指导。
谢谢， Richa

我使用的是用户池ID，而不是身份池ID。它现在解决了。
答案 1 :(得分：0)
是的，这几乎总是使用用户池ID而不是标识池。
请注意，如果您在初始化AWSCognitoCredentialsProvider（）时输入正确的标识池ID，它将在模拟器中工作，即使您的info.plist AWS字典描述符中的ID错误也是如此。但是在设备上，它将使用info.plist池ID，如果错误则会失败。这点我，所以确保你的池ID在两个位置都是正确的。
