Question

将我的所有AWS SDK加载到我的项目中以实现登录过程后，我收到此错误。所有文件都装得很好。有谁知道我可能错过了什么？

感谢您的帮助

在创建cognito用户池的实例之前，您应该使用控制台中提供的信息注册您的用户池。此信息是clientId，poolId和clientSecret。之后，您可以正确创建用户池实例。

例如，当应用启动时，您应该执行以下操作：

let poolName = "poolName"

// You should update the region to be the one where you created the pool
let serviceConfiguration = AWSServiceConfiguration(region: AWSRegionType.usWest2, credentialsProvider: nil)

let configuration = AWSCognitoIdentityUserPoolConfiguration(clientId: "Client Id found in the console here", clientSecret: "Client secret found in the console here", poolId: "Pool Id here")

AWSCognitoIdentityUserPool.register(with: serviceConfiguration, userPoolConfiguration: configuration, forKey: poolName)

之后，您可以通过执行以下操作获得对用户池的引用：

let userPool = AWSCognitoIdentityUserPool(forKey: poolName)

所有提到的信息都可以在用户池控制台中找到！

用户池未注册
