Finding tutorials for Swift Cognito Anonymous Login

I believe you're looking for Unauthenticated identities in Cognito. There is a document guide here: https://docs.aws.amazon.com/cognito/latest/developerguide/identity-pools.html#authenticated-and-unauthenticated-identities As well as a setup guide using AWS Amplify (guest access using swift) - https://docs.amplify.aws/lib/auth/guest_access/q/platform/ios/

Here is a documentation/guide that touches on using Cognito with a swift app. I hope it helps. https://aws.amazon.com/blogs/mobile/using-amazon-cognito-with-swift-sample-app-developer-guide-and-more/
