适用于iOS的AWS开发工具包：从Swift 2到Swift 3的转换问题

Question

I have downloaded the AWS SDK for iOS examples and opened them in XCode 8. Unfortunately there were lots of compiler errors due to the conversion from Swift 3. I fixed most of these but some functions still need fixing.

I am surprised that there is no official example from Amazon using Swift 3.

• What has been your approach?
• Did you go on fixing all these errors or has any of you found an example for Swift 3?

I am particularly interested in this sub-part of the repository: https://github.com/awslabs/aws-sdk-ios-samples/tree/master/S3TransferUtility-Sample/Swift/

EDIT:

I am testing the Objective-C version of the project as a proof of concept. Unfortunately when I run it I get the following error:

Connection = "keep-alive";
"Content-Length" = 451;
"Content-Type" = "application/x-amz-json-1.1";
Date = "Fri, 13 Jan 2017 15:59:58 GMT";
"x-amzn-ErrorMessage" = "2 validation errors detected: Value 'arn:aws:cognito-idp:eu-west-1:99999999999:userpool/eu-west-1_XXXXXXXXX' at 'identityPoolId' failed to satisfy constraint: Member must have length less than or equal to 55; Value 'arn:aws:cognito-idp:eu-west-1:99999999999:userpool/eu-west-1_XXXXXXXXX' at 'identityPoolId' failed to satisfy constraint: Member must satisfy regular expression pattern

It puzzles me as I thought I had configured the identity pool correctly in the Info.plist file.

See below (the details of the pool are hidden partially, but they are the same as the ones that the Database administrator gave me).

Any ideas of why this is happening?

Literal message says that identityPoolId' failed to satisfy constraint but I am not convinced about this. It could be that there is some configuration missing on the server side.

Unfortunately the documentation is not complete and I am a bit lost at the moment (feels like a waste of time).
