Cannot find type 'AWSS3TransferManagerUploadRequest' in scope

Question

I am new in Swift. Since I update podfile I am facing issue in AWSS3

Cannot find type 'AWSS3TransferManagerUploadRequest' in scope
Cannot find type 'AWSS3TransferManagerDownloadRequest' in scope

There is also import AWSS3 in ViewController.

I am not understanding the problem. Did someone face the same issue?

I also check this https://stackoverflow.com/questions/32659346/awss3transfermanageruploadrequest-in-xcode-7

But it does not help.

    var uploadRequests = Array<AWSS3TransferManagerUploadRequest?>()

My code is like this I am getting issue since I update the podfile.I am facing issue in AWS3 as it is updated. I need to know what to replace.

Answer 1

You need to downgrade your AWSS3 pod version. Check the pod folder to see if the tool you're using is there (In my case, AWSS3TransferManager.h was missing from current version, downgraded to a version that had it).

Answer 2

If you're using Swift package manager to add the package, make sure you use the github url https://github.com/aws-amplify/aws-sdk-ios-spm.git, not https://github.com/awslabs/aws-sdk-swift.git.

Answer 3

I coped with the same problem when I was integrating the pod named AWSS3.

I fixed it by installing the specific version of these pods. Please check this URL https://cocoapods.org/pods/AWSS3#changelog

In my case, I installed the v2.16.0.

I think it is concerning with the Xcode version.

pod 'AWSS3', '~> 2.16.0'

I hope this helps you.
