AWS S3 Swift – Upload Image from camera or photolibrary

Using the s3transferutility we will upload images from your camera or photo library in swift. View the source on github

In this example We will have 2 buttons – Camera Upload and Picture Upload.

Depending on what is selected as the data source (camera or photo library) it will upload the file accordingly. If you use the camera button you will notice that we will have to create a temp directory when uploading the image, since there is no asset location for it on the device.

You can find more info in the aws sdk

  1. Can u pls send the project ……And my requirement is when i click the action sheet button then my image will be saved in the bucket….

  2. Hi Jose! I love your AWS swift series of articles. I’m trying to understand something: Say that your trying to make an app where users can upload pics/videos to S3. If you wanted to view pics/videos uploaded by a specific user, could you query AWS S3 in that way? So my understanding is you can store user data in AWS DynamoDB (w/Titan for graph based) and somehow link the userId attribute to media that you upload to S3?

    Thanks so much!

  3. Hey! Great tutorial! One question though: I am having problems with my ”
    expression.uploadProgress”. The complier says “AWSS3TransferUtilityUploadExpression has not member uploadProgress”. I seem to have everything linked up in my bridging header and stuff. Any help please?

    Thanks

  4. Hi there,
    I’m having some minor issues here.. It’s this part of the command that causes it.
    “express.uploadProgress”

    Error Prompt: AWSS3TransferUtilityUploadExpression has no member ‘uploadprogress’

    Can i enquire: what are the reasons and how do i get this resolve?

    let expression = AWSS3TransferUtilityUploadExpression()
    expression.uploadProgress = {(task: AWSS3TransferUtilityTask, bytesSent: Int64, totalBytesSent: Int64, totalBytesExpectedToSend: Int64) in
    dispatch_async(dispatch_get_main_queue(), {
    let progress = Float(totalBytesSent) / Float(totalBytesExpectedToSend)
    self.progressView.progress = progress
    // self.statusLabel.text = “Uploading…”
    NSLog(“Progress is: %f”,progress)
    })
    }

  5. Hi,

    I was able to compile and execute the script. The console says the upload has been a success but I do not see anything in the Amazon S3 server. Could you tell me what the cause of this problem is?

    Thanks

  6. Hi! I’m getting the following error:
    value of type ‘AWSS3TransferUtilityUploadExpression’ has no member ‘uploadProgress’.
    Do you have any idea as to why? If i comment that part, everything else works fine.

    1. Replace that line with
      let expression = AWSS3TransferUtilityUploadExpression()
      expression.progressBlock = { (task: AWSS3TransferUtilityTask, progress: NSProgress) in
      print(progress.fractionCompleted)
      }
