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
