SwiftyDropbox download to stream?

Hi -- I'm experimenting with developing a macOS SwiftyDropbox app which downloads and uploads encrypted files, decrypting them on the fly on the user's local machine.   I know there's a version o...

    The SwiftyDropbox SDK only provides the two download styles you mentioned: file and memory. You can find a basic example of each in the readme here.

     

    The memory option returns the file data as a Data object (in 'response.1' in the example linked above). The SDK unfortunately doesn't offer an option for returning the data as a Stream instead, but I'll pass this along as a feature request. I can't promise if or when that might be implemented though.

    Thanks -- I think it would be a very useful feature to add!

     

    Re the Data object -- is there a recommended maximum size for this kind of download, like the way uploads greater than 150Mb should be done as a session?  This will determine whether we try the Data approach and feed it through a stream, or stick with a file download and then decrypt and delete the original file.

      There isn't a particular maximum download size recommendation in this case. (The upload request limit you mentioned is due to a particular server-side limit with respect to reliability, which doesn't apply to downloads.)

       

      So, this would be up to you, likely mainly as a matter of how much memory on the device you're willing to have the app consume for this.
