Upload pdf(using swift sdk) is damaged when downloading from dropbox

[hzy916]

I am following the instructions on https://github.com/dropbox/SwiftyDropbox#download-style-request

and I successfully upload my pdf to dropbox. However the uploaded pdf cannot be previewed and when I download, it shows the following error. 

I tired to upload the same pdf manually to dropbox. I can preview and when I download it, it is completely correct. 

This is how I upload my pdf using swift. 

 

Appreciate anyone's help! Thank you very much. I have been stuck for a long time

Hello @hzy916,

I think the issue here is that you're trying to encode the PDF file as if it were text data and not binary data.

Try creating a URL to the local file path and updating your request to point the 'input' parameter directly to that URL.

See if that works as expected.
