Background download from app extension in SwiftyDropbox
Hi -- my macOS app was working fine when I was downloading from Dropbox in the main app, but once I added download calls from my FileProvider helper app, I started getting a string of errors.

Thanks for writing this up. First, for reference, can you let me know what version of SwiftyDropbox you have installed? If you're not using the latest version, currently v8.2.1, please upgrade to that and let me know if you're still seeing this issue. If so, please also share the snippet of code you're running to do the download that triggers this.
And thanks for letting us know about the issue with the documentation sidebar as well. I'll report that to the team.
Turns out I've been building against an old version (6.0.3); I'll upgrade to 8.2.1 and get back to you!
For what it's worth, the download code is fairly basic at this point:
logger.log("dbx_downloadWithProgress: Downloading" + filePath)
let destination: (URL, HTTPURLResponse) -> URL = { temporaryURL, response in
return destURL
}
self.client?.files.download(path: filePath, overwrite: true, destination: destination)
.response { response, error in
if let (responseMetadata, responseURL) = response {
completionHandler(responseURL, nil)
} else if let error = error {
print(error) // TBD: error handling!
self.logger.log("dbx_downloadConfig ERROR: \(error)")
completionHandler(nil, error) // TBD: need to map the passed-in error to a file-provider one
}
}
.progress { progressData in
// TBD: need to pass in and implement progress display callback
self.logger.log("dbx_downloadConfig PROGRESS: \(progressData)")
print(progressData)
}
Just want to confirm that upgrading to 8.2.1 fixed the main problem! There were additional issues with the downloaded temp files not saving and opening successfully, but those were down to a quirk of the Apple FileProvider -- it was making a "file modified" call to update a "file last used" field immediately upon opening, and I hadn't implemented that yet. But that's just unclear Apple documentation; the Dropbox code worked fine.

Thanks for following up. I'm glad to hear you got this working. I just wanted to report that we've fixed the SwiftyDropbox documentation.
