curl -L to get file contents from Box through Alamofire for Swift 3

I am trying to get the file contents on Box through their API in Swift.

curl -L https://api.box.com/2.0/files/file_id/content -H "Authorization: Bearer access_token"

returns the right contents, but

curl https://api.box.com/2.0/files/file_id/content -H "Authorization: Bearer access_token"

does not.
So the "-L" part seems to be critical.

So far I have

let headers = [
"grant_type": "client_credentials",
"Authorization": "Bearer \(token)",
"scope": "public"

Alamofire.request("https://api.box.com/2.0/files/file_id/content", headers: headers).responseJSON { responseFile in

if let dataFile = responseFile.result.value {
print("JSON: \(dataFile)")

How can I add the "-L" part to this?

The overall structure should be correct since I can successfully get the metadata for the file by removing "/content" from the url.

According to curl manual -L/--location argument means

If the server reports that the requested page has moved to a different location (indicated with a Location: header and a 3XX response code), this option will make curl redo the request on the new place.

So, I guess, you must check response statusCode and if it will be 3xx you need to handle redirects. Check Alamofire framework documentation about that.
