ios - Swift 3 - Rest Api HTTP Header Values are not being sent -


i'm trying build app swift, makes rest api call authorization header. code looks this:

var request = urlrequest(url: url!)     request.httpmethod = "get"     request.addvalue("application/json", forhttpheaderfield: "content-type")     request.addvalue("application/json", forhttpheaderfield: "accept")     request.addvalue("username:password", forhttpheaderfield: "authorization")     request.addvalue("de", forhttpheaderfield: "content-language")      urlsession.shared.datatask(with: request) { (data, response, error) in      ...      ...

my problem http header values somehow not being sent. verified requests values being set printing out request.allhttpheaderfields, response server still holds default values headers. not authorization header other header try change.

it great if can find mistake... mean, simple piece of code, i'm confused went wrong.
