How to set different expiration timeout for each NSURLRequest

Question

Is it possible to set different expiration timeout for each request?

The only way I found was to create a new NSURLSession with a different NSURLSessionConfiguration and change the timeoutIntervalForResource. Same thing with frameworks like Alamofire.

You absolutely can do this. You can set the value directly on an NSMutableURLRequest which can be passed into Alamofire.

let URL = NSURL(string: "https://httpbin.org/get")!
let mutableURLRequest = NSMutableURLRequest(URL: URL)
mutableURLRequest.timeoutInterval = 5.0

Alamofire.request(mutableURLRequest)
    .responseJSON { response in
        debugPrint(response)
    }

UPDATE

You cannot control the timeoutIntervalForResource per request. The timeout interval property on NSURLRequest is equivalent to timeoutIntervalForRequest on the NSURLSessionConfiguration. More details here.
