Synchronous URL request on Swift 2

Question

I have this code from here to do synchronous request of a URL on Swift 2.

  func send(url: String, f: (String)-> ()) {
    var request = NSURLRequest(URL:         


        

Answer 1

Synchronous requests are sometimes fine on background threads. Sometimes you have a complicated, impossible to change code base full of async requests, etc. Then there is a small request that can't be folded into the current system as async. If the sync fails, then you get no data. Simple. It mimics how the file system works.

Sure it does not cover all sorts of eventualities, but there are lots of eventualities not covered in async as well.
