How do I get the error message in Swift 2.0?

Question

I used this method very much in Swift 1.2: NSURLConnection.sendSynchronousRequest(:_:_:_) but this is apparently deprecated in iOS9. It still works however but now it uses the new Swift 2.0 Error Handling and I don't know how I will get the error message if it fails, ex. if time runs out.

I know I have to put it into a do-catch and then say try before the metho but I dont know how to catch the error message.

do {
    let data = try NSURLConnection.sendSynchronousRequest(request, returningResponse: nil)
    return data 
}
catch _ {
    return nil
}

Before I used NSError and then its description property, but now I have no clue.

Use automatic error variable, and you can cast it to NSError if you wish:

catch {
    let nsError = error as NSError
    print(nsError.localizedDescription)
}
