The | character its not a valid URL character so you must replace it with percent escape character. Encoding whole string will do that automatically for you 

var stringUrl = "https://roads.googleapis.com/v1/snapToRoads?path=-35.27801,149.12958|-35.28032,149.12907"

let URL = NSURL(string: stringUrl.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!)!
