Getting the JSON data from cloudant - swift

Question

I have a database created in Cloudant and I am trying to parse that data in my Swift project. I have imported the Cloudant libraries, but I am not able to parse the data.
Here is the code that I Have been using till now
var url = "https://username:password#cloudant.com/dashboard.html#/database/db_2/login_details"
var request = NSMutableURLRequest()
request.URL = NSURL(string: url)
request.HTTPMethod = "GET"
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue(), completionHandler:{ (response:NSURLResponse!, data: NSData!, error: NSError!) -> Void in
var error: AutoreleasingUnsafeMutablePointer<NSError?> = nil
let jsonResult: NSDictionary! = NSJSONSerialization.JSONObjectWithData(data, options:NSJSONReadingOptions.MutableContainers, error: error) as? NSDictionary
if jsonResult != nil {
if let item = json[0] {
if let student_name = item["Student_name"] {
if let pasword = student_name["password"] {
println("Login Successfull")
}
}
}
}
}
Can somebody tell me where am I going wrong?

You should use stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding) to convert any special characters your link may have. Also NSURL may return nil so you need to use if let to handle it as follow :
if let link = "https://username:password#cloudant.com/dashboard.html#/database/db_2/login_details".stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding) {
if let checkedUrl = NSURL(string: link) {
println("valid Url")
// your code
} else {
println("invalid Url")
}
}
