I wish this help you I'm trying now for the whole weekend to get simple data back from mysql database into Json into my app into a nice UItextview. , If your output from the log is this:
code :
Dictionary data {
users =     (
        {
    0 = 1;
    1 = "dani\t";
    10 = "";
    11 = "";
    12 = 0;
    2 = "l\f)\U008f\U00d0\U00b7`\U00fcR\U0092\U00bauU\U00f2]";
    3 = dani;
    4 = dani;
    5 = "";
    6 = "";
    7 = "";
    8 = dani;
    9 = dani;
    Country = "";
    Email = "dani\t";
    "First_Name" = dani;
    }
)}
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsondata options:0 error:&error];

NSArray *users = [dic objectForKey:@"users"];
NSDictionary  *firstUser = [users objectAtIndex:0];
user_mail.text = [NSString stringWithFormat:@"%@", [firstUser valueForKey: @"Email"]];

this one helps. I am fairly new to iOS development, been at it for 2 years or so. I have developed an app for my Litecoin mining pool that is able to pull data from the API url in JSON format. I am able to get individual variables from JSON, but I want to display all of the data from the "workers" block into a UITableView. Here is an example of the JSON: , Following code will print worker's information:
code :
[json[@"workers"] enumerateKeysAndObjectsUsingBlock:^(NSString *key, NSDictionary *obj, BOOL *stop) {
    NSLog(@"worker = %@  : hashrate = %f last_share_timestamp = %f",
          key, [obj[@"hashrate"] floatValue], [obj[@"last_share_timestamp"] floatValue] );
}];

hop of those help? I got a NSDictionary and I want to print it into a UITextView. , you should append it to the existing text
code :
textview.text = @"";

  for(int i=0; i<[array count];i++)
{
        dictionary= [array objectAtIndex:i];
        //that shows only one line from the dictionary in the textview
        textview.text = [textview.text stringByAppendingFormat:@"%@\n",[diction objectForKey:@"text"]]];

        //that shows all the dictionary with key "text" in the log
        NSLog(@"%@",[diction objectForKey:@"text"]);
}

I think the issue was by ths following , to get formatted JSON string.
The solution is to create JSON Object from JSON string,
code :
let jsonString = "[{\"person\": {\"name\":\"Dani\",\"age\":\"24\"}},{\"person\": {\"name\":\"ray\",\"age\":\"70\"}}]"

var error: NSError?

//1. convert string to NSData
let jsonData = jsonString.dataUsingEncoding(NSUTF8StringEncoding)!

//2. convert JSON data to JSON object
let jsonObject:AnyObject = NSJSONSerialization.JSONObjectWithData(jsonData, options: nil, error: &error)!

//3. convert back to JSON data by setting .PrettyPrinted option
let prettyJsonData = NSJSONSerialization.dataWithJSONObject(jsonObject, options: .PrettyPrinted, error: &error)!

//4. convert NSData back to NSString (use NSString init for convenience), later you can convert to String.
let prettyPrintedJson = NSString(data: prettyJsonData, encoding: NSUTF8StringEncoding)!

//print the result
println("\(prettyPrintedJson)")

I wish this help you I have the following code, where the global variable var fullDict = "" stores dictionary of values. , Based on your comments, you have put the line:
code :
userResult_txtView.text = self.fullDict
class ViewController: UIViewController {

    ...

    func showFullDict() {
        userResult_txtView.text = self.fullDict
    }
}

will help you For dictionary access, you should ideally be using objectForKey:, not valueForKey: (which has to do with key-value coding).
I don't know what your original JSON looks like, but if it is like:
