Array with key in swift - uitableview

Question

i am using this code to get text from array with key
This code in view did load
if let rs = db.executeQuery("select * from myTable", withArgumentsInArray: nil) {
while rs.next() {
let id = rs.stringForColumn("id")
let text1 = rs.stringForColumn("text")
dataArray.addObjectsFromArray(NSArray(objects:NSDictionary(object:NSArray(objects: id, text1), forKey:NSArray(objects: "id", "texti"))))
}
} else {
println("executeQuery failed: \(db.lastErrorMessage())")
}
...
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
cell.textLabel?.text = dataArray[indexPath.row].objectForKey("texti") as? String
return cell
}
The cell label text is null, why?
println("dataArray: \(dataArray)")
dataArray: (
{
(
id,
texti
) = (
1,
John
);
},
{
(
id,
texti
) = (
2,
Mark
);
},
{
(
id,
texti
) = (
3,
Marry
);
}
)
Is there a problem in this?
I am using same code in objective-c and its working probably

Call self.tableView.reloadData() after you retrieve the dataArray. Change the dataArray.addObjects line to
dataArray.addObject(["id":id,"texti" : text1])
if let rs = db.executeQuery("select * from myTable", withArgumentsInArray: nil) {
while rs.next() {
let id = rs.stringForColumn("id")
let text1 = rs.stringForColumn("text")
dataArray.addObject(["id":id,"texti" : text1]) // Added Line
}
self.tableview.reloadData() //Added Line
} else {
println("executeQuery failed: \(db.lastErrorMessage())")
}
Inside cellForRowAtIndexPath
if let txt = dataArray[indexPath.row].objectForKey("texti") as? String
{
cell.textLabel?.text = txt
}
