Swift UITableview display data from array

Question

I have a API that hands back a string of numbers based on a User. Once the API Request is made the function places the numbers into an Array.

var usernumbers = userResponse["Numbers"] as NSArray

The debugger PrintLn shows:

( 16467621007, 14152555613, 14046206007 )

When I hand this to UITableView, how do I split up the array so that each number goes into a separate cell? Ive tried:

let rowData: NSArray = tableData (usernumbers has been handed to table data)

I've tried:

cell.textLabel?.text = rowData.row (and all varieties of)

Where am I going wrong?

Can you show the implementation of your cellForRowAtIndexPath and numberOfRowsInSection methods? And you should be getting an error from rowData.row, since NSArray doesn't have a row property. — Mick MacCallum

If i understood your problem correctly, this is what you are looking for,

cell.textLabel?.text = rowData[indexPath.row] as String

Edit:

let numberValue : NSNumber = rowData[indexPath.row] as NSNumber

 let text : String = numberValue.stringValue // add  nil check

 cell.textLabel?.text = text

You can directly assign like

cell.textLabel?.text = numberValue.stringValue - if you are sure there won't be a nil value

When I use 'rowData[indexPath.row] as String' I get "Swift dynamic cast failed" so Im not converting from the Array into a string correctly.

Currently the func tableView code is: let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "MyTestCell") let rowData: NSArray = tableData cell.textLabel?.text = rowData[indexPath.row] as String return cell which fails on a 'Swift dynamic cast failed' error

Use rowData[indexPath.row] where indexPath.row is the current cell starting from 0

 private let data = Array(1...9)

then...

 func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
 return data.count
 }

and in your :

    func tableView(tableView: UITableView, cellForRowAtIndexPath 
    indexPath: NSIndexPath) -> UITableViewCell {...

all the usual stuff.

  cell.textLabel?.text = String(format: "the magic number is : %.f", data[indexPath.row])
  }
