FirstViewController does not conform to Protocol - ios

Question

I wrote this in Xcode 6 (Swift) but it says "Type 'FirstViewController' does not conform to protocol 'UITableViewDataSource'" and won't let me build the program. Please help?
import UIKit
class FirstViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//UIViewTableDataSource
func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int{
return taskMGR.tasks.count
}
func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) ->
UITableViewCell!{
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier:
"test")
cell.textLabel?.text = taskMGR.tasks[indexPath.row].name
cell.detailTextLabel?.text = taskMGR.tasks[indexPath.row].desc
return cell
}
}

Answer 1

As I wrote in the comments you might as well change the class to a UITableViewController subclass as it is basically the same as UIViewController + UITableViewDelegate + UITableViewDataSource (with a little bit of extra functionality included if you want it). It also has a UITableView property included "out of the box".
You will then end up with the following class:
class FirstViewController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//UIViewTableDataSource
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int{
return taskMGR.tasks.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier:"test")
cell.textLabel?.text = taskMGR.tasks[indexPath.row].name // You can remove ? when updating to XCode 6.1 / Swift 1.1
cell.detailTextLabel?.text = taskMGR.tasks[indexPath.row].desc
return cell
}
}

I rewrote your class to work. I deleted a couple of variables I did not need, but you can add them back. Key was to delete 'UITableViewDataSource' (you do not conform to this) and to unwrap the optional cell the way you wrote it. I prefer not to construct the cell that way, but that is another discussion. If you still have issues let me know.
import UIKit
class FirstViewController: UIViewController, UITableViewDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//UIViewTableDataSource
func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int{
return 1
}
func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) ->
UITableViewCell!{
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier:
"test")!
return cell
}
}
