ImagesTabViewController' does not conform to protocol 'UITableViewDataSource' - ios

Question

I know this question has been asked a million times, but I can't find a resolution to this specific issue. I'm using Xcode 6.3 beta 4 with Swift 1.2 and since the last update I haven't been able to get a regular UITableView with the supporting datasource and delegate protocols working.
I am getting the above error and "Definition conflicts with previous value" for the numberOfRowsInSection function. At this point I don't know if it's a Swift change or I am missing something. The tableview is connected properly..
Thanks for any help.
class ImagesTabViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var collectionInfo: NSArray = DataManager.getUserCollections()
var items: NSMutableArray = []
var namesArray: NSMutableArray = []
override func viewDidLoad() {
super.viewDidLoad()
APIManager().getData() { completed in
dispatch_async(dispatch_get_main_queue(), { () -> Void in
if completed {
self.collectionInfo = DataManager.getUserCollections()
var collectionNames: AnyObject = self.collectionInfo[3]
println(collectionNames)
self.items = NSMutableArray(array: self.collectionInfo)
} else {
//do something else
}
})
// Do any additional setup after loading the view.
}
func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Potentially incomplete method implementation.
// Return the number of sections.
return 1
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var collectionsAndArrays = PSCollection()
let cell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "cell")
// Configure the cell...
collectionsAndArrays = self.items[indexPath.row] as! PSCollection
cell.textLabel!.text = collectionsAndArrays.name
cell.detailTextLabel!.text = collectionsAndArrays.created_at
return cell
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete method implementation.
// Return the number of rows in the section.
var numberOfCollections: Int = self.items.count
return numberOfCollections
}
}}

There is a bracket missing and didReceiveMemoryWarning must be overridden. Here is the revised code:
class ImagesTabViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var collectionInfo: NSArray = DataManager.getUserCollections()
var items: NSMutableArray = []
var namesArray: NSMutableArray = []
override func viewDidLoad() {
super.viewDidLoad()
APIManager().getData() { completed in
dispatch_async(dispatch_get_main_queue(), { () -> Void in
if completed {
self.collectionInfo = DataManager.getUserCollections()
var collectionNames: AnyObject = self.collectionInfo[3]
println(collectionNames)
self.items = NSMutableArray(array: self.collectionInfo)
} else {
//do something else
}
})
// Do any additional setup after loading the view.
}
} // <- Was missing!
// Override!
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var collectionsAndArrays = PSCollection()
let cell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "cell")
// Configure the cell...
collectionsAndArrays = self.items[indexPath.row] as! PSCollection
cell.textLabel!.text = collectionsAndArrays.name
cell.detailTextLabel!.text = collectionsAndArrays.created_at
return cell
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
var numberOfCollections: Int = self.items.count
return numberOfCollections
}
}
