Использование UITableViewController и Cell with Parse

Question

Я следую этому руководству (https://www.youtube.com/watch?v=Q6qcrO8uNzU&feature=youtu.be). Ниже приведен код, который создается в конце. Однако для getShifts.findObjectsInBackgroundWithBlock { (objects:AnyObject[]!, error:NSError!) -> Void in

Я получаю сообщение об ошибке, которое говорит, что я должен положить AnyObject[]!, например [AnyObject]! ... но это просто создает больше ошибок. Есть идеи?

import UIKit 

class AvailableShifts: UITableViewController { 

var shiftData: NSMutableArray! 

override func viewDidAppear(animated: Bool) { 
    super.viewDidAppear(true) 

    loadData() 

    // Uncomment the following line to preserve selection between presentations 
    // self.clearsSelectionOnViewWillAppear = false 

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller. 
    // self.navigationItem.rightBarButtonItem = self.editButtonItem() 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated.

override func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
    // #warning Potentially incomplete method implementation. 
    // Return the number of sections. 
    return 1 
} 

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    // #warning Incomplete method implementation. 
    // Return the number of rows in the section. 
    return 2//shiftData.count 
} 


override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    let cell:AvailableShiftsCell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as AvailableShiftsCell 

    let shift: PFObject = shiftData.objectAtIndex(indexPath.row) as PFObject 

    cell.shiftLabel.text = shift.objectForKey("Shift") as String 

    // Configure the cell... 

    return cell 
}

Попробуйте следующее, Первое изменение в Верхней var shiftData: NSMutableArray! к var shiftData = [PFObject]()

и ваш Func LoadData()

func loadData() { 

    var getShifts = PFQuery(className: "Shifts") 

    getShifts.findObjectsInBackgroundWithBlock { 
    (objects: [AnyObject]!, error: NSError!) -> Void in 
    if error == nil { 

    var shiftData = objects as [PFObject] 
    self.shiftData = shiftData 
    var lastIndex = NSIndexPath(forRow: self.shiftData.count - 1, inSection: 0) 

    } 
} 
} 

и на cellForRowAtIndexPath

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
let cell = tableView.dequeueReusableCellWithIdentifier("Cell" as AvailableShiftsCell 
    let shift = self.shiftData[indexPath.row] 
     cell.shiftLabel.text = shift as String 

    return cell 
}
