Class has no initializers Swift

Question

I have a problem with Swift class. I have a swift file for UITableViewController class and UITableViewCell class. My problem is the UITableViewCell class, and outlets. This class has an error Class "HomeCell" has no initializers, and I don't understand this problem.

Thanks for your responses.

import Foundation
import UIKit

class HomeTable: UITableViewController, UITableViewDataSource, UITableViewDelegate {

    @IBOutlet var tableViex: UITableView!

    var items: [(String, String, String)] = [
        ("Test", "123", "1.jpeg"),
        ("Test2", "236", "2.jpeg"),
        ("Test3", "678", "3.jpeg")
    ]

    override func viewDidLoad() {
        super.viewDidLoad()

        var nib = UINib(nibName: "HomeCell", bundle: nil)
        tableView.registerNib(nib, forCellReuseIdentifier: "bookCell")
    }

    // Number row
    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.items.count
    }

    // Style Cell
    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("bookCell") as UITableViewCell

        // Style here

        return cell

    }

    // Select row
    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        // Select
    }

}

// PROBLEM HERE
class HomeCell : UITableViewCell {

    @IBOutlet var imgBook: UIImageView
    @IBOutlet var titleBook: UILabel
    @IBOutlet var pageBook: UILabel

    func loadItem(#title: String, page: String, image:String) {
        titleBook.text = title
        pageBook.text = page
        imgBook.image = UIImage(named: image)
    }

}

Answer 1

You have to use implicitly unwrapped optionals so that Swift can cope with circular dependencies (parent <-> child of the UI components in this case) during the initialization phase.

@IBOutlet var imgBook: UIImageView!
@IBOutlet var titleBook: UILabel!
@IBOutlet var pageBook: UILabel!

Read this doc, they explain it all nicely.
