Class 'ViewController' has no initializers error: xcode Beta 4

Question

I'm receiving this error on a file which works previously on all other beta's, for some reason in the beta 4 xcode it displays this error, its the only file in the entire project which does it and i'm not sure why its doing it just for beta 4, any ideas? i've tried using the default init on it but i get a compile error.

i think theres too much code to place in, so instead heres the file direct.

From SwiftSoda.com:

Many Swift Programmers are having a little trouble with ViewControllers and Xcode beta 4. The error is viewController is not constructible with ().

But if you look at your View Controller, you will see another error, Class viewController has no initializers. Followed by (replace with whichever outlets you are using) NSTextField has non-optional type ‘NSTextField’.

Setting the IBOutlets with ? the end corrects the problem. After that you will need to change some syntax each time the Outlet’s variable is used with !.

Here is a brief example:

//ViewController Class File:
// view controller swift file for OS X
import AppKit

// you can use () for AnyObject as long as you do some things first.
var mvc = vc()

class vc: NSViewController {
// the key here is "?" after NSTextField to declare an optional
@IBOutlet var myStatusField: NSTextField?
}

//AppDelegate File:
import AppKit

//here we load the view inside the AppDelegate
class AppDelegate: NSObject, NSApplicationDelegate {

@IBOutlet var window: NSWindow!

func applicationDidFinishLaunching(aNotification: NSNotification?) {
// Insert code here to initialize your application

//load and center view in main window
window.contentView.addSubview(mvc.view)
mvc.view.frame = window.contentView.bounds

//here we display some text in myStatusField with *!.stringValue
// ! is used to unwrap the optional.
mvc.myStatusField!.stringValue = "Swift Soda wishes you a good day!"
}
}

Had the same error because one of my properties was not initialized. Hope it helps some peoples

Answer 3

I believe the easiest way is just override an init function without override keyword and just call super.init, and it works like this

@IBOutlet weak var tableView: UITableView!

init(nibName nibNameOrNil: String!, bundle nibBundleOrNil: NSBundle!) {
    super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)

}
