Class "ViewController" does not have an initializer error: xcode Beta 4

Question

I get this error in a file that works earlier on all other beta versions, for some reason in the 4-beta beta it displays this error, its the only file in the whole project that does this, and I'm not sure why is he only doing this for beta 4, any ideas? I tried using init by default, but I get a compilation error.

I think there is too much code to post, so instead the file directly.

Answer 1

From SwiftSoda.com:

Many Swift programmers have small issues with ViewControllers and Xcode beta 4. Error: viewController is not constructive with ().

But if you look at your view controller, you will see another error: Class viewController has no initializers. Following it (replace any outputs that you use) NSTextField has an optional type of "NSTextField".

Setting IBOutlets with? the end fixes the problem. After that, you will need to change some syntax every time the Outlets variable is used with !.

Here is a quick 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!" } } 

Answer 2

There was the same error because one of my properties was not initialized. Hope this helps some nations.

Answer 3

I find the easiest way is to simply override the init function without the 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) } 

Answer 4

you can safely expand any options using the IBOutletName statement:

 if mvc.myStatusField { mvc.myStatusField!.stringValue = "Swift Soda wishes you a good day!" } 

This way your application will not crash.

Am I trying to get IBOutlets to work without use? and! (optionals), but so far this seems to be the only thing that works in beta with NSViewController.

Implement below in your view controller:

 required init(coder aDecoder: NSCoder) { super.init(coder: aDecoder) }
