OS X addsubview from xib in swift

Question

I'm trying to add a new sub view form a nib using swift for OS X.

So far i've:

• created a new "Cocoa Application"
• added a new "Cocoa Class" called "TestSubView" as a subclass of NSViewController with a XIB file

I want to add this subview to my main view when the application loads.

in my ViewController ( the ViewController for the main window ) i have.

import Cocoa

class ViewController: NSViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let newSubView = TestSubView();
        self.view.addSubview(newSubView.view);

    }

    override var representedObject: AnyObject? {
        didSet {
        // Update the view, if already loaded.
        }
    }


}

But i'm getting the following error

Failed to set (contentViewController) user defined inspected property on (NSWindow): 
-[NSNib initWithNibNamed:bundle:] could not load the nibName: temp.TestSubView in bundle (null).

I realise i will need to size and position this subview but I can't seem to get to that point.

I've spent the better part of a day trying to figure this one out so any help would be greatly appreciated.

Answer 1

I finally got this thing to work. My new code looks like

import Cocoa

class ViewController: NSViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let subview = TestSubView(nibName: "TestSubView", bundle: nil)!
        self.view.addSubview(subview.view)
    }

    override var representedObject: AnyObject? {
        didSet {
        // Update the view, if already loaded.
        }
    }

}

Found with the help of the docs & this answer

It was suggested that if the nib name and the class name are the same you shouldn't need to declare nibname: (as i'd tried to do originally) but the docs didn't mention this - explains why it didn't work!

For prosperity, this worked for me with Xcode 6.1.1 on OS X Yosemite (10.10.1)
