IBInspectable with Cocoa Touch Framework not working? (code attached)

Question

I can not seem to get the "titleText" IBInspectable attribute working. I have a simple framework view with a UILabel which I create an IBInspectable variable "titleText". I note the inspectable "layer" variables work as expected, but not my custom "titleText" which is supposed to update the main view using this framework.

Issues are:

1. Interface Builder not updating the titleLabel? (i.e. at design time) i.e. I'm expecting that this should, just like it is working for the "layer" items.

2. At Run Time the value of titleLabel is not picking up the value I set in IB either. Note that I get the following output when I run, i.e. my code that produces this is finding the "self.titleLabel" is actually nil??

CODE SUMMARY

(a) gcCustomView.xib Snapshot

(b) gcCustomerView.swift

import UIKit

@IBDesignable 
class gcCustomView: UIView {

    @IBOutlet weak var titleLabel: UILabel!
    @IBInspectable var titleText: String = "Default" {
        didSet {
            if  self.titleLabel != nil {
                self.titleLabel.text = titleText
            } else {
                NSLog("Could not set title text as label.text was nil : was trying to set to \(titleText)")
            }
        }
    }


    @IBInspectable var cornerRadius: CGFloat = 0 {
        didSet {
            layer.cornerRadius = cornerRadius
            layer.masksToBounds = cornerRadius > 0
        }
    }
    @IBInspectable var borderWidth: CGFloat = 0 {
        didSet {
            layer.borderWidth = borderWidth
        }
    }
    @IBInspectable var borderColor: UIColor? {
        didSet {
            layer.borderColor = borderColor?.cgColor
        }
    }


    override init(frame: CGRect) {
        super.init(frame: frame)
        commitInit()
    }

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

    // Private

    func commitInit() {
        if self.subviews.count == 0 {
            print("Loading Nib")
            //let bundle = Bundle(forClass: self.dynamicType)
            let bundle = Bundle(for: type(of: self))
            let nib = UINib(nibName: "gcCustomView", bundle: bundle)
            let view = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
            view.frame = bounds
            view.autoresizingMask = [.flexibleWidth, .flexibleHeight]
            addSubview(view)
        }
    }

}

Answer 1

Select gcCustomView.xib File's Owner change class name to gcCustomerView.

Right click on the Label drag from outlet to File Owner

Now It should look like this if you right click Label

I made a demo project. It is working ok. If you still have problem let me know. I'll upload my demo project in Github.
