Instantiate UIView from nib causes infinite loop issue

Question

I'm trying to use a custom view I created.

I use instantiation from nib, but it causes an infinite loop which I'm not sure how to fix. Any idea?

Here is the image of the run result:

And here's the code that causes the issue:

// MARK:  - Init & Setup
// Needed for IBDesignable



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

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

func setup(){
    view = loadViewFromNib()
    view.frame = bounds
    view.autoresizingMask = UIViewAutoresizing(rawValue: UIViewAutoresizing.RawValue(UInt8(UIViewAutoresizing.flexibleWidth.rawValue) | UInt8(UIViewAutoresizing.flexibleHeight.rawValue)))
    addSubview(view)
}

func loadViewFromNib() -> UIView{
    let bundle = Bundle(for:type(of: self))
    let nib = UINib(nibName: "LoginView", bundle: bundle)         // TEST: changin bundle from bundle-> nil

    let view = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
    return view
}

Edit: Here's an image of the connection

Thanks :)

Quick answer: Since the top-level view in the Xib had its custom class set to YourCustomeView, the xib loading process loadViewFromNib will then call your initWithCoder method again ⛔️🚫♽.

Quick fix: In the Xib, instead of setting the custom class of the view as YourCustomeView, set YourCustomeView as The File Owner of the Xib.
