Initialize Swift subclass of UIView, designed in .xib

gistfile1.swift

// Create CustomView.xib, set File's Owner to CustomView. 
// Link the top level view in the XIB to the contentView outlet.

class CustomView : UIView {
    @IBOutlet private var contentView:UIView?
    // other outlets
    
    override init(frame: CGRect) { // for using CustomView in code
        super.init(frame: frame)
        self.commonInit()
    }
    
    required init?(coder aDecoder: NSCoder) { // for using CustomView in IB
        super.init(coder: aDecoder)
        self.commonInit()
    }
    
    private func commonInit() {
        Bundle.main.loadNibNamed("CustomView", owner: self, options: nil)
        guard let content = contentView else { return }
        content.frame = self.bounds
        content.autoresizingMask = [.flexibleHeight, .flexibleWidth]
        self.addSubview(content)
    }
}

thanks for the code

Hi all
I need to send extra two parameters in CustomView class from the viewcontroller class , How this is possible.

There's a memory leak shown at 'Bundle.main.loadNibNamed'

I think we are on the same page, I want to create a custom view with IBOutlets. And I want to create it in such a way that it can directly use in storyboard. But it seems to impossible, when init with coder initialise a view, the IBOutlets are nil. If I use a different method using files owner , awake from nib will never execute, here. The sad part is that, the dilemma is to just load a view to screen. Anyone have a comment?
