When you create the custom view with xib and then set the custom view on Storyboard but if It has not appeared. How can you solve the rendering issue?
I stuck in similar issues on Xcode 11.
xcode 11 said -> Failed to render and update auto layout the agent threw an exception
Here is my solution and I hope it helps you!
import UIKit@IBDesignableclass XibView: UIView { let className = String(describing: XibView.self) required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) setupNib() } override init(frame: CGRect) { super.init(frame: frame) setupNib() } private func setupNib() { guard let nib = loadNib() else { return } nib.translatesAutoresizingMaskIntoConstraints = false addSubview(nib) NSLayoutConstraint.activate([ nib.leadingAnchor.constraint(equalTo: self.leadingAnchor), nib.trailingAnchor.constraint(equalTo: self.trailingAnchor), nib.topAnchor.constraint(equalTo: self.topAnchor), nib.bottomAnchor.constraint(equalTo: self.bottomAnchor) ]) } func loadNib() -> UIView? { let bundle = Bundle(for: Self.self) return bundle.loadNibNamed(String(describing: Self.self), owner: self, options: nil)?.first as? UIView }}
