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
@IBDesignable
class 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
}
}
