User Profile

So here is the problem. I have created a custom loader which shows a basic "loading" text in the middle with dimmed background. The HUD shows just fine but despite of setting isUserInteractionEnabled to false I still can click on the UI where I have added the HUD. Here is the code: public class Loader { public static let shared = Loader() private(set) var containerView = UIView() private(set) var lblText = UILabel() private init() { self.containerView.frame = UIScreen.main.bounds self.containerView.backgroundColor = UIColor(red: 0/255, green: 0/255, blue: 0/255, alpha: 0.5) self.containerView.isUserInteractionEnabled = false lblText.font = UIFont.boldSystemFont(ofSize: 30) lblText.textAlignment = .center lblText.textColor = .white lblText.text = "Loading..." containerView.addSubview(lblText) lblText.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint(item: lblText, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: containerView, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0).isActive = true NSLayoutConstraint(item: lblText, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: containerView, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0).isActive = true NSLayoutConstraint(item: lblText, attribute: NSLayoutConstraint.Attribute.width, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 275).isActive = true lblText.heightAnchor.constraint(equalTo: lblText.widthAnchor, multiplier: 181/375).isActive = true } public func show() { DispatchQueue.main.async( execute: { if let found = UIApplication.key?.subviews.contains(where: {$0 == self.containerView}), found { self.containerView.superview?.bringSubviewToFront(self.containerView) } else { UIApplication.key?.addSubview(self.containerView) } }) } @objc public func hide() { DispatchQueue.main.async( execute: { self.containerView.removeFromSuperview() }) } } extension UIApplication { static var key: UIWindow? { if #available(iOS 13, *) { return UIApplication.shared.connectedScenes .filter({$0.activationState == .foregroundActive}) .map({$0 as? UIWindowScene}) .compactMap({$0}) .first?.windows .filter({$0.isKeyWindow}).first } else { // do lower version specific window setup return UIApplication.shared.keyWindow } } } Usage: Loader.shared.show() and Loader.shared.hide() Whats wrong with the code?
