A SwiftUI wrapper for UIView that provides protection against screenshots. This view uses a UITextField with isSecureTextEntry set to true to create an invisible, screenshot-proof container in which you can place other views.

SecureView.swift

public struct SecureView<Content: View>: UIViewRepresentable {
  let content: () -> Content
  
  public init(@ViewBuilder content: @escaping () -> Content) {
    self.content = content
  }
  
  public func makeUIView(context: Context) -> UIView {
    let secureTextField = UITextField()
    secureTextField.isSecureTextEntry = true
    secureTextField.isUserInteractionEnabled = false
    
    guard let secureView = secureTextField.layer.sublayers?.first?.delegate as? UIView else {
      return UIView()
    }
    
    secureView.subviews.forEach { subview in
      subview.removeFromSuperview()
    }
    
    let contentHostingController = UIHostingController(rootView: content())
    contentHostingController.view.backgroundColor = .clear
    contentHostingController.view.translatesAutoresizingMaskIntoConstraints = false
    
    secureView.addSubview(contentHostingController.view)
    NSLayoutConstraint.activate([
      contentHostingController.view.topAnchor.constraint(equalTo: secureView.topAnchor),
      contentHostingController.view.bottomAnchor.constraint(equalTo: secureView.bottomAnchor),
      contentHostingController.view.leadingAnchor.constraint(equalTo: secureView.leadingAnchor),
      contentHostingController.view.trailingAnchor.constraint(equalTo: secureView.trailingAnchor)
    ])
    
    return secureView
  }
  
  public func updateUIView(_ uiView: UIView, context: Context) {}
