CodePudding user response：

Conform your view controller to UITextPasteDelegate:

class viewController: UIViewController, UITextPasteDelegate { ...

And set past delagete:

textView.pasteDelegate = self

Then implement textPasteConfigurationSupporting function:

func textPasteConfigurationSupporting(
    _ textPasteConfigurationSupporting: UITextPasteConfigurationSupporting,
    performPasteOf attributedString: NSAttributedString,
    to textRange: UITextRange) 
-> UITextRange {
    <#code#>
}
