Sure, seems like you are looking for a way to auto search text in your clipboard. So first register clipboard text change listener in this way. Note that it only works within your application:

NotificationCenter.default.addObserver(self, selector: #selector(clipboardChanged),
                                       name: NSNotification.Name.UIPasteboardChanged , object: nil)

Then handle the it by this function

func clipboardChanged(){
    let pasteboardString: String? = UIPasteboard.general.string
    if let theString = pasteboardString {
        print("String is \(theString)")
        // Put the string into your search bar and do the search
    }
}
