you need to add this line of code:

pdfView.usePageViewController(true, withViewOptions: nil)

****UPDATE**

PDFDocument . has some notifications about search. Have a look.

try this code for searching string.in this line beginFindString you can set string

var searchedString: PDFSelection?
override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
        self.document?.beginFindString("StringName", withOptions: .caseInsensitive)        
}

func documentDidEndDocumentFind(_ notification: Notification) {
    pdfView.setCurrentSelection(searchedString, animate: true)
}

func documentDidFindMatch(_ notification: Notification) {
    if let selection = notification.userInfo?.first?.value as? PDFSelection {
        selection.color = .Red
        if searchedString == nil {
            // The first found item sets the object.
            searchedString = selection
        } else {
            // All other found selection will be nested
            searchedString!.add(selection)
        }
    }
}
