    print(pdfDocument.isEncrypted, pdfDocument.isLocked) // true, true
                            
    if let pdfDocument = PDFDocument(url: url) {
        if pdfDocument.isEncrypted {
            if pdfDocument.unlock(withPassword: password) {
                print(pdfDocument.isEncrypted, pdfDocument.isLocked) //true , false

        }
    }

As the documentation explains, your result is expected and correct:

 isEncrypted: Bool { get }

true if the document is encrypted, whether it is locked or unlocked; false otherwise.

(My italics.) So don't worry, be happy.
