renderer.writePDF doesn't work without error

Question

I learn swift and faced with problem: when i try write pdf file in document directory nothing happened. Code:

func createPDF() {
        // MARK: - create path
        let documentDir = FileManager.default.urls(for: .cachesDirectory, in: .userDomainMask).first!
        let path = documentDir.appendingPathComponent("\(clientCompanyName + UUID().uuidString).pdf")

        // MARK: - create meta
        let pdfMetaData = [
            kCGPDFContextCreator: "something",
            kCGPDFContextAuthor: "https://bla-bla.com"
        ]
        let format = UIGraphicsPDFRendererFormat()
        format.documentInfo = pdfMetaData as [String: Any]
        
        // MARK: - set page size
        let pageWidth = 8.5 * 72.0
        let pageHeight = 11 * 72.0
        let pageRect = CGRect(x: 0, y: 0, width: pageWidth, height: pageHeight)
        
        // MARK: - render
        let renderer = UIGraphicsPDFRenderer(bounds: pageRect, format: format)
        try? renderer.writePDF(to: path) { (context) in
            let attributes = [
                NSAttributedString.Key.font: UIFont.boldSystemFont(ofSize: 72)
            ]
            let text = clientCompanyName + " " + formattedDate
            text.draw(at: CGPoint(x: 0, y: 0), withAttributes: attributes)
        }
    }

When i start this code, i don't see any errors in terminal. But if i open Files, my document didn't save
