Hi, I'm trying to use PencilKit over PDFKit as described in https://developer.apple.com/videos/play/wwdc2022/10089/. The thing is I open my custom UIDocument and initialize all its content to feed PDFView. Everything seems to work, I Input sketches in the canvas, PDFPageOverlayViewProvider's overlayView(for:) generates canvas correctly (it seems) but when editing finishes : willEndDisplayingOverlayView never gets called, and when I save the UIDocument (I use document.close(completionHandler:)) contents(forType:) never sees my custom PDFPages and I get no content for sketches. Does anyone of you have an idea of the lifecycle we should follow to get the methods called ? Sincerely yours

Hello there, I am trying to follow along with the video and copy the example shown here in SwiftUI. I am given the error Cannot assign value of type 'UIView' to type 'PKCanvasView?' on this line: resultView = overlayView It is totally possible that I am botching the whole thing up but I would appreciate it if someone looked over my code. Thanks. code: // ContentView.swift import SwiftUI import PDFKit import PencilKit import Foundation import UIKit struct PDFUIView: View { let pdfDoc: PDFDocument let pdfView: PDFView init() { let url = Bundle.main.url(forResource: "example", withExtension: "pdf")! pdfDoc = PDFDocument(url: url)! pdfView = PDFView() } var body: some View { VStack { PDFKitView(showing: pdfDoc, pdfView: pdfView) } .padding() } } #Preview { PDFUIView() } struct PDFKitView: UIViewRepresentable { let pdfDocument: PDFDocument let pdfView: PDFView init(showing pdfDoc: PDFDocument, pdfView:PDFView) { self.pdfDocument = pdfDoc self.pdfView = pdfView } func makeUIView(context: Context) -> PDFView { pdfView.usePageViewController(true) pdfView.autoScales = true pdfView.pageOverlayViewProvider = context.coordinator pdfView.displayMode = .singlePageContinuous pdfView.isUserInteractionEnabled = true pdfView.document = pdfDocument pdfView.delegate = context.coordinator return pdfView } func updateUIView(_ pdfView: PDFView, context: Context) { pdfView.document = pdfDocument } func makeCoordinator() -> Coordinator { Coordinator() } } class Coordinator: NSObject, PDFPageOverlayViewProvider, PDFViewDelegate { var pageToViewMapping = [PDFPage: UIView]() func pdfView(_ view: PDFView, overlayViewFor page: PDFPage) -> UIView? { var resultView: PKCanvasView? = nil if let overlayView = pageToViewMapping[page] { resultView = overlayView } else { var canvasView = PKCanvasView(frame: .zero) canvasView.drawingPolicy = .anyInput canvasView.tool = PKInkingTool(.pen, color: .systemCyan, width: 20) canvasView.backgroundColor = UIColor.clear pageToViewMapping[page] = canvasView resultView = canvasView } let page = page as!

Hello, We have functionality in an existing app, have to generate a pdf and it should be printable in the A4. The PDF is almost 8 to 10 pages I have applied below solution: Loading the HTML template on the WKwebview and doing a few operations on the content and converting it into a pdf. Converting the HTML into a string Replacing a few data with dynamic content Issue: The solutions worked fine in the previous OS(14.5,15.5,16.1), it is not working on the latest os 16.6 The Table background CSS is not Rendering. I have tried both Inline and external CSS loading but still facing the same issue. Approch1: func createPDF(formmatter: UIViewPrintFormatter, filename: String) -> String { let attributedString = NSAttributedString(string: "This is a test", attributes: [NSAttributedString.Key.foregroundColor: UIColor.red]) let printFormatter = UISimpleTextPrintFormatter(attributedText: attributedString) let render = UIPrintPageRenderer() render.addPrintFormatter(printFormatter, startingAtPageAt: 0) // 2. Assign print formatter to UIPrintPageRenderer //let render = UIPrintPageRenderer() render.addPrintFormatter(formmatter, startingAtPageAt: 0) // 3. Assign paperRect and printableRect let page = CGRect(x: 0, y: 0, width: 595.2, height: 841.8) // A4, 72 dpi let printable = page.insetBy(dx: 20, dy: 20) //let printable = page.inset(by: UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)); render.setValue(NSValue(cgRect: page), forKey: "paperRect") render.setValue(NSValue(cgRect: printable), forKey: "printableRect") // 4. Create PDF context and draw let pdfData = NSMutableData() UIGraphicsBeginPDFContextToData(pdfData, CGRect.zero, nil) for i in 1...render.numberOfPages { UIGraphicsBeginPDFPage(); let bounds = UIGraphicsGetPDFContextBounds() render.drawPage(at: i - 1, in: bounds) } UIGraphicsEndPDFContext(); // 5. Save PDF file var dst = self.getDestinationPath(1) if dst.contains("file://") { dst = dst.replacingOccurrences(of: "file://", with: "") } //let path = "\(NSTemporaryDirectory())\(filename).pdf" pdfData.write(toFile: dst, atomically: true) print("open \(dst)") return dst } } Approach2: But the pdf is Generating in a single page not multiple and it's not printable using the below solution. func createPDFMethod(webView: WKWebView, title:String="samplepdf"){ let pdfConfiguration = WKPDFConfiguration() /// Using `webView.scrollView.frame` allows us to capture the // entire page, not just the visible portion pdfConfiguration.rect = CGRect(x: 0, y: 0, width: webView.scrollView.contentSize.width, height: webView.scrollView.contentSize.height) webView.createPDF(configuration: pdfConfiguration) { result in switch result { case .success(let data): // Creates a path to the downloads directory DispatchQueue.main.async { let resourceDocPath = (FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)).last! as URL let pdfNameFromUrl = "\(title).pdf" let actualPath = resourceDocPath.appendingPathComponent(pdfNameFromUrl) do { try data.write(to: actualPath, options: .atomic) print("pdf successfully saved!") } catch { print("Pdf could not be saved") } } case .failure(let failure): print(failure.localizedDescription) } } } It seems the issue is with UIGraphics or WKwebview formaters. could you please help me to resolve this issue?

I've noticed that edit menu with Copy, Look Up, Translate options doesn't appear when I select some text in pdf file loaded in WKWebView. This issue is reproducible on the latest iOS 16 and 17 beta versions. Additionally, these two WKUIDelegate methods are called for all types of documents except PDFs. func webView(_ webView: WKWebView, willPresentEditMenuWithAnimator animator: UIEditMenuInteractionAnimating) func webView(_ webView: WKWebView, willDismissEditMenuWithAnimator animator: UIEditMenuInteractionAnimating) Is this a bug or is there a new WebKit/PDFKit API I could use to enable this menu?

PDFKit’s characterIndex(at:) method consistently returns the incorrect character index on iOS 17. It seems to get worse the further down the page you get. This breaks critical functionality that my app relies on. Prior to iOS 17, it would be wrong sometimes but not as consistently. This is the method in question: https://developer.apple.com/documentation/pdfkit/pdfpage/1503775-characterindex I've filed feedback FB12951475 with a sample project attached.

PDFKit's PDFPage.characterBounds(at: Int) is returning incorrect coordinates with iOS 17 beta 5 / Xcode 15 beta 6. Worked fine iOS 16 and earlier. It breaks critical functionality that my app relies on. I have filed feedback (FB12918701).

I use PDFView to show PDF files. A PDFView has several editmenu items in advance. Among them, I want to remove the highlight from the item. So, I made PDFView subclass and overrode canPerformAction and buildMenu respectively, but I could not remove the highlight item from the editmenu. If you know how to remove the highlight item, please let me know. Thanks for reading my post.

I have the following code in a prototype application that displays text with a link and presents it in a PDFView. let a4SizePageRect = CGRect(x: 0, y: 0, width: 595.2, height: 841.8) let renderer = UIGraphicsPDFRenderer(bounds: a4SizePageRect) let title = "Some Title Link" let attributedTitle = NSMutableAttributedString(string: title, attributes: [ .font: UIFont.boldSystemFont(ofSize: 24), .link: "<insert here some correct link>", .underlineStyle: NSUnderlineStyle.single.rawValue ]) let data = renderer.pdfData { ctx in ctx.beginPage() attributedTitle.draw(in: a4SizePageRect.insetBy(dx: 25, dy: 25)) } pdfView.document = PDFDocument(data: data) The link only works on iOS 15 versions, but does not work on iOS 16.4 and iOS 17 RC. Based on the documentation for the property and NSAttributedString, the link attribute should still work. Has NSAttributedString stopped supporting NSAttributedString.Key.link in recent versions of iOS?

Hi there, I am currently facing an issue with PDFKit page rendering. In one of my application, I have to open annoted PDF for reading and when user tap on particular annotation, I have to jump certain number of pages in same PDF to open the new desired page. Example: User is on page 2 and when user tap on menu button, I need to navigate directly on page number 8. With above scenario, my application takes a while to load page number 8 and User can see white screen before loading PDF page. When I checked console log, I can see following as an error. F.I: App requires to use usePageViewController for pagination. I am using as per following: _pdfView = [[PDFView alloc] initWithFrame:[UIScreen mainScreen].bounds]; [view addSubview:self.pdfView]; self.pdfView.delegate = self; [self.pdfView setAutoScales:true]; [self.pdfView setDisplayDirection:kPDFDisplayDirectionHorizontal]; [self.pdfView usePageViewController:true withViewOptions:nil]; [self.pdfView setBackgroundColor:UIColor.whiteColor]; Warning: Unable to complete drawing page index 24 on time as a request to forceUpdateActivePageIndex:withMaxDuration: 0.02 I hope if someone can help me on that Thanks.

Hello y'all, I would like to discuss here if anyone else is noticing that some PDF files are not rendered as expected in iOS/iPadOS 17, it seems that some text with background (screenshot attached) are not rendered and you can only see the back color. The issue is reproducible on Preview, Safari, where I guess Apple is using PDFKit framework too. We submitted different issues with Feedback Assistant, however I've not hear back from Apple yet. Is anyone else able to reproduce the issue? Thanks,

I have a 52-page document authored in Pages that contains many equations, most of them pertaining to matrix algebra with many subscripts. Using Pages v13.2 on macOS 14.0 Sonoma (23A344), the exported PDF version of the document does not render the equations correctly. In particular, equations containing a vertical bar "|" are rendered without the vertical bar in the PDF document. For example, an equation for a probability expression of "P(x|y)" gets exported to PDF as "P(x y)". In particular, the Pages "blahtex" form for a discrete-time system equation is \mathbf{x}_{k+1} = \mathbf{\Phi}_{k+1|k} \mathbf{x}_k + \mathbf{u}_k + \mathbf{\Gamma}_{k+1|k} \mathbf{w}_k In Pages, this gets correctly rendered as whereas, in the exported PDF document, it gets incorrectly rendered as Also, using \vert or \mid to generate the "|" in the equation does not help; the PDF export is still missing the "|" symbol. If I save the document in Microsoft Word format and then export to PDF, the equations are rendered correctly. Reverting to Pages v13.1 from Time Machine does not fix the issue; the exported PDF is still wrong. It should be noted that when I used Pages v13.1 in Ventura, exported PDF equations rendered correctly. There may be other formulations that are broken that I have not yet encountered. In addition, my equations in Keynote suffer from the same problem when I export them to PDF. I know that macOS Sonoma removed EPS support, but it looks like other things got broken with this change. I don't want to convert all of my Pages documents to Microsoft Word, but unless this gets fixed, Pages has become useless to me for technical documentation. I'm an engineer with a lot of documents, so this has pretty much brought my workflow to a halt. I've submitted a bug report to Apple (FB13208972), but I am interested if anyone else is experiencing this problem.

Currently I am displaying a pdf in one of my apps using the PDFKit. When I tap on the pdf view there is a strange crash happening related to the the text ranges conversion.

Hi there, I am currently developing an app. I would like to make NavigationLinks from certain words inside an implemented .pdf-file to other Swift view files. Is there a possibility to do this? Here is my code: import PDFKit struct BasismassnahmenPDF: UIViewRepresentable { let pdfDocument: PDFDocument init(showing pdfDoc: PDFDocument) { self.pdfDocument = pdfDoc } func makeUIView(context: Context) -> PDFView { let pdfView = PDFView() pdfView.document = pdfDocument pdfView.autoScales = true return pdfView } func updateUIView(_ pdfView: PDFView, context: Context) { pdfView.document = pdfDocument pdfView.minScaleFactor = 0.6 pdfView.scaleFactor = pdfView.scaleFactorForSizeToFit } } struct Basismassnahmen: View { let pdfDoc: PDFDocument init() { let url = Bundle.main.url(forResource: "Basismassnahmen", withExtension: "pdf")! pdfDoc = PDFDocument(url: url)! } var body: some View { BasismassnahmenPDF(showing: pdfDoc) } } #Preview { Basismassnahmen() } Thank you so much for your help!

The specific pdf when opened in an macOS or web orA Adobe iOS App, it shows the highlighted texts as expected But when opened through any IOS app (except the adobe app) or our native app using pdfkit , the highlights are gone . It disappeared Even the pdf when opened in files app has this issue. Don’t know what’s the problem with the iOS. I have attached the screenshot for the pdf when opened in mac versus the pdf opened in any iOS app. **PDF when opened via Adobe App, ** Pdf when opened via our native app, Raised a feedback regarding this unexpected behaviour . FB Id - FB13326307 Do anyone faced the same issue? Anything am i missing regarding this>

I am refreshing an old app that used the .pageCurl transition allowing user to drop pages in a multipage PDF file like turning the pages in a book. I am committed to using multipage PDF files. I can use UIPageViewController with .pageCurl transition when I am just using multiple UIViews supplied from my DataSource delegate. I cannot see how to use this with a multipage PDF file. I am committed to using SwiftUI and SwiftData which has new app targeting iOS 17. Can anyone point me to some (preferably Apple) example code to do this (that does not involve using non-Apple third party code).

RB24 is my pdf doc. Im using a "view" inside my View Controller and the Class for that view is a PDFView. When I see the pdf on my app, I can't do a search inside the pdf document. How can I achieve that? When you open a pdf in your iPhone, iPhone uses an app that lets you do search and annotations on the pdf. Is there any way to do that for your app ? Any help will be greatly appreciated ! UIKit import PDFKit class ViewControllerRB: UIViewController { @IBOutlet weak var PDFViewRB: PDFView! override func viewDidLoad() { super.viewDidLoad() let url = Bundle.main.url(forResource: "RB24", withExtension: "pdf") if let pdfDocument = PDFDocument(url: url!) { PDFViewRB.autoScales = true PDFViewRB.displayMode = .singlePageContinuous PDFViewRB.displayDirection = .vertical PDFViewRB.document = pdfDocument
