Hello and thanks for reading my post.
I have a SwiftUI view, the users should be able to click a button and take printout of that view. Clicking on the button should open the standard print sheet (select printer, pages, layout, etc.).
How can I implement such a functionality? I have been trying hard without any success. Please help.
It is an iPad app, using Xcode 14.3
I do it a bit differently.
Instead of calling directly the printer, I copy the view in the pasteboard. And I can then put in in any app (mail, preview…) and print if needed.
It is effectively a multi step process, but it provides interesting flexibility.

Hope that helps.
I showed for text, but it works as well for a complete view with subviews. Same principle, just change copyToClipboard:
func copyToClipboard() {
if let image = ViewForPaste() // The View to print
.snapshot()?.png {
pasteboard.declareTypes([NSPasteboard.PasteboardType.png], owner: nil)
pasteboard.setData(image, forType: .png)
}
}
But as I said, it is not the direct print you looked for.
For it, you need to use NSPrintOperation.
To print directly, have a look here on how to print an image:
then, use the snapshot created for the pasteborad
Claude31. did you ever get this to work? I followed devlabs and got the text to print they showed but am having same issue as you. printing a portion of my screen.
Got it working. I wrapped my SwiftUI View to be printed(and displayed) in a local function like this:
private func generateView() -> some View {
VStack { .... }
}
Then I created a func to save the some View as a PDF in the document directory using ImageRenderer. The func also returns the PDF's URL which was created using URL.documentsDirectory.appending(path:)
Then I created another func using UIPrintInteractionController and the PDF's URL to present the print controller for the saved pdf.
