Edit:
having found a solution for issue 2 (and kind of getting the impression that there is no easy, out of the box solution for issue 1) I decided to close this question and rather create another one some time specifically for the pagination problem.
I have two issues with WKWebViews createPDF(configuration:completionHandler:):
- no pagination (I know that this issue has been brought up by others and that there seemingly is no automatic solution to this – I guess paginating would be a manual endeavour…)
- the html I load seems to be replacing spaces with new lines
The following code…
import SwiftUI
import WebKit
@main
struct PdfCreatorSOApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
struct ContentView: View {
var body: some View {
Button("Create PDF") {
savePdf()
}
.padding()
}
private func savePdf() {
if let downloadDir = FileManager.default.urls(for: .downloadsDirectory, in: .userDomainMask).first {
let savePath = downloadDir.appendingPathComponent("swiftPdf").appendingPathExtension("pdf")
let webViewConfiguration = WKWebViewConfiguration()//do I need to set s.th. here?
let webView = WKWebView(frame: .zero, configuration: webViewConfiguration)
let pdfConfiguration = WKPDFConfiguration()
pdfConfiguration.rect = CGRect(x: 0, y: 0, width: 595.28, height: 841.89)
webView.loadHTMLString(html, baseURL: nil)
DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
webView.createPDF(configuration: pdfConfiguration) { result in
switch result {
case .success(let data):
do {
try data.write(to: savePath)
print("Successfully created and saved pdf…")
} catch let error {
print("Could not _save_ pdf: \(error)")
}
case .failure(let error):
print("Could not create pdf: \(error)")
}
}
}
}
}
}
let html = """
<html>
<body>

…produces this output:
Is there something missing in my WKWebViewConfiguration()?
