Using PDFKit to Open PDF in App Automatically after Downloading - swift

Question

Missing some connection which I am unable to figure out (also googled a lot still no success) in how to open PDF file in app. I am using PDFKit. This is the PDFKitView struct in which URL should be passed:
struct PDFKitView: View {
#State var reportId: ReportResponse
var url:URL
var body:some View
{
PDFKitRepresentedView(url)
}
}
struct PDFKitRepresentedView: UIViewRepresentable{
func updateUIView(_ uiView: UIView, context:
UIViewRepresentableContext<PDFKitRepresentedView>) {
//
}
let url: URL
init(_ url:URL)
{
self.url = url
}
func makeUIView(context: UIViewRepresentableContext<PDFKitRepresentedView>) ->
PDFKitRepresentedView.UIViewType {
let pdfView = PDFView()
pdfView.document = PDFDocument(url: self.url)
pdfView.autoScales = true
return pdfView
}
}
This is the Report Row in which I am trying to pass URL to state object pdfDonwload:
struct ReportRow: View {
var report : ReportResponse
#StateObject var pdfDownload:URL = URL(fileURLWithPath: "")
var body: some View {
VStack{
HStack{
Text(report.name)
//formatting
}.frame(maxWidth: .infinity, alignment: .leading)
HStack{
Text("P.Id:")
//formatting
Text(report.patientID)
//formatting
Spacer()
Text("Status")
//formatting
Text(report.status)
//formatting
}}
.onAppear{
Task{
do{
try await getPath()
}catch{Alert(title:"Text")}
}
}}
func getPath() async throws
{
var urlComponents = URLComponents()
//add other components
urlComponents.queryItems = [URLQueryItem(name:
"uniquePackageId", value:
uniqueReportId)]
let url = urlComponents.url
let downloadTask = URLSession.shared.downloadTask(with: url!)
{
urlOrNil, responseOrNil, errorOrNil in
guard let fileURL = urlOrNil else {return}
do
{
let documentURL = try FileManager.default.url(for:
.documentDirectory, in:
.userDomainMask, appropriateFor: nil, create: false)
let savedURL = documentURL.appendingPathComponent("\
(self.patientName)_\(UUID().uuidString).pdf")
print(savedURL)
try FileManager.default.moveItem(at: fileURL, to:
savedURL)
DispatchQueue.main.async {
pdfDownload = url!
}
}
catch
{
print("Error")
}}
downloadTask.resume()
}}
However, no value is passed to PDFKitView() it is blank. The first issue is PDFKitView should get the updated pdfDownload:URL value from the func call. Neither the value is updating nor passing updated value to PDFKitView.
This is the list struct:
struct ReportList: View{
#ObserveObjecct var reportLink:ReportViewModel
#State var pdfDownload:URL = URL(fileURLWithPath="")
var body:some view{
NavigationView{
List{
ForEach(reportLink.trackReport)
{report in
VStack{NavigationLink
(destination:PDFKitView(url:pdfDownload,
pdfDownload:pdfDownload,report:report))
{
ReportRow(report:report)
}
}}}}}}
I want file should open automatically after downloading. Running the app in simulator.
