How to make PDFView Created in func makeUIView(context: UIViewRepresentableContext<PDFDisplayRepresentedView>) -> PDFView Available in the view displaying the pdf so I can access its properties to obtain page number. import SwiftUI import PDFKit struct PDFDisplayView: View { @Binding var pdfDocument : PDFDocument? var body: some View { PDFDisplayRepresentedView(pdfDocument: pdfDocument!) } } struct PDFDisplayRepresentedView: UIViewRepresentable { let pdfDocument: PDFDocument init(pdfDocument: PDFDocument) { self.pdfDocument = pdfDocument } func makeUIView(context: UIViewRepresentableContext<PDFDisplayRepresentedView>) -> PDFView { return createPDFViewUsing(document: pdfDocument) } func updateUIView(_ pdfView: PDFView, context: UIViewRepresentableContext<PDFDisplayRepresentedView>) { pdfView.document = pdfDocument } private func createPDFViewUsing(document : PDFDocument) -> PDFView { let pdfView = PDFView(frame: CGRect(x: 0, y: 0, width: 100, height: 100)) pdfView.document = document ... set up pdfView attributes return pdfView } } view showing pdf where I want to know the page number pseudo code … @State private var pdfDisplayView : PDFDisplayView? …. var body: some View { load the pdf into this view. need to access the page number pdfDisplayView }

As I sit here on the fourth hour waiting for Xcode to install. Can’t help, but think it would be nice if there was a way for notifications to be sent to my phone when applications on my computer have finished downloading, or installing

Not developer related but I can't find any help with google and trying to send a crash report to apple just causes spinning beachball. So hoping i can find some much needed help in this forum. Safari runs very slow and every time it launches i get an error producing the log below. Any fix suggestions please. Seeing a WebPrivacy library missing leaves me with no confidence using my mac. I had hoped a software update to Ventura 13.6.3 would resolve but no.

I would like to move my external beta testers to another one of my apps. Is this possible or do I have to manually enter each one again manually as a tester for my other apps?

@Model class modelData { var property1 : String = "" init(property1: string){ ... } } for item in arrayOfManyStrings { let instanceOfModelData = modelData(property1: item) } Trying to create multiple instances of my modelData. I expect the loop to run and create instanceOfModelData 30k times. However it is far too slow. 30-90 seconds depending on device. If I remove the @Model macro, the same loop take < 5 seconds. I obviously need the @Model for swiftData. How to speed up creating instances of instanceOfModelData when using @Model

Im trying to duplicate the display of the built in Files app for documents in my app. How do I convert a page in a PDFDocument to an Image to display as an icon like seen here (from Files App) with SwiftUI. SOLVED: Image(uiImage: (document.page(at: 0)?.thumbnail(of: CGSize(width: 100, height: 100), for: .cropBox))!)

if I get the string contents of a PDF and print to the console in Xcode . when run on simulator it’s fine but on device some words are missing. same PDF, same code. only difference is simulator and physical device. its only a word or two missing from the page. anyone have any experience or suggestions with PDFKit to explain why a string would be missing the odd word ?

I know if i change existing properties in a @Model it’s a migration. However if I add a new @Model class(es) that has no relationships to any existing is that still a migration or am i free to add? if free to add, should i create a new model container or can I just add the new Model classes ?

From the Internet I read that URLRequest sends an Accept-Encoding header by default. I also read that URLSession auto decompresses any data that’s returned compressed. However these are what the internet says. I go to the Apple docs and read the URLSession &amp; URLRequest sections but I can’t find where does it say that it sends the Accept-Encoding headers by default or that it auto decompresses compressed data. I know it does the latter as I am able to parse compressed data and have to do nothing to decompress. Just tell me where this stuff is documented by Apple so I can read about it.

I use UIHostingController inside my UIViewController to present a SwiftUI View. I have a button in that view which I want to tap and dismiss the presented view. How do I dimiss SwiftUI views when presented in a UIHostingController...{ let vc = UIHostingController(rootView: SwiftUIView()) present(vc, animated: true, completion: nil) }struct SwiftUIView : View { var body: some View { CustomButton() } }struct CustomButton: View { var body: some View { Button(action: { self.buttonAction() }) { Text(buttonTitle) } } func buttonAction(){ //dismiss the SwiftUIView when this button pressed } }

With NSFetchRequest of coreData it was possible to only return distinct results from the database with .returnsDistinctResults What if any is the fetch equivalent in SwiftData ? currently I'm appending entries into a Set<String>. Only with over 200k rows and no newBackgroundContext() in SwiftData the UI is locked for a number of seconds

My database has over 100k entries and anytime I access it either via @Query or a custom Fetch request it freezes my apps UI for 10+ second. My first question is anyone having performance issues with large data sets. If so how have you found to resolve it ? My next question is does swiftUI load the entire database into memory with the @Query. As I feel it is seeing as my app becomes very slow and partially unresponsive. lastly if I have 2 data models and 1 has a to many relationship to the other are both loaded into memory even though only @Query 1? consider datamodels model1 { var name : String @Relationship(deleteRule:.cascade) var lotsOfData :[LotsOfData] init.... } LotsOfData{ var element1 : String var element2 : String var element3 : String var element4 : String var element4 : String init …. } LotsOfData has 100K instances in the database. if I @Query into model1 because it references LotsOfData through A relationship is all that data all called / loaded ? thanks for the information

How often/ under what circumstances are users sandbox directory URL's changed? So I tried to save a URL to a document in @AppStorage @AppStorage(DefaultsKey.userActiveBook.rawValue) var activeBook : URL = Bundle.main.url(forResource: "BookPlaceHolder", withExtension: "pdf")! When user selects a new document activeBook is updated with the new URL. Issue is when the app relaunches from xCode the path to whatever is stored in activeBook changes. My work around so far is to just access the users Documents Directory via FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!. Then appending the last path component of activeBook. sidebar: obviously this doesn't work if the saved URL in activeBook is still the default from Bundle.main.url. I haven't written that workaround as yet. Am I only seeing issues in development due to a fresh relaunch via xCode? If the user only ever terminates the app on their device are the .documentDirectory URL's changing on each launch or do the remain constant? I don't want to write a workaround to ensure the correct URL for whats stored in @AppStorage, if the changing URL's only occurs due to launching from xCode which the end user wont ever encounter that edge case.

Submitted a TSI 4 days ago. Heard nothing back. Status Used. Surely a TSI is a fulfilled request and not just ignored? Also the forum tags don't have TSI so not sure where this post will end up
