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.

So I am trying to sync only some of my Models with iCloud and others kept locally in the default.store. I am having a world of issues so before I start looking for the needle in my haystack. I would like to ask this forum, is my approach one that should work as desired or is my code obviously why things are not working? All my Models have default values and relationships where needed are optionals. iCloud is working but my issue arises when i try to exclude some models. So I want to sync "modelsForCloudSyncing" but not "modelNotForCloudSyncing" In advance thank you
var avoidCloudSyncModelContainer : ModelContainer = {
let modelNotForCloudSyncing = Schema([NoCloudSyncModel.self])
let modelConfigForNoCloudSync = ModelConfiguration(schema: modelNotForCloudSyncing, cloudKitDatabase: .none)
let modelsForCloudSyncing = Schema([CloudSyncModelA.self, CloudSyncModelB.self, CloudSyncModelC.self])
let modelConfigForCloudSync = ModelConfiguration(schema: modelsForCloudSyncing, cloudKitDatabase: .automatic)
do {
return try ModelContainer(for: NoCloudSyncModel.self, CloudSyncModelA.self, CloudSyncModelB.self, CloudSyncModelC.self, configurations: modelConfigForNoCloudSync, modelConfigForCloudSync)
}
catch { fatalError("Could not create ModelContainer: \(error)") }
}()
...
{
ContentView()
}.modelContainer(avoidCloudSyncModelContainer)

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 have a loop that iterates all pages in a PDF and saves parts of its content into core data. Problem seems to be that each PDFPage takes up around 30mb+ of memory. This memory is not retuned when the loop moves to ther next page. with large enough PDF in can cause out of memory crash.At first I thought it was something in the loop holidng a reference. However when I dont run the loop, or attempt to save any of the PDFPage contents and simply swipe through the PDFPages of the PDF, the memory still goes up 30mb + per page. So my question is how to clear the previous page from memory when no longer the page in view?I would add code but seems you cant pste into here so jist know its basic PDFKit code to load a pdf url

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
cant see where to delete posts
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

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

I create a UIViewRepresentable to show my PDF inside my SwiftUI app. I want to access the current page number using currentPage?.pageRef?.pageNumber. from the view in which I display the pdf. 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

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 & 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.

Big Sur Beta 5 won't install for me or many others it seems. I'm on a 2017 iMac 5k. The iOS 14 betas have been absolutely terrible and my 3rd gen Apple Watch claims I have to delete files in order to install the latest beta on that. I have 0 songs, 15 phantom photos (no idea how to get rid of those) and just 6 apps. The update needs 2.9GB of space and despite having nothing on the watch really I only have 2.7GB free. There is no way for me to even clear some more space.
I wouldn't mind or complain if I wasn't paying apple $99 to be a developer. Not to mention the thousands of $$ paid for the hardware. The very minimum we deserve is these betas are actually able to be installed.

In iOS when a button can be actioned it is coloured accordingly so the user knows to tap. This is a standard across the platform. Is there a standard for long press gestures? In the case of swiftUI the 3D Touch/ long press can show a contextMenu. How best to indicate to a user to long press? Is there a standard colour for example to show when an element is to be long pressed?

Since iOS 13 (including all recent betas) if a PDF page should have a background colour that colour isn’t showing and instead the page is white. I’m displaying the page with the PDFKit framework. I’ve also noticed that this is occurring in Apples own apps too like iBooks so no point posting code as it’s not my code specific. I’ve also noticed this only seems to happen for some users so appears to be either device specific or some other attribute. Has anyone here found this and indeed a solution ?
