Hi, in my Extension FilterDataProvider class that is inherited from NEFilterDataProvider i am trying to insert logs into my CoreData entity, but when i insert it gives me error
"NSCocoaErrorDomain: -513
"reason": Unable to write to file opened Readonly
Any suggestions please to update the read write permission
i already have tried this way but no luck
let description = NSPersistentStoreDescription(url: storeURL) description.shouldInferMappingModelAutomatically = true description.shouldMigrateStoreAutomatically = true description.setOption(false as NSNumber, forKey: NSReadOnlyPersistentStoreOption)

On android there is a way for my app to know when the device has been restarted or powered up after a restart or powering off. I wonder if there is a way to listen for the restart/power up even on the iphone and the Apple Watch?

Hi People :)
I'm experimenting with Swift/C++ interoperability these days.
I'd like to understand how could I conform a Swift class to Cxx header:
Like this:
import Application
class App: Application {
public func run() {
let app = NSApplication.shared
let delegate = AppDelegate()
app.delegate = delegate
app.run()
}
}
But I got this error:
/Users/tonygo/oss/native-research/App.swift:27:7: error: inheritance from non-protocol, non-class type 'Application'
class App: Application {
^
ninja: build stopped: subcommand failed.
That seems normal indeed.
Reproductible example: https://github.com/tony-go/native-research/tree/conform-swift-to-cxx-header (Just run make)
I also have another branch on that repo where I use an intermediate Cxx bridge file that conforms to the :Application class and use the Swift API, like this: https://github.com/tony-go/native-research/tree/main/app
Bit I think that its a lot of boilerplate.
So I wonder which approach could I take for this?
Cheers :)

I was following the Swiftui tutorial at section 6 (https://developer.apple.com/tutorials/swiftui/creating-and-combining-views) to use a circle image to create an overlapping effect on the map. Turns out that when using a GeometryReader, the bottom padding was not working at all:
VStack{
MapView().frame(height:300)
CircleImage()
.offset(y: -130)
.padding(.bottom, -130)
VStack(alignment:.leading){
Text(
"Turtle Rock"
)
.font(
.title
)
HStack {
Text(
"Joshua Tree National Park"
)
.font(
.subheadline
)
Spacer()
Text(
"California"
)
.font(
.subheadline
)
}
}.padding(/*@START_MENU_TOKEN@*/10/*@END_MENU_TOKEN@*/)
}
This is the code for the CicleImage view: GeometryReader(content: { geometry in
let _ = print(
geometry.size.width
)
AsyncImage(
url: URL(
string: "https://cms.rationalcdn.com/v3/assets/blteecf9626d9a38b03/bltf5486c52361f2012/6144fafd39dff133fc23de9f/img-ios.png"
)
)
.frame(width: geometry.size.width)
.clipShape(
Circle()
).overlay{
Circle().stroke(
.white,
lineWidth: 4
)
}.shadow(
radius: 7
)
})
I just purchased a new M3 chip MacBook Air a little after it came out. I was able to create and deploy an iOS application. However, now that I am trying to create a new project Xcode throws an error upon launch.
Steps to recreate the error (if possible)
Open Xcode
Select create new app
An error is where the preview should be.
At this point I have added no code. It is all boiler plate from Apple.

Hello. I've been looking all over this forum and stack and done some internet searches but unfortunately have found nothing to assist in fixing an error I'm receiving on my project in Xcode.
Every view shows an error identical to the one shown above, only with that specific file name displayed instead. When I go to fix the error, this is the error detail displayed:
== PREVIEW UPDATE ERROR:
LinkDylibError: Failed to build TabBar.swift
Linking failed: linker command failed with exit code 1 (use -v to see invocation)
ld: warning: search path '/Applications/Xcode.app/Contents/SharedFrameworks-iphonesimulator' not found
ld: unsupported mach-o filetype (only MH_OBJECT and MH_DYLIB can be linked) in '/Users/brycemchose/Library/Developer/Xcode/DerivedData/Service_Square_App-dnblqgabcrxprhaizjtkcvouyzln/Build/Intermediates.noindex/Previews/iphonesimulator/Service Square App/Products/Debug-iphonesimulator/Service Square.app/Service Square'
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Note that I can run the app successfully to a simulator or to my iPhone, but cannot see the preview within the Xcode canvas. I've been blindly developing the last two app updates, pushing the changes to the simulator and then tweaking the code based on the simulated version. I can keep doing this for a little while but it is significantly slower and more difficult, especially to fix small bugs and make tiny changes, so I'd really like to see if anyone has an idea for how I can get the preview back to being properly displayed. I'm brand new to this whole thing and have no idea how to fix this issue, so I'd be really grateful if someone with more experience could offer some suggestions! Thanks in advance! :)
I'm writing a SpriteKit game in Swift that does this familiar dance in my GameScene touchesEnded(...)...
let touch = touches.first!.location(in: self)
let nodes = self.nodes(at: touch)
...but sometimes when the game is running, the nodes collection is empty, even though there are clearly, visibly nodes under the touch. All of the nodes I care about are children of a single SKNode, MapNode, that is one of two children of the GameScene.
After a bunch of debugging, I've noticed that when this problem happens, something is causing calculateAccumulatedFrame() to return a frame that is way, way smaller than the real bounds of MapNode.
When the scene begins, calculateAccumulatedFrame() is perfect, but something that happens later on breaks it. I've tried adding a node to MapNode that is the correct size to 'force' calculateAccumulatedFrame to do the right thing, but this doesn't work.
Is there something obvious I am doing wrong, or some common pitfalls? Is there some way to force calculateAccumulatedFrame to return this correct size?

Hi,
Using iOS 17.2 trying to build an ios app with Content Filter Network extension.
My problem is that when I build it on a device and go to Settings --> VNP & Device Management the Content Filter with my identifier is showing BUT is shows invalid.
Appname is Privacy Monitor and Extension name is Social Filter Control
Here is is my code
`//
// PrivacyMonitorApp.swift
import SwiftUI
@main
struct PrivacyMonitorApp: App {
@UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
import NetworkExtension
class AppDelegate: UIResponder, UIApplicationDelegate {
static private(set) var instance: AppDelegate! = nil
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
configureNetworkFilter()
return true
}
func configureNetworkFilter() {
let manager = NEFilterManager.shared()
manager.loadFromPreferences { error in
if let error = error {
print("Error loading preferences: \(error.localizedDescription)")
return
}
// Assume configuration is absent or needs update
if manager.providerConfiguration == nil {
let newConfiguration = NEFilterProviderConfiguration()
newConfiguration.filterBrowsers = true
newConfiguration.filterSockets = true
// newConfiguration.vendorConfiguration = ["someKey": "someValue"]
manager.providerConfiguration = newConfiguration
}
manager.saveToPreferences { error in
if let error = error {
print("Error saving preferences: \(error.localizedDescription)")
} else {
print("Filter is configured, prompt user to enable it in Settings.")
}
}
}
}
}
Next the FilterManager.swift
`import NetworkExtension
class FilterManager {
static let shared = FilterManager()
init() {
NEFilterManager.shared().loadFromPreferences { error in
if let error = error {
print("Failed to load filter preferences: \(error.localizedDescription)")
return
}
print("Filter preferences loaded successfully.")
self.setupAndSaveFilterConfiguration()
}
}
private func setupAndSaveFilterConfiguration() {
let filterManager = NEFilterManager.shared()
let configuration = NEFilterProviderConfiguration()
configuration.username = "MyConfiguration"
configuration.organization = "SealdApps"
configuration.filterBrowsers = true
configuration.filterSockets = true
filterManager.providerConfiguration = configuration
filterManager.saveToPreferences { error in
if let error = error {
print("Failed to save filter preferences: \(error.localizedDescription)")
} else {
print("Filter configuration saved successfully. Please enable the filter in Settings.")
}
}
}
}
Next The PrivacyMonitor.entitlements
`
The Network Extension capabilties are on and this is the SocialFilterControl
`import NetworkExtension
class FilterControlProvider: NEFilterControlProvider {
override func startFilter(completionHandler: @escaping (Error?) -> Void) {
// Initialize the filter, setup any necessary resources
print("Filter started.")
completionHandler(nil)
}
override func stopFilter(with reason: NEProviderStopReason, completionHandler: @escaping () -> Void) {
// Clean up filter resources
print("Filter stopped.")
completionHandler()
}
override func handleNewFlow(_ flow: NEFilterFlow, completionHandler: @escaping (NEFilterControlVerdict) -> Void) {
// Determine if the flow should be dropped or allowed, potentially downloading new rules if required
if let browserFlow = flow as? NEFilterBrowserFlow,
let url = browserFlow.url,
let hostname = browserFlow.url?.host {
print("Handling new browser flow for URL: \(url.absoluteString)")
if shouldBlockDomain(hostname) {
print("Blocking access to \(hostname)")
completionHandler(.drop(withUpdateRules: false)) // No rule update needed immediately
} else {
completionHandler(.allow(withUpdateRules: false))
}
} else {
// Allow other types of flows, or add additional handling for other protocols
completionHandler(.allow(withUpdateRules: false))
}
}
// Example function to determine if a domain should be blocked
private func shouldBlockDomain(_ domain: String) -> Bool {
// Add logic here to check the domain against a list of blocked domains
let blockedDomains = ["google.com", "nu.nl"]
return blockedDomains.contains(where: domain.lowercased().contains)
}
}
And it's info.plist
`
and the entitlements file
`
In Xcode using automatically manage signing and both targets have the same Team

Hello, i am trying to record logs in my network extension class, and then i want to read it in my application class, i.e. viewModel. However, i am unable to read the data. I have tried different ways like UserDefaults, Keychain, FileManager, NotificationCenter and CoreData. I have also used Appgroups but still there is blocker for reading data outside the scope of Extension class.

Hello everyone!
I'm currently working on an iOS app developed with Swift that involves connecting to a specific bluetooth device and exchanging data even when the app is terminated or running in the background.
I just want to understand why the CBCenterManager should be Implicitly unwrapped to use it. I have check out couple off apple developer sample project it was set to Implicitly unwrapped. can some one help to understand the reason behind this, also what are possible issues/scenario trigger if we set the centermanager to optional "CBcentermanager?"
Thanks in Advance!

Hi everyone!
We are wondering whether it's possible to have two macOS apps use the Voice Processing from Audio Engine at the same time, since we have had issues trying to do so. Specifically, our app seems to cut off the input stream from the other, only if it has Voice Processing enabled. We are developing a macOS app that records microphone input simultaneously with videoconference apps like Zoom.
We are utilizing the Voice Processing from Audio Engine like in this sample: https://developer.apple.com/documentation/avfaudio/audio_engine/audio_units/using_voice_processing
We have also noticed this behaviour in Safari recording audios with the Javascript Web Audio API, which also seems to use Voice Processing under the hood due to the Echo Cancellation.
Any leads on this would be greatly appreciated!
Thanks

I have my app already in live before the privacy manifest introduced. Now, I want to migrate from cocoapods to Swift Package Manager. Will this be considered like adding the third party SDKs as new ones or will it be considered existing ones? So far I have not received any emails from Apple regarding the privacy manifest. I do not want any issues with the privacy manifest.

Is the timeout for session-level authentication challenge handling documented somewhere? For example, if I get the urlSession(_:didReceive:) callback for server trust authentication, how long do I have to invoke the completion handler (or return from the callback if using Swift Concurrency)?
Or is this completely dependent on the server's settings?

I have a container view implementation that reads preference values from child views:
public struct Reader<Content>: View where Content: View {
public var content: () -> Content
public init(@ViewBuilder content: @escaping () -> Content) {
self.content = content
}
public var body: some View {
content()
.onPreferenceChange(NumericPreferenceKey.self) { value in
// ...
}
}
}
This works fine until the content passed in to the container view is a Group. At that point the onPreferenceChanged modifier is applied to every child of the group, which leads to bugs in my situation.
One thing I can do is simply put the content in a VStack:
public var body: some View {
VStack(content: content)
.onPreferenceChange(NumericPreferenceKey.self) { value in
// ...
}
}
And that works fine to "Ungroup" before applying the onPreferenceChanged modifier. However, is this best practice? Is there a better way to apply a modifier to content as a whole instead of to each member of a potential group? Is it concerning that I might have an extra VStack in the view hierarchy with this fix?

How can we cast video, Images, Screen Mirroring from iOS to Smart TV Device(Apple, Android or etc.) i am using GoogleCast SDK iOS but it's cast only server URL video.
Is there any SDK or code for cast video and Images.
On my shop and content views of my app, I have a shopping cart SF symbol that I've modified with a conditional to show the number of items in the cart if the number of items is above zero. However, whenever I change tabs and back again, that icon disappears even though there should be an item in the cart.
I have a video of the error, but I have no idea how to post it. Here is some of the code, let me know if you need to see more of it:

return numberofproducts
}
func addToCart(product: Product) {
products.append(product)
total += product.price
numberofproducts = products.count

I am getting this error, only in iOS 17 (all version) on old code that had been working since iOS 15. The error occurs whenever the collectionView need to increase it's height beyond its initial height. The collectionView is inside a tableView. All autolayout constraints are set and everything use to work fine in previous version of iOS.
