Does the iPhone or iPad support reception of the following communication standards?
If so, please let me know if there is an swift API available.
・Bluetooth 5.x Long Range
・Wi-Fi Neighbor Awareness Networking (Wi-Fi Aware)
・Wi-Fi Beacon
Hello,
When an iOS app runs on Vision Pro in compatible mode, is there a flag such as isiOSAppOnVision to determine the underlying OS at runtime? Just like the ProcessInfo.isiOSAppOnMac. It will be useful to optimize the app for visionOS.
Already checked but not useful:
#if os(xrOS) does not work in compatible mode since no code is recompiled.
UIDevice.userInterfaceIdiom returns .pad instead of .reality.
Thanks.

fetchPartialContents(for:version:request:minimalRange:aligningTo:options:completionHandler:)
I need to use this function to fetch contents of the files partially. But it seems I'm just unable to receive any callback when i try to open the file via double click on finder.
I've tried to open files of different types and sizes but still i'm defaulting back to fetchContents(for:version:request:completionHandler:) .
I've been thinking if there are any specific configurations or requirements that i have to meet , so i could trigger this callback function for all the fetch Operations for files ?
If No, then where am i going wrong ?
We want to keep our Mac UI app running all the time, when a user is logged into to a mac machine (app resides in /Applications). To achieve this, we can use launchctl from within post-isntall script to load a plist file which resides in /Library/LaunchAgent.
How to prevent a user (without admin password) to unload the agent using launchctl from terminal?
I'm trying to put a sub menu inside the context menu using the NSExtensionFileProviderActions in info.plist. Which should look like this image below
I have been trying to use FPUIActionExtensionViewController for doing this task but I havent got any context menu like above. But still doing that does seem to complicate the task more.
Is there a simpler way to do this task, like doing it within the info.plist so I dont have to complicate the task by creating a view controller. ?
Hi there!
Sorry in advance, this is going to be a long post of Apple developer pains which I want to share with you, and, hopefully, find the answer and help Apple become better.
I'm at the very beginning of my new and exciting personal project which (I hope) may one day feed me and be my daily source of inspiration. I'm not a newbie in Apple development nor am I a senior-level developer — just a fellow developa'.
Here's the problem I bring to you — why Apple promotes Unified Logging System and recommends using it as the primary way to implement logging in 3rd-party apps? No doubt, OSLog is a great, secure, efficient, and centralized way to gather diagnostics information, and I, starting my new project, am itching to choose exactly this 1st-party logging infrastructure. This decision in theory has a number of benefits:
I don't have to depend on 3rd-party logging frameworks which may eventually be discontinued;
I have extensive documentation, great WWDC sessions explaining how to use the framework, and stackoverflow answers from the whole Apple dev community in case I experience any troubles;
I have this cool Console.app and upcoming Xcode 15 tools with great visualization and filtering of my logs;
It's quite a robust and stable infrastructure which I may restfully rely on.
But... the thing is there's this big elephant in the room — this API is non-customizable, inconvenient, and hard to use in terms of the app architecture. I can't write my own protocol wrapper around it to abstract my domain logic from implementation details or just simplify the usage at the call site. I can't configure my own format for log messages (this is debatable, since Console.app doesn't provide "naked strings" as Xcode 14 and earlier, but still). And what's most important — I can't conveniently retrieve the logs!
I can't implement the functionality where my user just taps the button, and the logs are sent on the background queue to my support email (eskimo's answer). They would have to go through this monstrous procedure of holding volume buttons on the iPhone, connecting their device to the Mac, gathering sysdiagnose, entering some weird Terminal commands (jeez, these nerdy developers...), etc. If it ever succeeds, of course, and something doesn't go wrong, leaving my user angry and dissatisfied with my app.
Regarding the protocol wrapper, I can't do something like this:
protocol Logging {
var logger: Logger { get }
func info(_ message: OSLogMessage)
}
extension Logging {
var logger: Logger {
return Logger(
subsystem: "com.my.bundle.id",
category: String(describing: Self.self)
)
}
func info(_ message: OSLogMessage) {
logger.info(message)
}
}
class MyClass: Logging {
func someImportantMethod() {
// ...
self.info("Some useful debug info: \(someVar, privacy: .public)")
}
}
I've been investigating this topic for 2 days, and it's the farthest I want to go in beating my head over how to do two simple things:
How to isolate logging framework implementation decision from my main code and write convenience wrappers?
How to easily transfer the log files from the user to the developer?
And I'm not the only one struggling. Here's just one example among hundreds of other questions that are being asked on dev forums: https://www.hackingwithswift.com/forums/ios/unified-logging-system-retrieve-logs-on-device/838. I've read almost all Apple docs which describe the modern Unified Logging System, I've read through eskimo's thread on Apple Developer Forum about the API, but I still haven't found the answer.
Maybe, I've misperceived this framework and it's not the tool I'm searching for? Maybe, it focuses on different aspects of logging, e.g. signposting, rather than logging the current state of the app? What am I missing?
Hello Everyone,
I'm trying to add badges to files in my File Provider Extension for macOS. I'm not trying to create my own Item decorations here, but use the default Icons provided by apple (such as com.apple.icon-decoration.badge.heart , com.apple.icon-decoration.badge.pinned). I've gone through the Sample code provided by Apple for Fruit Basket.
I've tried to replicate the same thing in my Extension as well but It seems I'm unable to display Icons. I'm not even getting any Error when the Icons are not being displayed, So I've been stuck for a month on this.
These are the Things that I've done below:
Folder Structure :
FileExplorer
|- FileProviderApp
| |- UI.swift
| |- ContentView.swift
|- Extension
|- extension.swift
|- item.swift
|- enumerator.swift
|- info.plist
According to the instructions given in the Documentation for Decorations here : https://developer.apple.com/documentation/fileprovider/nsfileprovideritemdecorating.
The implementation was done as follows:
content inside info.plist of the File provider Extension
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>NSExtension</key>
<dict>
<key>NSExtensionFileProviderSupportsEnumeration</key>
<true/>
<key>NSExtensionPointIdentifier</key>
<string>com.apple.fileprovider-nonui</string>
<key>NSExtensionPrincipalClass</key>
<string>$(PRODUCT_MODULE_NAME).FileProviderExtension</string>
<key>NSFileProviderDecorations</key>
<array>
<dict>
<key>BadgeImageType</key>
<string>com.apple.icon-decoration.badge.heart</string>
<key>Category</key>
<string>Badge</string>
<key>Identifier</key>
<string>$(PRODUCT_BUNDLE_IDENTIFIER).heart</string>
<key>Label</key>
<string>Heart Item</string>
</dict>
</array>
</dict>
</dict>
</plist>
In my extension's NSFileProviderItem I've also Implemented the protocol NSFileProviderItemDecorating. and the decoration's method as
static let decorationPrefix = Bundle.main.bundleIdentifier!
static let heartDecoration = NSFileProviderItemDecorationIdentifier(rawValue: "\(decorationPrefix).heart")
var decorations: [NSFileProviderItemDecorationIdentifier]?
{
var decos = [NSFileProviderItemDecorationIdentifier]()
decos.append(Item.heartDecoration)
return decos
}
I was expecting to see badges on the File items in Finder, but i got nothing. When I modified the FruitBasket Project to do the same i was able to see badges, but not when I try to implement it in my Extension.
Was I missing a step or is the issue something else ?
I am developing a FileProvider extension which will be launched for one or more domains. In the case where I have two domains, say with displayNames "Foo" and "Bar", the finder will then show "MyExtension - Foo" and "MyExtension - Bar" respectively after registering them with addDomain.
However, if I only have a single domain, let's say "Foo" – then I just see "MyExtension" rather than "MyExtension - Foo". Now ideally I'd like to be able to control the entire name, but barring that at least be able to show the displayName even with a single domain. How can I achieve that?
I am facing an issue while codesigning the Content/MacOS executable. The executable name is exactly similar to the .app file, and the signing certificates have not expired yet.
Steps followed to generate signed files:
Executed codesign on files within the .app folder.
Then executed codesign on the .app folder.
Tried to notarize with the new notarization tool.
Do we have to sign each individual file and folder?
Observations:
.DS_Store files were removed from the .app before signing.
Another app with the same certificate is able to sign correctly.
Content/MacOS contains multiple files, including the app executable. These files are signed except the main executable.
same installed_app after copying at another location showing signed.
Getting:
App Sandbox-Not enabled
Hardening-Enabled - Version 10.9.0
Notarization-Granted
Gatekeeper-Can't evaluate
Signed By- Can't verify signature
I am trying to populate the Finder comment field from extendedAttributes with the code bellow but it doesn't work.
Any idea why ?
var extendedAttributes: [String : Data] {
var attrs = [String: Data]()
let comment = self.caption
do {
let xmlPlistData = try PropertyListSerialization.data(fromPropertyList: comment as Any, format: .xml, options: 0)
attrs["com.apple.metadata:kMDItemFinderComment"] = xmlPlistData
} catch {
NSLog("Error during plist conversion: \(error)")
}
return attrs
}
My watch APP needs to keep Bluetooth connected with peripherals whether it is in the foreground or background, but the results of my test show that the connection in the background is very unstable, sometimes you can keep the Bluetooth on for a day, but sometimes it will be disconnected 50 times a day, and every time it is disconnected, I will immediately initiate a reconnection, it is certain that there is no problem with the peripheral Bluetooth, because I have another iOS device that has been stably connected to the peripheral, I want to know what causes this instability, and if there is any solution, if someone can provide relevant advice, I will be very grateful
Hello everyone,
I'm currently in the process of implementing platform SSO (Single Sign-On) in macOS and could use some guidance. I find myself a bit confused during the device registration phase, particularly because my Identity Provider (IdP) needs to support it. I'm wondering if Platform SSO will handle this automatically or if there are specific steps I need to take.
Additionally, I'm unsure whether I need to share the device signing and encryption key in my identity. Could someone please clarify this for me?
Finally, I would greatly appreciate it if someone could provide me with some sample code or starting pointers to help me get started on the right track. More into apart from OpenID, SAML protocol what else the Idp needs to change to support Platform SSO.
Thank you in advance for your assistance!
I want to traverse my local Google Drive folder to calculate the size of all the files on my drive.
I'm not interested in files or directories that are not present locally.
I use getattrlistbulk for traversing and it takes way too much time. I think it is because FileProvider tries to download metadata for the directories that are not yet materialised.
Is there a way to skip non-materialised directories?
I'm creating an App that can accepted PDFs from a shared context.
I am using iOS, Swift, and UIKit with IOS 17.1+
The logic is:
get the context
see who is sending in (this is always unknown)
see if I can open in place (in case I want to save later)
send the URL off to open the (PDF) document and
load it into PDFKit's pdfView.document
I have no trouble loading PDF docs with the file picker.
And everything works as expected for shares from apps like Messages, email, etc... (in which case URLContexts.first.options.openInPlace == False)
The problem is with opening (sharing) a PDF that is sent from the Files App. (openInPlace == True)
If the PDF is in the App's Document Folder, I need the Security scoped resource, to access the URL from the File's App so that I can copy the PDF's data to the PDFViewer.document. I get Security scoped resource access granted each time I get the File App's context URL.
But, when I call fileCoordinator.coordinate and try to access a file outside of the App's document folder using the newUrl, I get an error.
FYI - The newUrl (byAccessor) and context url (readingItemAt) paths are always same for the Files App URL share context.
I can, however, copy the file to a new location in my apps directory and then open it from there and load in the data. But I really do not want to do that.
. . . . .
Questions:
Am I missing something in my pList or are there other parameters specific to sharing a file from the Files App?
I'd appreciate if someone shed some light on this?
. . . . .
Here are the parts of my code related to this with some print statements...
. . . . .
SceneDelegate
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
// nothing to see here, move along
guard let urlContext = URLContexts.first else {
print("No URLContext found")
return
}
// let's get the URL (it will be a PDF)
let url = urlContext.url
let openInPlace = urlContext.options.openInPlace
let bundleID = urlContext.options.sourceApplication
print("Triggered with URL: \(url)")
print("Can Open In Place?: \(openInPlace)")
print("For Bundle ID: \(bundleID ?? "None")")
// get my Root ViewController from window
if let rootViewController = self.window?.rootViewController {
// currently using just the view
if let targetViewController = rootViewController as? ViewController {

else if let navigationController = rootViewController as? UINavigationController,
let targetViewController = navigationController.viewControllers.first as? ViewController {
targetViewController.prepareToLoadSharedPDFDocument(at: url)
}
}

I broke out the if statement for accessingScope just to make it easier for me the debug and play around with the code in accessingScope == True
func loadPDF(fromUrl url: URL) {
// If using the File Picker / don't use this
// If going through a Share.... we pass the URL and have three outcomes (1, 2a, 2b)
// 1. Security scoped resource access NOT needed if from a Share Like Messages or EMail
// 2. Security scoped resource access granted/needed from 'Files' App
// a. success if in the App's doc directory
// b. fail if NOT in the App's doc directory
// Set the securty scope variable
var accessingScope = false
// Log the URLs for debugging
print("URL String: \(url.absoluteString)")
print("URL Path: \(url.path())")
// Check if the URL requires security scoped resource access
if url.startAccessingSecurityScopedResource() {
accessingScope = true
print("Security scoped resource access granted.")
} else {
print("Security scoped resource access denied or not needed.")
}
// Stop accessing the scope once everything is compeleted
defer {
if accessingScope {
url.stopAccessingSecurityScopedResource()
print("Security scoped resource access stopped.")
}
}
// Make sure the file is still there (it should be in this case)
guard FileManager.default.fileExists(atPath: url.path) else {
print("File does not exist at URL: \(url)")
return
}
// Let's see if we can open it in place
if accessingScope {
let fileCoordinator = NSFileCoordinator()
var error: NSError?
fileCoordinator.coordinate(readingItemAt: url, options: [], error: &error) { (newUrl) in
DispatchQueue.main.async {
print(url.path())
print(newUrl.path())
if let document = PDFDocument(url: newUrl) {
self.pdfView.document = document
self.documentFileName = newUrl.deletingPathExtension().lastPathComponent
self.fileLoadLocation = newUrl.path()
self.updateGUI(pdfLoaded: true)
self.setPDFScale(to: self.VM.pdfPageScale, asNewPDF: true)
} else {
print("Could not load PDF directly from url: \(newUrl)")
}
}
}
if let error = error {
PRINT("File coordination error: \(error)")
}
} else {
DispatchQueue.main.async {
if let document = PDFDocument(url: url) {
self.pdfView.document = document
self.documentFileName = url.deletingPathExtension().lastPathComponent
self.fileLoadLocation = url.path()
self.updateGUI(pdfLoaded: true)
self.setPDFScale(to: self.VM.pdfPageScale, asNewPDF: true)
} else {
PRINT("Could not load PDF from url: \(url)")
}
}
}
}
. . . .
Other relevant pList settings I've added are:
Supports opening documents in place - YES
Document types - PDFs (com.adobe.pdf)
UIDocumentBrowserRecentDocumentContentTypes - com.adobe.pdf
Application supports iTunes file sharing - YES
And iCloud is one for Entitlements with
iCloud Container Identifiers
Ubiquity Container Identifiers
. . . .
Thank you in advance!.

Looking for any more documentation on FSKit - https://developer.apple.com/documentation/fskit?language=objc
I don't see any examples or sessions on it, but it looks fascinating. Attempted to try to put something together and immediately ran into failed at lookup with error 159 - Sandbox restriction
I am working on an app for a home automation device.
If I were using HomeKit exclusively I could add custom services or custom characteristics on standard services and these things would all be reported to my app via HomeKit. There is sample code from Apple that demonstrates how to do this.
When a Matter device is commissioned using HomeKit you might expect custom clusters and/or custom attributes in a standard cluster would be translated to appropriate HomeKit services and characteristics, but this doesn't appear to be the case.
Is there a way to have HomeKit do this?
If not it seems I would need to use Matter directly rather than via HomeKit to access custom features. But if I commission the device using Matter in my app then I understand a new fabric is created and the device would not show in the Home app. Maybe the user needs to commission the device twice, once with my custom app and once with the Home app? That seems like a poor user experience to me. Perhaps that is the price paid for using a cross-platform standard?
Is there a better way to get the same level of customization using Matter that I am able to get using HomeKit?
Prior to Sequoia, Mac Catalyst Apps worked fine when using group folders that started with group. They now get an alert that the Mac Catalyst app is trying to access data from other applications. This may also impact some SwiftUI developers.
According to this the documentation for the App Group Entitlements entitlement, on macOS we should begin use the Team Identifier instead of group.
Should Mac Catalyst follow the macOS or iOS rules for com.apple.security.application-groups? If they should need to follow the macOS rules now, that creates several issues for developers. We would now need separate build targets to pick up the different Entitlements files. More distressing is that we would need to do some kind of migration process to get our files to the new location. There wouldn't be a transparent way to do so where the user wasn't warned about the application accessing files that don't belong to it.
Any clarification on what Mac Catalyst developers should be doing to prepare for Sequoia would be greatly appreciated.
A little bit of background: If you make an app with no compiled Arm64 binaries in the Content/MacOS folder, MacOS erroneously identifies it as an Intel based app. After launching the app, MacOS will prompt the user to install rosetta, despite the app running fine natively. I found a simple solution to this issue, either include a do-nothing compiled binary to Contents/MacOS, or add
<key>LSArchitecturePriority</key>
<array>
<string>arm64</string>
</array>
to the plist.
The problem is this change only fixes the issue if you also change the BundleID. If you run the app even once with the bad configuration, MacOS seems to cache the intel flag somewhere based on the BundleID. It does not seem to be cached in the usual places.
How to reproduce: (On apple silicon)
You probably already have rosetta, and it is a pain to remove, so a VM is likely needed.
Make an empty app with Script Editor, export with file format: Application.
Replace Example.app/Content/MacOS/applet with a script of the same name. Make sure the old applet is gone, don't rename it and leave it in the directory. I used:
#!/usr/bin/osascript
display dialog "Hello, world"
Make it executable sudo chmod +x ./Example.app/Content/MacOS/applet
Run the app and observe that it asks you to install rosetta
Add the previously mentioned fix to you plist, including the BundleID change
Run it again and observe that it now works
Change your BundleID back. Running this now raises the rosetta prompt despite the fact that it runs fine on a clean install of MacOS.
Things I have tried:
Rebooting, no effect
Reforming the app, no effect
Reboot in recovery mode, no effect
lsregister -delete, no effect
~/Library/Preferences, ~/Library/Caches, /Library/Preferences, and /Library/Caches, none contain an entry for the BundleId
