After updating to watchOS 11.1, updates using WidgetCenter.shared.reloadAllTimelines() in WKRefreshBackgroundTask stopped working. When the background task is triggered, it gets data from the phone and updates the WidgetKit complications. But now the refresh call WidgetCenter.shared.reloadAllTimelines() does not update the complications.

I've developed a new Quicklook data-based preview extension for a custom file type that generates an image preview of the file. I previously used a Quick Look generator plug-in but support for it was deprecated and now removed in macOS Sequoia.
My app opens files using a
open(url.path, O_RDWR | O_NONBLOCK | O_EXLOCK)
call. The locking flags are used to prevent other clients from writing the file if it's already open.
I discovered that when Finder is showing the “large” file previews (such as when in column or gallery modes) from a SMB share, the open call fails with EWOULDBLOCK as if the file is locked.
It does work just fine on local files. Opening with O_SHLOCK also has the issue. Surprisingly it does work just fine for previews that return Plain Text data instead of Image data.
Using the lsof command, it seems like the Quicklook process has some kind of lock on the file.
This is the output of the lsof command:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE
QuickLook 48487 XXXX txt REG 1,15 125000611 3161369
Attached is a test project that tries a few different opening and locking functions. It also includes a test file and a sample image preview extension that displays a red square.
When everything is working, regular console messages show the progress of the tests. When the file is on a SMB share and selected in Finder Gallery mode, the open test will fail with a fault message in the console.
Notably, locking with flock works, which is weird because it should have similar semantics according to the man page for open(2).

After building my app with Xcode 16 beta 6 I'm getting this warning in my AppIntents.
Encountered a non-optional type for parameter: computer. Conformance to the following AppIntent protocols requires all parameter types to be optional: AppIntents.WidgetConfigurationIntent, AppIntents.ControlConfigurationIntent
The intent looks something like this
struct WakeUp: AppIntent, WidgetConfigurationIntent, PredictableIntent {
@Parameter(title: "intent.param.computer", requestValueDialog:"intent.param.request_dialog.computer")
var computer: ComputerEntity
init(computer: ComputerEntity) {
self.computer = computer
}
init() {
}
public static var parameterSummary: some ParameterSummary {
Summary("Wake Up \(\.$computer)")
}
static var predictionConfiguration: some IntentPredictionConfiguration {
IntentPrediction(parameters: (\.$computer)) { computer in
DisplayRepresentation(
title: "Wake Up \(computer)"
)
}
}
@MainActor
func perform() async throws -> some IntentResult & ProvidesDialog {
}
}
According to the docs though specifying optional is how we say if the value is required or not. https://developer.apple.com/documentation/appintents/adding-parameters-to-an-app-intent#Make-a-parameter-optional-or-required
So is this warning accurate? If so, how do I specify that a parameter is required by the intent now?
Not sure if my question is weird or not, but I didnt find any documentation about an sdks access to an apps documents directory.
Im assuming that because sdk is part of the sandbox that it can access and read from the documents directory? i.e. if i used
NSFileManager.defaultManager.URLForDirectory(
directory = NSCachesDirectory,
inDomain = NSUserDomainMask,
appropriateForURL = null,
create = false,
error = null,
)
to write a file called "file.txt", then any sdk my app used has the ability to access the contents of said directory?
If yes, why isnt this considered something more worth mentioning? usually in filemanager tutorials they never warn about this.
FYI: Im asking more for iOS and iPadOs then MacOs.
There's a 128mb limit for donating items to core spotlight. As far as I understand, there's a warning that shows in the Xcode console when either approaching or hitting that limit. It would be great if there was an API to check the current status of available storage for QA purposes to see if we're either donating too much or can donate more. Thanks!
I’ve implemented an Intent Extension and added support for handling the INSendMessageIntent in the intent handler class.
Currently, this intent is automatically visible in the Shortcuts app by default. However, for security reasons (as it involves handling phone numbers), I want to restrict the use of this intent to Siri only and ensure it does not appear in the Shortcuts app.
Has anyone encountered this requirement before or knows a way to prevent the intent from appearing in the Shortcuts app, while still keeping it functional via Siri?
Looking forward to your suggestions!
Hi!
I am moving a contact management app (Contact Clearout) to CNContactStore.
For users to have full info when choosing between duplicates they need the creation and modification dates.
I don't want to have to use an extra access to ABAddressBook just to get these and I can see they are on the CNContact objects.
How to do I get these values?
Thanks
I'm working on adding CFBundleDocumentTypes to my Info.plist so that a user can share an image from other apps on their device and have it open inside my iPhone app.
I seem to be able to get this to work for sharing a single photo from the Photos app, but not for (1) multiple photos from the Photos app or (2) images from Safari.
One thing that makes this difficult is that my changes to Info.plist sometimes have no effect. I can remove CFBundleDocumentTypes and still see the icon, for example. Or I can add a new accepted UTI, but it has no effect. I've tried cleaning and rebuilding, deleting and reinstalling the app...no success. I tried in the simulator, too, and even Erase Content and Settings didn't force changes to be applied. I'm not sure what else to try here.
Anyway, I'd like my app to appear in the Share sheet for photo(s) from the Photos app, Mail and Safari, in particular, but really from any app that supports sharing photos.
I can share the config that seemed to work, but since changing it doesn't always have an effect, I can't guarantee that this was the one that worked. At the moment, it doesn't work, but I'm not sure why. Here it is:
<key>CFBundleDocumentTypes</key>
<array>
<dict>
<key>CFBundleTypeIconFiles</key>
<array/>
<key>CFBundleTypeName</key>
<string>Image</string>
<key>CFBundleTypeRole</key>
<string>Viewer</string>
<key>LSHandlerRank</key>
<string>Alternate</string>
<key>LSItemContentTypes</key>
<array>
<string>public.data</string>
<string>public.jpeg</string>
<string>public.png</string>
<string>public.image</string>
<string>public.gif</string>
<string>public.url</string>
<string>public.content</string>
</array>
</dict>
</array>
<key>LSSupportsOpeningDocumentsInPlace</key>
<true/>
In my code, I also defined the following method in my SceneDelegate (though I think the problem is just with Info.plist):
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
Here are my questions:
How do I make sure that my changes to Info.plist apply? Is there a cache somewhere that I have to force to clear? This is the trickiest part of this, because I can't reliably try an experiment and see if it worked.
Adding the specific image UTI’s (public.jpeg, public.png) seemed to help, even though those types should conform to public.image, which conforms to public.data and public.content. Is it actually necessary to specify those?
If the user selects multiple photos in the Photos app, my app doesn’t appear, but other third-party apps on my phone do. How can I support multiple photos?
This configuration doesn't reliably show my app for Safari images - what do I need to do to make that happen?
I had to use “public.data” when I briefly had Safari sharing working, but there doesn't seem to be a way to get a UTI from UIOpenURLContext. Right now, my code just tries to load the data as an image and aborts if UIImage(data:) returns nil. Is this a safe way of doing this? Is there a way to get the UTI for the data?

Hello.
Our app uses PTT framework and "Always" location tracking at the same time. By some reason, after backgrounding app, Dynamic Island shows only location tracking icon instead if PTT icon. And when user taps on it - application foregrounding instead of system PTT UI show. Only after first incoming PTT user can access system PTT UI.
Is it a bug or intended behaviour?
Prior to iOS18, the incoming/outgoing call history display in the Phone app matched the CallDirectory content, but starting with iOS18, changing the information tied to the same number results in the incoming/outgoing call history not matching the CallDirectory content, as it remains unchanged before the change. Is this a strongly intended change? If not, we would like to have it reverted back to the way it worked before iOS18.
Befor iOS18
Register the target phone number and name1 to CallRirectory
Incoming call using the target phone number
The target phone number and name1 is recorded as an incoming call history
Register the target phone number and name2 to CallRirectory
Incoming call using the target phone number again
The target phone number and name2 is recorded as an incoming call history
Also 1st incoming call history’s name is changed to name2
After iOS18
Register the target phone number and name1 to CallRirectory
Incoming call using the target phone number
The target phone number and name1 is recorded as an incoming call history
Register the target phone number and name2 to CallRirectory
Incoming call using the target phone number again
The target phone number and name2 is recorded as an incoming call history
But 1st incoming call history’s name is still name1
Why does this difference occur?
Is there any way to limit use of the iOS 18 Live Caller ID extension to subscribed users? My team has been trying to figure out a workable approach to only allow full call blocking / identification via this feature for users with an active subscription and so far we have not found a workable approach.
One solution we’ve looked into is invalidating access tokens on the backend and only calling refreshPIRParameters(forExtensionWithIdentifier:) for users with a current valid subscription but it seems that this won’t work since the device will attempt to refresh on its own eventually.
We’ve also looked into swapping out the userTierToken in the extension based on subscription status but this also does not seem to be possible.
Is limiting/modifying this feature's functionality based on subscription status just not possible, likely by design due to the privacy-focused nature of it, or is there some other approach we’re overlooking?
Hi,
My env. is ..
Xcode: Version 16.2 (16C5032a)
macOS Sequoia: Version 15.1
And I have 2 problems.
Please give me the advice..
Failed Message.
When I run the automatically generated app as it is, the following error(warning?) message appears in the terminal.
Can't find or decode reasons
Failed to get or decode unavailable reasons
NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed
Not on the simulator
And the result is not running in the simulator, but instead appears as a window. (The simulator works fine when launched separately, but the app from the current project doesn’t show up in it.)
Hey,
I'm trying to update my old app that used DarkSky to WeatherKit, and struggling. I always get:
ailed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)"
This is regardless if I do it on my iPad, or in the simulator. I have done the following:
Selected WeatherKit on the Capabilities and App Services tabs of the Identifier section on developer.
Put it under signing and capabilities in XCode
I've tried making a new provisioning profile, cleaning build folder, etc. Not sure what to do here. I suspect part of this problem is that I developed this app in 2018 and now I'm trying to update it.
I am able to run the app on TestFlight, but not as an internal tester. Apple won't let me, so I have to add myself as an external tester.
Thanks for any help you can provide!
I'm writing an app that uses text to speech. On the physical Iphone 12 it works but on the simulator I don't get any speech from my app.
I tried the following to enable.
Settings -> Accessebility -> "Spoken Content" -> "Speak Selecton" to ON (green)
in Voices I added the German Anna that I use on my Iphone with the downloaded enhancements.
The speech test works in this menu but not in my app. What am I missing ?
Cheers,
Gerhard
Hi everyone. Does anyone know if there a way to get a list of watch faces for a paired Apple Watch, or to set the current watch face? Or is this just not allowed?
Have looked through the WatchKit, WatchConnectivity, and WatchOS documentation and haven't found anything.
Hello,
Could you please help me with the below,
How to display a toast message to the user in CarPlay after a successful operation?
How to show a spinner or an activity indicator just before performing some operation?
I have referred to the CarPlay pdf design guidelines in which I couldn't find support for the above two. But I could see a loader within a button in one of the default apps in CarPlay simulator.
Kindly help me with these queries
In the past it was possible to use the Today Extensions to do some background processing without having the unlock the phone. This was extremely useful for application, but now with the current WidgetKit we face the problem of sometimes having to enter the lock screen code if face Id fails, or is not available.
With the Today Extension, we were able to initiate a location request and send an HTTP request. Is there any way to get a similar request chain across on the latest OS? Maybe there is something out of the box that we are not thinking of.
Our application is highly time sensitive and in the field the lock screen delay can be a big problem and put a users safety at risk, so this is why I ask.
I have been using the hourly weather forecast API, for some reason sometimes the API fails with 400 Bad Request, but on retrying just a minute later the call successfully returns data. The start and end time are 2 days apart so I don't think it's an issue with the time frame.
The failed calls also don't return any reason so not sure what is the exact failure.
Has anyone encountered this issue or knows why this might be happening??
Thanks!!
when we launch the application and change the language from german/french to english or any other language then in also it is changing app language, but bluetooth connection screen with pair or cancel alert is showing on previous selected language. Since that alert is system alert, is there any wayto debug/resolve that issue.
