Summary:
I'm developing an iOS audio app in Flutter that requires background audio playback for long-form content. Despite having a paid Apple Developer Program account, the "Background Modes" capability does not appear as an option when creating or editing App IDs in the Developer Portal, preventing me from enabling the required com.apple.developer.background-modes entitlement.
Technical Details:
In the app that I am developing, users expect uninterrupted playback when app is backgrounded or device is locked similar to Audible, Spotify, or other audio apps that continue playing in background
The Problem:
When building for device testing or App Store submission, Xcode shows:
Provisioning profile "iOS Team Provisioning Profile: com.xxxxx-vxxx"
doesn't include the com.apple.developer.background-modes entitlement.
However, the "Background Modes" capability is completely missing from the Developer Portal when creating or editing any App ID. I cannot enable it because the option simply doesn't exist in the capabilities list.
What I've Tried:
Multiple browsers/devices: Safari, Chrome, Firefox, incognito mode, different computers
Account verification: Confirmed paid Individual Developer Program membership is active
New App IDs: Created multiple new App IDs - capability never appears for any of them
Documentation review: Followed all Apple documentation for configuring background execution modes
Different regions: Tried changing portal language to English (US)
Cache clearing: Logged out, cleared cookies, tried different sessions
Apple Support Response:
Contacted Developer Support (Case #102633509713). Received generic documentation links and was directed to Developer Forums rather than technical escalation.
Has anyone else experienced the "Background Modes" capability missing from their Developer Portal?
Has anyone successfully used the App Store Connect API to add background-modes when the GUI doesn't show it?
What's the proper escalation path when Developer Support provides generic responses instead of technical assistance?
Things I have attempted to solve this:
audio_service package: Implemented as potential workaround, but still requires the system-level entitlement
Manual provisioning profiles: Cannot create profiles with required entitlement if capability isn't enabled on App ID
Other perhaps important facts about the environment where I am building the app:
macOS Sonoma
Xcode 15.x
Flutter 3.5.4+
Apple Developer Program (Individual, paid)

On a device with approx 800 contacts, the sheet presented when tapping ContactAccessButton with multiple matches briefly appears (.25 seconds) before disappearing, leaving the view below in a dimmed, slightly zoomed out, non-interactive state as if a sheet were being presented. Swiping down dismisses the invisible sheet returns the underlying view to a normal state.
Is there a way to avoid this? It appears possibly similar to https://developer.apple.com/forums/thread/762077

I'd like to allow users to select apps to shield from a DeviceActivityReport (similar to how Apple's Screen Time Settings activity report allows a user to "add limits" to a selected app in the report.
What I need to do is pass an appToken from the DeviceActivityReportExtension to my app.
I realize the extension is sandboxed and doesn't allow "private" data to be seen outside of the sandbox. The docs state:
To protect the user’s privacy, your extension runs in a sandbox. This sandbox prevents your extension from making network requests or moving sensitive content outside the extension’s address space.
However, tokens aren't "sensitive".
I want to pass a token set out of the sandboxed extension so users can select certain apps from the report that my app can use for setting limits, etc.
I thought using App Groups and saving data with UserDefaults with a suiteName for my app group would do it, but it doesn't appear to allow me to pass the token data.
Yes I'm using the same KEY for both as I set a config enum to ensure it's the same and I can pass tokens successfully between other extensions/apps in the app group, but not the report extension.
It seems the app and the extension have their own stores as the report extension can write to and read from a store but despite being the same suiteName, other apps in the app group don't get or send data to the Report Extension. I realize this is probably due to the design with the sandbox to protect user privacy, however it seems an exception should be made for passing tokens (or even better allow passing through another method like a callback, etc).
Is there ay way to accomplish passing a token from the sandboxed report extension to my app?

I've discovered a bug in the Phone app on iOS related to how long verdicts are displayed.
When a call is identified by a third-party Caller ID app, long verdicts display correctly during the call (they auto-scroll) and in the call log (with an ellipsis at the end). However, on the call details screen, the text is strangely truncated - showing only the beginning of the string and the last word.
For testing, I used this verdict: "Musclemen grow on trees. They can tense their muscles and look good in a mirror. So what? I'm interested in practical strength that's going to help me run, jump, twist, punch."
I'll attach a screenshots demonstrating the problem:
I'd like to set the recordingYear in my Spotlight File Importer extension but the property is missing from CSSearchableItemAttributeSet
e.g. in the resulting in mdls I'd like to see:
kMDItemRecordingYear = 2008;
This would allow me to search in Finder by the recording year criteria.
There is a recordingDate property and I tried setting it to Date that only has a year but it didn't work. It just resulted in this:
kMDItemRecordingDate = "2008-01-01 00:00:00 +0000";
Hi all,
From what I’ve seen on forums and other sources, it appears that nothing can be done to set the contact poster programmatically. Setting the imageData property affects only the thumbnail image. Does anyone know if this is explicitly documented somewhere? I need this information for a POC document. I watched the iOS 17 keynote (where it was introduced), the Platform State of Union, and other WWDC videos, but I couldn’t find any mention of it. The Contacts framework documentation only explains what can be retrieved from this property and doesn’t mention any way to set the contact poster.
If anyone has any information on this, please help!
Thanks in advance!
I'm unable to have stickers show in messages even with a new iOS app and a sticker pack extension target.

Hi Team,
We’re encountering a device-specific issue with our SMS Message Filter extension. The extension works as expected on an iPhone 11 running iOS 16.6, but it does not trigger on an iPhone 12 Pro running iOS 16.7.
Key Observations:
The extension is implemented using ILMessageFilterExtension and calls messageFilterOffline(appGroupIdentifier:for:) from our shared library.
The App Group is properly configured and accessible across the app and extension.
The extension is enabled under Settings > Messages > Unknown & Spam.
There are no crashes or error logs reported on the affected device.
The issue is consistently reproducible — it works on one device but not the other.
We’re wondering if this could be a regression or a device-specific behavior change introduced in iOS 16.7.
Has anyone encountered similar inconsistencies in Message Filter extensions across different iOS versions or device models?
Any guidance or suggestions would be greatly appreciated.
Thanks in advance!
I am building a screen time management app. It has the main app target, and then three extensions - those are the four targets in Xcode. The three extensions are:
Shield
Device Activity Monitor
Device Activity Report Extension
I requested "Family Controls (Distribution)" capability from Apple for the main app target / bundle ID, and it got approved.
Do I need it for the extensions too? Because previously I had "Family Controls (Development)" for the extensions...
Hey guys! I've recently noticed a number of PaaS'es and CPaaS'es offering bulk outgoing messaging using the iMessage the same way it's done with the SMS.
I always thought that iMessage sort of only allowed businesses to send outgoings subject to user contacting their account first (to avoid being spammed). But then there's those I mentioned above.
Have you faced anything like this? Did Apple make changes to the model so that businesses can now initiate conversations with users? If so, how does it work?
I'm trying to fade in the sound used in my alarm app but currently there's no way to achieve this since the alarm sound loops and if i add a fade-in at the beginning of my audio, every time the audio loops the fadein happens.

Hi,
I'm using ScreenCaptureKit on macOS 14+ to record a single window. I've noticed that the Presenter Overlay only appears when capturing the entire screen, but it does not appear when recording a specific window or a region.
Is there a way to enable the Presenter Overlay while recording a single window or a defined region, similar to how it works with full-screen capture?
Any guidance or clarification would be greatly appreciated.
Thanks in advance!
Hi everyone,
I’m currently developing a parental control app that uses the Screen Time API (FamilyControls, ManagedSettings, DeviceActivity). I have a question regarding the customization limits of the Shield UI in ManagedSettingsUI.
From the documentation, I understand that we can customize the ShieldConfiguration (background color, blur style, icon, title, subtitle, button labels, etc.). However, I’d like to clarify a few points before finalizing the design:
1. Is it allowed (or technically possible) to display custom media content, such as videos, animations, or interactive elements, inside a custom Shield?
2. Are there limitations on the text length for the title and subtitle fields (e.g. maximum number of characters, multiline support, truncation behavior)?
3. Can the Shield be personalized per user (for example, showing a different title or color scheme based on user preferences or device state)?
4. Are there App Store Review restrictions or UI guidelines that define what a Shield should or should not contain (for instance, whether the Shield can resemble a mini-app experience)?
I want to ensure that the implementation fully complies with Apple’s technical and design expectations before submission.
Thanks in advance for any official clarification or best practices on how far we can go with Shield customization!
Best regards,
Ferdinand
I am working on a Flutter application which is use solely to collect data from a bluetooth low energy (BLE) peripheral and then upload the data to our cloud.
The application runs in the background 99% of the time after the initial login and BLE pairing which is causing us some issues.
After the Application is backgrounded it would work for a day to 2 days and then stop working. (What I mean with working is to download data from the BLE peripheral and then upload the data to our cloud). Once the data syncing has stopped it would take up to 12 hours until data starts flowing again.
I have read in a couple of places that iOS implements some sort of "budget/heuristics" when the application is running in the background to keep track of the application and when this "budget" is used up iOS will stop servicing the application until iOS decides that the application can run in the background again.
My question, is it possible via a enablement or some other mechanism to prevent iOS from blocking our application from running in the background to enable 24/7 periodic data uploads every 30 minutes.
We have implemented the following so far;
The data sync process is triggered from the BLE peripheral using a notification. This notification is sent every 30 minutes.
Each sync duration is currently 24 seconds on average, we are working on reducing this to below 10 seconds.
We implemented State Restoration to assist iOS in starting the application more efficiently.
We are considering using Silent Push Notifications from the Cloud to wake up the application when data hasn't synced in 6 hours.
Any assistance would be high appreciated.
I found that in iOS 18.5, DeviceActivityCenter startMonitoring cannot start multiple monitors, even if their names and periods are different, and restarting the phone cannot solve it. My app uses DeviceActivityCenter, which makes the entire function unusable. (I have less than 20 monitors)

Hello
Having trouble getting associated domain to work in our project. It was working when we used Branch, but our company wants to host the domain ourselves.
This is a multi-scheme project, using .xcconfig files to define the correct entitlement per Build.
The relevant entitlement file has:
com.apple.developer.associated-domains
applinks:bm.ddcas.ai in the
....{other irrelevant test associated domains....}
The project Team and App ID are taken from the Identifiers screen where the Identifier capabilities has 'associated domains' ticked on. I've also checked elsewhere on AppleDeveloper/Connect to be sure.
When we used Branch with domain key app links: bmstores.app.link this worked fine.
With https://bm.ddcas.ai (our own host) which is publicly available and has an aasa file in both the main directory and /.well-known, typing this in safari or anything just doesn't attempt to link to the App.
The iPhone is in developer mode, and using the developer menu associated domains diagnostic tool, typing https://bm.ddcas.ai results in the diagnostic saying 'The url is a Universal Link for the app with identifier **********.***etc (the app is installed on real iPhone 12, iOS 18.6.2 and my Xcode is 16.4)
However, it just doesn't work if we type in https://bm.ddcas.ai and results in a Safari message of '400 not found' and the 'nginx' shows.
We have read innumerable Apple Dev posts and StackOverflow posts, as well as several step by step 'how to's' online but this just isn't working.
The aasa file is at https://bm.ddcas.ai/apple-app-site-association and is setup as follows:
{
"applinks": {
"apps": [],
"details": [
{
"appID": "{my Team ID}.{my App ID}",
"paths": [
"*"
],
"components": [
{
"/": "/verification",
"?": {
"verification_code": "[A-Za-z0-9]{6}"
},
"comment": "Matches verification code path"
}
]
}
]
}
}
Our Server guys say the website (bm.ddcas.ai) is public and hosted, it just doesn't have a /verification path as they say it should redirect before reaching that.
Also, our Android redirect works using this site, so this appears to be something specific Apple code is looking for.
What, please, are we likely to be missing as it does not seem obvious from the Apple documentation or any of the resources I have checked online. Normally we can figure anything out, but getting nowhere here so the help is appreciated.
Hello!
I've been trying to get assessment mode working on my application. So far so good, seems to work on almost all of the laptops, except one. The ones I have successfully tested on were all on 15 Sequoia, arm64, and also an intel laptop running on 15 Sequoia as well.
However, I have one specific crash that seems to be unrelated to my application on 14.5 Sonoma, 2019 intel. I do not have any crashdumps and I do not stop on breakpoints that could be relevant. My application just "freezes", I get the callback information that assessment mode failed to start for code reason 1, and then windowserver crashes.
I do not see any crashdumps related to my application.
Maybe some of you have a specific idea what am I doing wrong? It's a bit interesting that It only happens on this device.
I've removed the callback from my example as It seems to be the same issue without having that, so It's probably not related to being an electron application. Entitlements are properly set, provision profile properly used.

I am working on enabling app clip experience for one of our products, where App X would use default appclip url of App Y to launch an experiences using UIApplication.shared.open(defaultAppclipUrl).
Im successfully able to build and submit to appstore by testing via local expereince, but later noticed a strange behaviour in production without local expereince setup, where tapping a button in App X (with default appclip url) fails to launch the appclip for the first time but loads fine from the second try.
I learned that in background Apple would make a API call to fetch details about app clip availability in store and then proceed to launch app clip locally, hence the delay->timeout->failure for first tap.
Once the invocation starts working it would be consistent. After couple of minutes of break say 20m, it again fails for 1st time. I'm assuming that iOS is invalidating the cache on device regarding availability of appclip in store and hence the API call is made again and there is a delay and failure.
can you please help us with this issue.
