Is CallKit still not available in certain countries? like China? If it is, is there a way to get a list of countries?

Hi everyone,
We’re integrating Apple Calendar (iCalendar) into our Codapet app but haven’t found any official Apple APIs for event management and synchronisation.
Currently, we use CalDAV with Apple ID authentication and an app-specific password (ASP), storing the ASP encrypted in our database and decrypting it for each API call. We’re looking for a more secure and recommended approach to this integration.
Does Apple provide dedicated APIs for calendar sync, or is there a better alternative to avoid sending the ASP with every request? Any guidance or best practices would be greatly appreciated!
Thanks!
Hi all,
I'm trying to set up universal links for my app but it's not working.
What I want:
cogover.com → Safari (website) - NOT my app
*.cogover.com (any subdomain like abc.cogover.com) → My app
What I did:
Added applinks:*.cogover.com in Xcode
Put AASA files on all subdomains
They work fine (checked with curl)
Problem:
All links still open in Safari, not my app.
I do not put AASA on my root domain cogover.com because I don't want open my app with root domain.
I have checked TN3155: Debugging universal links | Apple Developer Documentation but it only say about universal link works with both root domain and subdomains.
Weird thing I found:
I checked how Salesforce does it - their *.force.com subdomains work perfectly. But when I tried to check their setup, (https://force.com/.well-known/apple-app-site-association) doesn't seem to exist either! So how does theirs work?
Even stranger - Apple's CDN has their file cached at (https://app-site-association.cdn-apple.com/a/v1/force.com) but the actual domain doesn't serve it. Can Apple's CDN have a file cached even if it's not on the website anymore?
Thanks for any help!
I've successfully started the Live Caller ID Lookup example and initialized the PIRService.
I added several identities to the input.txtpb file, some with block: true and others with block: false.
Here is the file but modified phone digits:
identities {
key: "+40790123123"
value {
name: "Blocking 1"
cache_expiry_minutes: 7
block: true
}
}
identities {
key: "+972526111111"
value {
name: "Blocking 2"
cache_expiry_minutes: 7
block: true
}
}
identities {
key: "+123"
value {
name: "Adam"
cache_expiry_minutes: 8
block: false
category: IDENTITY_CATEGORY_PERSON
}
}
identities {
key: "+972526111112"
value {
name: "Identified Business Name 1"
cache_expiry_minutes: 1
block: false
category: IDENTITY_CATEGORY_BUSINESS
}
}
identities {
key: "+972526111113"
value {
name: "Identified Business Name 2"
cache_expiry_minutes: 1
block: false
category: IDENTITY_CATEGORY_BUSINESS
}
}
The main issue is that only the number marked as +40790123123 was actually blocked, while "Blocking 2" appeared as identified contacts with their assigned name displayed.
Notably, the only blocked number was a foreign number with a different country code than the number being called. The other numbers belonged to the same country.
Can someone clarify whether this is a bug in the example project or an issue with the data file?
Widgets on the widget is not responding to the touch properly. This issue is also affecting within the home screen widget in a way that the widget switches to light mode by itself even though I am in dark mode. Additionally, lock screen does not to respond once the lock screen widget has been edited. Is anyone else having this issue?
Hello,
I’m developing an app to detect movement past a strong magnet, targeting both Android and iOS. On Android, I’m using the Sensor API, which provides calibrated readings with temperature compensation, factory (or online) soft-iron calibration, and online hard-iron calibration. The equivalent on iOS appears to be the CMCalibratedMagneticField data from the CoreMotion framework.
However, I’m encountering an issue with the iOS implementation. The magnetometer data on iOS behaves erratically compared to Android. While Android produces perfectly symmetric peaks, iOS shows visual peaks that report double the magnetic field strength. Additionally, there’s a "pendulum" effect: the field strength rises, drops rapidly, rises again to form a "double peak" structure, and takes a while to return to the local Earth magnetic field average. The peaks on iOS are also asymmetric.
I’m wondering if this could be due to sensor fusion algorithms applied by iOS, which might affect the CMCalibratedMagneticField data. Are there other potential reasons for this behavior? Any insights or suggestions would be greatly appreciated.
Thank you!
At present, all my apps cannot display normally

Hello,
I noticed the new entitlement in iOS 26 under LiveCommunicationKit: Preparing your app to be the default dialer app.
My question is about eligibility:
If a developer account is registered in the EU, can any app add the Default Dialer capability, or is it restricted only to apps that provide real calling/communication functionality (e.g., WhatsApp, Telegram, Skype)?
If granted, does this capability allow the app to make/receive cellular calls and access call history, or is it limited only to VoIP-style scenarios through CallKit integration?
What are the minimum functionalities required to support this feature (e.g., having a dial pad, call history screen, etc.)?
Why must the developer account be registered in the EU to use this entitlement?
Thanks in advance for the clarification!
Hello there!
So Im trying to upload an app to the App Store for iphone and Ipad, but from the revision team the same message always appears, the app crash.
So I know the "it works on my computer" sounds bad but....works on my computer and my test system.
Dont know what to do since I dont know how to replicate the error.
This is the rely they sent me:
Issue Description
The app exhibited one or more bugs that would negatively impact users.
Bug description: at time of review the app’s interface went blank at launch.
Review device details:
Device type: iPad Air (5th generation)
OS version: iPadOS 18.4.1
Anyone has any idea on how can I replicate the error and maybe check the logs? Im completely blind on this one.
Hey there,
I have an app where I create custom Advanced App Clip Experiences for other businesses which seems to be a valid thing.
I do create them via API. Upon creation everything looks fine: when I go to App Store Connect -> App -> Advanced App Clip Experiences, I do see the new App Clip Experience I've just created. Their status is Received (as any other active experiences) and have a custom URL.
The issue is weird timing when the Advanced App Clip Experience actually becomes available on the iPhone (can be triggered via App Clip Code, etc). Some experiences become available literally immediately but others take days (some take 1-2 days, some take ~5 days).
I'm not sure why there's a bid difference for an Advanced App Clip to be actually active. Does anyone have any kind of experience with that? I don't change domain settings, app's settings, etc. I'm just creating a new experience (both via API or manually at App Store Connect) and I do have different "activation" times for different App Clips.
Same when I delete an Advanced App Clip Experience, it will still be available for next couple days.
I get there might be caching stuff, etc. But the difference is quite huge and makes no sense since as I've mentioned some clips become available immediately but some takes days to be available.
Thank you!
Hi, I work at OneSignal, a third-party SDK, and have the following two crash reports submitted by a client for the same issue. Because the crash originates from our SDK, even if the root cause may be elsewhere, the onus is on our team to try to resolve this crash. Additionally, my information is limited as this is not our own crash report.
I'm trying to figure out why this crash happens and how we can address it within our SDK.
Crash Reported:
Fatal Exception: NSInvalidArgumentException
[NSMutableDictionary __addObject:forKey:]: object cannot be nil
Context:
Our SDK makes a call to [NSUserDefaults(NSUserDefaults) objectForKey:] on the standardUserDefaults and passes in a non-null key. It appears further up the call stack, a null value is being added to a dictionary. I assume this is the innards of how the search list is generated.
Additional Information:
The client states that it seems to happen only once per user and the scale is not extremely high but it is increasing. They are unsure what happened and when. They don't have much information about the devices except it has happened on iOS 18.

Hi everyone,
We're using the react-native-device-activity package to implement app blocking via Apple's Screen Time API. The blocking functionality works well: when the user selects apps and taps "Done," those apps get blocked as expected.
However, we're facing an issue with unblocking apps that the user later unselects. Even after the user unchecks some apps and taps "Done" again, those previously selected (now unselected) apps remain blocked and still show the shield.

Hi Apple engineering team,
I’m trying to integrate the new Live Caller ID Lookup (PIR) on iOS using your pir-service-example code as well as a custom mock server in Vapor, but the extension never advances past the /issue/token-key-for-user-token step. I’ve tried both:
1. Official Example
Cloned https://github.com/apple/pir-service-example
Ran PIRService locally
Confirmed that
GET /.well-known/private-token-issuer-directory → 200
GET /issue/token-key-for-user-token → 200 (DER bytes, correct SPKI)
No POST /issue ever fires
2. Mock Server (Vapor)
Implemented all five endpoints (/config, /.well-known/private-token-issuer-directory, /issue/token-key-for-user-token, /issue, /queries)
Verified with curl and openssl asn1parse that:
GET /.well-known/private-token-issuer-directory
Content-Type: application/private-token-issuer-directory
{ "issuer-request-uri":"https://…/issue", "token-keys":[…] }
GET /issue/token-key-for-user-token
Content-Type: application/octet-stream
<DER bytes>
Added Cache-Control: public, max-age=3600 on directory and SPKI
Stubbed POST /issue to always return { "token": "" }
Still no POST /issue request from the extension
Reproduction Steps
Install and enable a Live Lookup extension pointing to my server.
Trigger an incoming call on device.
Watch server logs—only see the two GETs, never /issue or /queries.
Expected Behavior
After fetching the SPKI DER, the framework should issue a POST /issue call (Privacy Pass flow) and then POST /queries.
Observed Behavior
Stuck in an infinite loop of:
GET /.well-known/private-token-issuer-directory
GET /issue/token-key-for-user-token
(repeat…)
No progression to the /issue or /queries endpoints.
What I’ve Tried
Verified JSON kebab-case and headers exactly match examples
Confirmed SPKI DER is valid via openssl asn1parse
Added Cache-Control headers
Tested on real device, localhost url, and ngrok public URL
Mocked a valid-looking token response
Could you advise what additional requirement or format detail I’m missing that prevents from advancing past /issue/token-key-for-user-token?
These are the main files:
LiveLookupExtension.swift
routes.swift
service-config.json
Thanks in advance!
When the iPhone is set to 12-hour time format, obtaining a timestamp similar to "2025-07-18 16:29:00" fails
We developed a "Default Translation App" following the guide: https://developer.apple.com/documentation/translationuiprovider/preparing-your-app-to-be-the-default-translation-app.
I have already configured everything that needs to be configured according to the document, but there is still this problem

Hello! I am a relatively new Apple developer and am almost done with my first app. I am implementing the Screen Time API to my app because the app is designed to help the user digitally detox and I am trying to make it so the user can select which apps they would like to monitor from a list of their apps on their phone so I am using the family activity picker but I just can't extract the data needed to track the apps. I am wondering how to do this. Thank you!

I'm sitting at my house and trying to sign my test device out of my apple ID so I can sign into a Sandbox user, but now I have an hour to kill because of this terribly broken "security" feature that thinks it's in an unfamiliar location, despite being at the only location it's ever known. Looks like I'll just be disabling this feature all together.
Especially as a device with Developer Mode enabled, which gets reset regularly, there should be additional options here. Come on!
Weatherkit stopped again providing next hour rain data for United kingdom and ireland
I've been working a lot with the FamilyControls API and App Shield recently but have encountered a problem with no documentation. I used the FamilyActivitySelection to select the app store to shield(This is just for testing), and then printed out the application token:
1wfY¸êB ò S« öi #×(É?âðw ù/jQ ¿ J ïE¢? ·¿ º<Òd?ý r7¥Ãn N átJ¹ÿ85B_{VAF fC8. ,,¸¯3 T7F ±õü; ¹?v@¯ô Ä \-õ# Ò
I know the application token is a Codable object so I was wondering,
How do I create an application token using the Token<Application> initializer
init(from: any Decoder) throws
Creates a new instance by decoding from the given decoder.
Using the above data? Do I have to encode first in order to decode it?
For reference, the code I tried to use is:
newValue.applicationTokens.encode(to: JSONEncoder)
if let encoded = try? JSONEncoder().encode(newValue.applicationTokens) {
data = encoded
print(String(data: data, encoding: .utf8)!)
}
if let app = try? JSONDecoder().decode(Token<Application>.self, from: data) {
let token = Application(token: app)
print(token)
} else {
print("didn't work")
}
But it prints didn't work every time.
What should I do differently?
