Hi everyone, I’m working as an IT engineer in the cruise industry and need to troubleshoot passenger complaints about Apple’s new RCS messaging feature (introduced with iOS 18). Could someone help confirm which domains and ports iPhones use when they send RCS messages? My firewall team wants specifics: domains (or subdomains) that need whitelisting and the ports involved. Any official or community-sourced info would be super helpful—thanks in advance!

Hi team, We need to identify the domains used by macOS Software Update so they can be bypassed by our NETransparentProxy. The Apple support article below lists Software Update and several other Apple service domains. At the moment we’re unsure whether we should only bypass the Software Update and Beta Software domains, or whether we also need to bypass domains used for certificate validation, device management (Apple Business Manager / Apple School Manager / Apple Business Essentials), network provider updates, Apple Diagnostics, etc. We also need the specific IP ranges used exclusively by Software Update. The document shows Apple’s entire IP range; for IPv4 you can allow outbound connections to 17.0.0.0/8. https://support.apple.com/en-in/101555

The question: Is there any chance that Apple will integrate Intune SDK into Apple apps such as Mail or Calendar, or create Siri-compatible Intune SDK-integrated versions of Mail and Calendar? The reason for the question: My team has been asked by VIPs in our company (e.g. execs and board members) if Siri can be used with Outlook, and the only way is through Shortcuts or by adding the Outlook account to Mail. Both of these options would violate our security policies for these reasons: Since our company policy and federal regulations don't permit us to allow access to company resources on non-MAM-protected apps, we can't allow our users to login to the Mail app and make full use of Siri, due to the lack of MAM controls for Mail and Calendar. We only allow users to transfer data between policy-managed apps which have integrated the Intune SDK allowing us to enforce DLP and other security measures. The only way to enable Shortcuts would be to disable these security measures.

Hey. If i have a new idea for apple how can i reach out for you?

Hi Team, Could you please share how to change/extend the expiry date of the existing iOS Distribution (In-House) certificate? Since the membership renewal date is in March 2026 and the iOS distribution(In-House) certificate expiry date is in Feb 2026. We use to distribute the mobile apps using the product intunes (Company portal) and via direct download link. Please suggest since this certificate is used by multiple mobile apps by the users which can affect lot of iPhone users? Thank you in advance Deepak

"If your app includes any links outside the app, or offers any in-app or other purchasing opportunities, make sure these are behind a parental gate" Super Awesome and Kidoz are proving with a parental gate on ad click and they also claim that all ads are manually approved (another criteria for ads in Kids apps). So these two are the only ad networks we can use moving forward. Or we can use ad networks like Admob as well? I dont intend not to be in Kids category - so leaving Kids category is not a choice.

Both falls in same family group Child is under 13 yrs old Screen Time enabled in both device and parent device can see child in Screen Time.

The MDM was installed correctly and other commands are working fine. I have tried to send the InstallProfile with custom configuration to the device, but it was displayed as not signed. How to sign the payload for InstallProfile command and where it should be included in the payload / command?

short version question: why some users after deleting and downloading back my in-house app, cannot start the new process for approving developer, but instead it tries to start and then crashes immediately? long question version I am maintaining an in-house distributed enterprise app. due to update in iOS 18 update here users need to trust the developer via a new procedure that involves restarting device and inserting the phone code. after thousands (more or less 30.000) of users with no issue at all, some of them has this problem, the old (expired)trust seems to be persistent and never updated. Standard events a user deletes the app via settings > general > VPN & device management or via classic persistent touch procedure checks no other presence of the app is on the device via spotlight. since it is the only app with "MyDeveloperName" on the phone, if users goe back to VPN & device management screen, no app or developer will be present. user downloads new version of the app. If taps directly on the icon there is a system alert with says the developer must be trusted. a this point in settings > general > VPN & device management you can find a line with developer name, tapping on it we find a screen where user finds a white button with BLUE message "authorize MyDeveloperName" and follows procedure. My issue is that some users get following different behavior, and I do not understand why: ❌ tapping on downloaded app icon: no alert, but app tries to start then crashes. ❌ going in VPN & device management screen there is only RED write button "delete app" in both paths, working and not working, the app results "verified" in VPN & device management screen (Apple says old authorizations are preserved.)

I created a provisional profile from apple developer portal for my iOS app. The expiry date shown in the profile is 21-April 2026. However, when I build the app with this provisional profile the expiry date shown in the app is 11 Dec, 2025. My iOS distribution certificate expires only in November 2026. I see a embeded.mobileprovision profile inside the app, and it has an expiry of 11-Dec-2025. I did a clean build,, cleared unnecessary profiles from profile folder, created a new provisional profile and tried, but nothing seems help. We have a few apps, and no other app has this issue. We do annual release of all apps together for provisional profile renewal. As this app expiry is different, it will cause lot of difficulty for us next year. Will you please help me to resolve this issue? Thanks.

Hello, I have implemented my virtual meeting extension and my application shows no issues in the calendar application, with a join button displayed. Everything is great!. However, with the help of EKEventEditViewController and EKEvent instances, when creating an event from the main target of the application using EventKitUI, the event will not be displayed as a virtual meeting. I have seen that other applications like Zoom have already implemented this, and I find it difficult to find relevant documentation on how to link events created by the program to virtual meetings. How do I set an event as a meeting when I want to add it to the main program? In addition, the function in the VirtualConferenceProvider.swift file of the extension program fetchVirtualConference(identifier: EKVirtualConferenceRoomTypeIdentifier, completionHandler: @escaping (EKVirtualConferenceDescriptor?, (any Error)? ）->Void) How are the parameters in this function obtained? It's impossible for every conference related link to be the same

Hello everyone, I’m looking for some clarity from the community regarding eligibility for the Swift Student Challenge 2026, particularly for students taking a gap year in India. I graduated from high school (Class XII, CBSE – India) in May 2025. After graduating, I chose to take a gap year to prepare for competitive entrance examinations in India, with the goal of pursuing Computer Science / Engineering. I’ll be applying to accredited universities for programs starting in mid-2026, and I’m not currently enrolled in a college. My question: The eligibility guidelines state that high school graduates must have graduated within the past 6 months and must be awaiting acceptance or have received acceptance to an accredited institution. Since the submission deadline is February 28, 2026, my graduation would be about 9 months prior, which puts me in a gray area. Has anyone here participated in, or seen others participate in, the Swift Student Challenge while taking a gap year and preparing for university entrance exams? Is there any known flexibility or precedent for students in this situation? I’ve been following the Swift Student Challenge since 2023 and would really love to participate if I’m eligible. Any insights or experiences would be greatly appreciated. Thanks!

We install two in-house apps. The first app is installed using the standard in-house method, while the second app is installed via MDM commands. Both apps share the same Team ID and use Keychain sharing to exchange data. However, when the MDM profile is deleted and the second app is removed, the first app intermittently encounters issues and does not function properly. However, when the MDM mobileconfig is reinstalled and the second app is installed again, the first app that was not functioning starts working properly. We have thoroughly reviewed the logs but have not been able to find a solution. Your assistance would be greatly appreciated. We have extracted and attached the device logs that were generated during the error occurrence. log.log

Hi, I’m an enterprise developer, and we distribute our internal iOS app through a direct download link on our company website (not via App Store or TestFlight). The app is properly signed and works fine on most devices including iPhones and regular iPads. However, on iPad Pro 11-inch (4th generation), the app crashes immediately upon launch when installed via the website. Interestingly, if we install the exact same app via Xcode, it runs without issue on the same device. We also tested a third-party enterprise app called "Taipei On", and it showed the same crash behavior when installed via direct web download on the same iPad model. This leads us to believe the issue may be more widespread or specific to this iPad Pro model or recent iOS versions. Furthermore, some of our users with iPhone 15 devices have started experiencing similar crashes recently, even though they had no issues before. Is this a known issue related to enterprise app distribution or IPA installation behavior on certain devices? Any advice or insight from the Apple team or other developers would be appreciated. Thanks!
