Hello folks, I stumbled upon a weird CNContact serialization problem. I use the Contacts framework to update the AIM field, which is one of the instantMessageAddresses within a single Contact. Here is the simplified code I used: func updateAIMFieldOn(contact: CNContact, aimValue: String) { do { guard let mutableContact = contact.mutableCopy() as? CNMutableContact else { logger.error("[CM] Couldn't update contact with aim \(aimValue)") return } var updatedAddresses = mutableContact.instantMessageAddresses updatedAddresses.append(CNLabeledValue(label: "", value: CNInstantMessageAddress(username: aimValue, service: CNInstantMessageServiceAIM))) mutableContact.instantMessageAddresses = updatedAddresses let saveRequest = CNSaveRequest() saveRequest.update(mutableContact) try CNContactStore().execute(saveRequest) logger.verbose("Contact's AIM updated successfully!") } catch { logger.error("Couldn't update contact") } } And after serializing the contact to data, and then deserializing, the contact got two AIM fields with the same value: X-AIM;type=pref:some:part:of_my_aim_value IMPP;X-SERVICE-TYPE=AIM;type=pref:some:part:of_my_aim_value Why does it work in this manner? Is it possible that ":" char causes that? Format of my aim username is {some:part:of_my_aim_value}. I didn't find any information in the docs. Thanks!

Hi Apple Community, At WWDC25, introduced a native device migration feature with iOS/macOS 26 and Apple Business Manager that promises seamless migration from one MDM to another without wiping devices or manual re-enrollment. That said, while testing this in iOS/macOS 26 beta, we ran into an issue: the Wi-Fi settings deployed by the old MDM aren’t retained during the migration. This means devices lose Wi-Fi connectivity partway through, and users have to manually reconnect before the migration to the new MDM can continue. This interrupts what should be a smooth, hands-off process. We wanted to ask if this is a known issue or limitation with the current beta? Are there any recommended ways to avoid losing Wi-Fi profiles during this migration window? Will this improve in future updates so that the Wi-Fi connection is preserved or seamlessly handed off to the new MDM? Any tips, workarounds, or official guidance Apple can share on best practices for handling Wi-Fi profiles during ABM-native device migrations would be hugely appreciated. Added Feedback with FeedBackAssistant ID : FB20150763 Thanks in advance.

Hello, I have an Apple Developer Enterprise account, and Apple Support has already enabled MDM for my account. I successfully downloaded and installed my MDM Vendor Certificate (it shows up in Keychain as MDM Vendor: [My Company Name] with its private key). Here’s what I’ve done so far: Exported the Vendor Certificate + private key as a .p12, then converted to .pem and .key using OpenSSL. Generated an unsigned CSR with CN=com.apple.mgmt.External. using OpenSSL. Attempted to sign the CSR using: my Vendor certificate the Vendor private key Apple Worldwide Developer Relations (WWDR) intermediate certificate OpenSSL smime -sign command with DER output Problem: Every time I try to upload the vendor-signed CSR to the Apple Push Certificates Portal, I get an error (CSR rejected). Sometimes OpenSSL even fails with “unable to load certificates” depending on how the WWDR certificate is included. My Questions: What is the correct OpenSSL command and certificate chain Apple expects for signing the CSR? Do I need to include any additional intermediates besides WWDR? Is there an official Apple reference example for generating the vendor-signed CSR that the Push Certificates Portal will accept? Any guidance from the community (or someone who has successfully done this end-to-end) would be greatly appreciated. Thank you, Sergio Sanchez

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? For the fortigate and palo alto firewalls I need specifics: domains (or subdomains) that need whitelisting and the ports involved. Any official or community-sourced info would be super helpful—thanks in advance!

Hello, I am running into a bit of an issue with the Screen Timeout/Screen Lock setting and would like some clarification on. First for a bit of context, I am enrolling personal iOS devices 18.0+ into the company MDM (Intune) with Account Driven User Enrollment. We are trying to set a screen timeout of 5 minutes and immediately after it asks for the passcode on the device, though this setting is not being applied and the device timeout setting can be set as "Never" on the user's end. This is a big security risk for the company I work for and and the issue with being HIPAA compliant. According to the Microsoft Intune Support, "In iOS 18, when using Account-Driven User Enrollment for BYOD (Bring Your Own Device) scenarios, the screen lock timeout setting is indeed marked as “Not Applicable”. This is because Apple’s privacy-preserving model for personal devices restricts administrative control over system-level settings like screen lock or idle timeout." I am needing clarification on the item mentioned from Microsoft Intune Support and if this setting is no longer able to be applied from the MDM with devices enrolled with Account Driven User Enrollment?

Hello world! First post here. Developing my first app. It primarily targets supervised and MDM managed devices. A few questions: For supervised devices, is serial number available? I want to get the number and use it for app auto activation Is MDM required for supervised devices? Or, as long as a device is enrolled through Apple Business Manager? Which capacity shall I request for the app? Thanks so much!

My company signed the application with enterprise certificate, the Provisioning Profile expired on March 20, 2025. Some iPhones didn't update the application before the expiration. We have update the Provisioning Profile and repackaged application. However, these iPhones still can't use the application after reinstalling the new ipa. After opening the application, the screen is blank and then flashes back without any error prompt. Restarting iPhone didn't help.

New devices coming to this year is named as iPhone 17 .... Why we care not going for iPhone 26. .... ? if it is named as iPhone 26... in line with new version policy, it will be easier to relate in all perspective.

Hello everyone, I recently changed the phone number associated with my Apple ID (about 4 days ago), but I’m still receiving the two-factor authentication verification codes on my old number instead of the new one. Has anyone experienced this? Is there a delay on Apple’s side, or is there something else I need to do to complete the update?

I have created a configuration profile which basically just turns off notifications for Shortcuts app but I am unable to install it on my iPhone as I am getting the following error “This profile can be installed on a supervised device only” can someone please help me with this? Would also appreciate if you have another way to turn off shortcuts notifications permanently since when I turn it off via screen time it keeps turning itself ON every couple of days.

On google it's showing with in 24 for developer enrollment now waiting for 4th day no update at all

Hey folks, I work as a software development consultant. We develop enterprise applications for our clients, and the apps we create are usually for internal use. We've ran into a bit of a conundrum with a client who doesn't have their own Apple Enterprise account, and neither do we as we don't meet the criteria, but they're wanting to distribute an application we've built for them via their own MDM software. We are not entirely sure how to provide them with a distribution ready .ipa file that isn't AdHoc and will be recognized as a secure app. We've looked into generating a Developer ID provisioning profile and accompanying cert, however we're running into a problem where the platform of our app (iOS) doesn't match the platform required by the Developer ID profile (macOS). I've also come across the idea of resigning an .ipa, but again, the client doesn't have a Apple Developer account and expects the working .ipa to be included in the service rendered. Any suggestions or advice or documentation around the subject would be greatly appreciated. Thanks, Ale

Hi all, I'm implementing Intune MAM to secure applications on iOS. However, I need my users to be able to save files (e.g. attachments in an email in the Outlook app) to iOS Files. To do so, I'm trying to put Files in exception of my Intune MAM policy and I need to obtain the Files "CFBundleURLSchemes" value from the info.plist file of the Files app. I'm not able to get that information. Are any of you able to get that somehow? Thanks!

Hello, this may not be the correct place to ask this question so I apologize in advance if this is the case. We are currently having some issues when attempting to restore device back ups via iCloud that where previously enrolled to our MDM solution, as upon the restore no app data seems to be persisted over (we have tested restoring the backup on the same device and we have been able to have data persist between wipes) On the initial device we have ensured that the restrictions allowCloudKeychainSync allowManagedAppsCloudSync are set to true, and can see that the initial devices back up has the app data backed up, yet despite this data is not persisted when restoring from back up on a new device. On the device where the back up was initially done when restoring the applications are applied but indicated that they must be re-installed via our management console, once the app has been uninstalled and reinstalled the old data does show up, when applied to the new device our mdm solution pushes down the app.managed config but the device treats it as a new install. Could this possibly be due to us using Device Licensing when assigning apps? Or is it due to the intial device only performing a token update request when restoring and the new device going through the entire checkin proccess? Both devices are provisioned via DEP, and applications where assigned initially via VPP Any insight on this would be useful (For reference this is an MDM solution of our own making so we are attempting to sus out if there is a configuration issue we could be overlooking).

I am a developer distributing an enterprise app. Recently, some users have intermittently encountered an error message on iOS 18.5 stating: "Unable to install this app because its integrity could not be verified." While the issue could not be reproduced on iPhone 15 / iOS 18.5, we have received reports that it does occur on the following devices: iPhone 14 / iOS 18.5, iPhone 14 Pro / iOS 18.5, iPhone 14 Plus / iOS 18.5, iPhone 16 Pro Max / iOS 18.5, Are there any known issues or recommended solutions regarding this behavior? Thank you in advance for your assistance.

Hello, this may not be the correct place to ask this question so I apologize in advance if this is the case. I am currently running into two specifc issues while continuing to implement the app.managed configuration which are quite frustrating and I will detail them below Unlike MDM where an application could be "reinstalled", by sending an install application command down for the same app DM does not have a similar mechanism which causes some issues as (while inconsistent) devices do not always respect the configuration sent down, and will not begin downloading VPP applications. They can be seen in the configuration when checking under VPN & Device Management but they do not return on a status report, alternatively and app will "install" but will have a cloud symbol next to it requiring a download (which I believe would be impossible on supervised devices without apple accounts/have restricted apple accounts associated to them). These apps are also reported incorrectly, as they return a managed response while being inaccessible. Both of these issues are solved by removing and reinstall applications (occasionally). Is there any easier way to trigger a re-install or is this the only way to trigger this? The Version element that can be optionally sent down does not seem to work (or if it does, does so inconsistently). A device will very happily download the application initially with the version element present, though when we detect an updated external ID from the VPP program and send down an updated configuration devices behave unexpectedly. Some have ignored it, some have responded back that a download has begun (with no download taking place and the application clearly still being the initial installed version as can be see in the apps page) or it just works, but there is not consistency. I realize a new UpdateBehavior object has been added to possibly handle this, but it is only supported in iOS 26 and above and there are plenty of people who do not have phones that can upgrade that far. Are there alternative ways to enforce an application update other than uninstalling and reinstalling the application without the version (or will sending down a config without a version after one was originally pinned force it to update to latest?) Kind Regards

We are trying the renewal the apple Enterprise program. It asks set of questions after that it shows the below message "Thank you for your request to renew your membership in the Apple Developer Enterprise Program. We’ll review your submission and get back to you shortly to let you know if we can process the renewal or if another program better serves your organization’s needs." We have submitted for review for over two months now. During these two months, we have contacted the official customer service multiple times, only to be told to wait for news. Now, with only a few days left, The status hasn't changed, neither approved nor rejected，what should we do？This account is very important to our company. Thank you

On iOS 26, if in "Single App Mode", the device gets stuck on the lock screen. Devices are configured in SAM (kiosk mode), without a PIN requirement. Since updating to iPadOS 26, every single device that locks (goes to sleep) becomes completely unresponsive at the lock screen. Touch input does not work. The only way to regain access is to reboot the device, which will boot to the SAM app, but then lock again if it goes to sleep. Related discussion in the public forums.

We are implementing the Return to Service (RTS) with App Preservation flow. During testing, we were able to successfully fetch the Bootstrap Token as part of the ADE enrollment process. However, when attempting to initiate the Return to Service command with App Preservation enabled, the following error was returned: [ { "ErrorCode": 12089, "ErrorDomain": "MDMErrorDomain", "LocalizedDescription": "Could not erase device.", "USEnglishDescription": "Could not erase device." }, { "ErrorCode": 66002, "ErrorDomain": "MDMBootstrapTokenErrorDomain", "LocalizedDescription": "Failed to generate LAContext for bootstrap token", "USEnglishDescription": "Failed to generate LAContext for bootstrap token" } ] Below is the sample request (with dummy data).
