Enterprise App Crashes on Launch on iOS 18.3.2
We have an office application used internally within our enterprise. The Provisioning Profiles (PP) for the app were about to expire, so we updated the PP and released a new version. However, we've encountered an issue where some users did not update their phones in time. After the app expired, they found it unusable and downloaded the new version, but the newly downloaded app also crashes on launch. Restarting the phone does not resolve the issue, and this primarily occurs on iOS 18.3.2. What could be the cause of this problem, and how should we address it?

After the Provisioning Profile expires, application cannot be used after reinstallation
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.

app crashes, but it works normally when another app is installed through MDM.
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

App Profile Expires Earlier than Provisional Profile
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.

Enterprise App Crashes on iPad Pro (4th Gen, 11") When Installed via Web
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!

Guidance on Integrating with Apple GSX API
Hello all, I’m hoping someone here has gone through the process of integrating an ERP system with the Apple GSX API and can offer some guidance. We’re currently working with an AASP who asked us to integrate our ERP with the Apple GSX API. It’s the first time for both of us, and we’re a bit stuck on how to properly get started. The AASP contacted their regional manager, who confirmed that an NDA and an Apple Developer Account would be necessary. However, he hasn’t handled this type of integration before and is still seeking internal guidance. That was a few months ago, and due to his workload, the AASP hasn’t heard back from him yet. Meanwhile, we’ve already enrolled in the Apple Developer Program and opened a support case, but we’ve been redirected to the forums since our case goes beyond standard support. So now we’re trying to understand: What steps need to be completed by the AASP? What are the steps we, as the ERP provider, need to take in order to receive API access? Are there any specific documents, applications, or technical requirements we should prepare in advance? We’d really appreciate any guidance or insight from others who have gone through this process — or even partial answers to help us move forward. Thanks in advance for your time!

Enterprise App Installation Fails on iOS 18.5 with Integrity Error
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."

Thank you in advance for your assistance.

RCS firewall domains & ports
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!

How to change the expiry date of existing iOS Distribution (In-House) Certificate
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

Intune Auto-Update Issue Following Xamarin Project Migration
We're currently facing an issue with Intune not automatically updating/downloading the updated build/app to end-user ios devices. It's worth noting that we've recently migrated the Xamarin project to a .NET-style SDK in this version. Previously, the app used to update automatically without any problems. We'd appreciate it if you could help us understand what might be causing this issue.

CNContact instantMessage field duplicates after serializaiton/deserialization
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!

We have several apps that our business uses to connect to internal private HTTP sites. We noticed in IOS 18.3 we are getting SSL errors to the web server and noticed the issue in the Chrome Browser as well. Our team is looking at the Application Transport Security layer exceptions in our apps Info.Plist. We do notice the browser forcing HTTPS. Any insight on what could be the issue?

Timed Subscriptions availability
Hello, Is it acceptable to have subscriptions that are available for limited times on the app, for example I would like only 100 new paid subscription purchases on the App every month. When the 100 quota is finished, users might see something like "Check back next month". This is to control growth and marketing purposes.
