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." 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.

Proctoring tools
My institution uses Blackboard and iPads to conduct assessments, and I’m trying to find some proctoring tools. Students conduct the assessments directly on Blackboard using either Safari or Chrome. I know that Apple has a function that does EXACTLY what I’m looking for, but from what I understand, this function has to be made available by Safari or Chrome: https://developer.apple.com/documentation/automaticassessmentconfiguration I don’t know whether either of these two browsers have this function enabled, and whether it can be switched on and off for custom-made Blackboard assessments. Is this a possibility? Are there other options? I know Blackboard offers built-in and third-party proctoring, but contacting them is difficult, and my company does not give me the appropriate authority to speak directly with Blackboard. So, I’m not able to find out about the feasibility, costs, etc. of this option. Any help would be greatly appreciated.

I'm trying to get the "App and Book Information" of the custom app, but the result is empty.
I'm looking at the Apple official document below and getting the app's information. https://developer.apple.com/documentation/devicemanagement/getting-app-and-book-information-legacy However, I couldn't get the custom app's information for a few days ago. The result item is empty. This is a URL that is normally viewed. https://uclient-api.itunes.apple.com/WebObjects/MZStorePlatform.woa/wa/lookup?version=2&p=mdm-lockup&caller=MDM&platform=volumestore&cc=jp&id=1202716089 This is the URL that gives an empty response to the result. https://uclient-api.itunes.apple.com/WebObjects/MZStorePlatform.woa/wa/lookup?version=2&p=mdm-lockup&caller=MDM&platform=volumestore&cc=jp&id=1556411142 In ABM/ASM, the number of applications used and the number of available applications are all viewed normally. Is there anything else I can check? Please reply. Thank you.

How to install a configuration profile created through Apple Configurator or imazing profile editor on an unsupervised iPhone?
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.

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!

I would like to work with developers I believe I have rights to share.
Three months ago I molded a mold program. I believe could be tweaked and tried unlined zero code. swear. anyway I would like to scale with some people if I can go to commercial area code phoned series and calls.and if I have rights. but my next moves for them. on iOS I think they should have a seri settings. where they can call seri.on settings, and it jump many codes-and navigation is hard. plus I think seri can help in settings expecially since seri settings is verbal drop. if the words fit or are similar it cues goes to but you have to hard call the switch.so there’s no hey no Sami where you setting no Sammy right I think it could skip cauldron and everything verbally either. Seri settings I think iOS should try it.

Can't execute Software Update:Enforcement:Specific on ADE Macbook
I have enrolled a macbook through ADE to Apple School Manager and register it to the MDM service. Upon sending the initial DeclarativeManagement payload, the device return the client capabilities as below: "supported-versions": [ "1.0.0" ], "supported-payloads": { "declarations": { "activations": [ "com.apple.activation.simple" ], "assets": [ "com.apple.asset.credential.acme", "com.apple.asset.credential.certificate", "com.apple.asset.credential.identity", "com.apple.asset.credential.scep", "com.apple.asset.credential.userpassword", "com.apple.asset.data", "com.apple.asset.useridentity" ], "configurations": [ "com.apple.configuration.account.caldav", "com.apple.configuration.account.carddav", "com.apple.configuration.account.exchange", "com.apple.configuration.account.google", "com.apple.configuration.account.ldap", "com.apple.configuration.account.mail", "com.apple.configuration.account.subscribed-calendar", "com.apple.configuration.legacy", "com.apple.configuration.legacy.interactive", "com.apple.configuration.management.status-subscriptions", "com.apple.configuration.management.test", "com.apple.configuration.math.settings", "com.apple.configuration.passcode.settings", "com.apple.configuration.safari.extensions.settings", "com.apple.configuration.screensharing.connection", "com.apple.configuration.screensharing.connection.group", "com.apple.configuration.security.certificate", "com.apple.configuration.security.identity", "com.apple.configuration.security.passkey.attestation" ], "management": [ "com.apple.management.organization-info", "com.apple.management.properties", "com.apple.management.server-capabilities" ] }, "status-items": [ "account.list.caldav", "account.list.carddav", "account.list.exchange", "account.list.google", "account.list.ldap", "account.list.mail.incoming", "account.list.mail.outgoing", "account.list.subscribed-calendar", "device.identifier.serial-number", "device.identifier.udid", "device.model.family", "device.model.identifier", "device.model.marketing-name", "device.model.number", "device.operating-system.build-version", "device.operating-system.family", "device.operating-system.marketing-name", "device.operating-system.supplemental.build-version", "device.operating-system.supplemental.extra-version", "device.operating-system.version", "management.client-capabilities", "management.declarations", "screensharing.connection.group.unresolved-connection", "security.certificate.list", "test.array-value", "test.boolean-value", "test.dictionary-value", "test.error-value", "test.integer-value", "test.real-value", "test.string-value" ] }, "supported-features": { } } }, com.apple.configuration.softwareupdate.enforcement.specific couldn't be found. The macbook current OS version is 15.5 and it's supervised so looking at this, I assume it should include the Software Update:Enforcement:Specific capability? https://github.com/apple/device-management/blob/release/declarative/declarations/configurations/softwareupdate.enforcement.specific.yaml When I tried sending the payload to the device anyway the valid status is unknown

[iOS 26.1 beta 2] allowCamera restriction not working properly on both supervised and BYOD devices
Details: Device: iPhone 12 Pro Max System: iOS 26.1 beta 2 Issue Description: When testing MDM device restriction capabilities on iOS 26.1 beta 2, I found that the allowCamera restriction does not work as expected. Observed Behavior: • On a BYOD device: When allowCamera is set to false, the Camera and FaceTime apps disappear from the Home Screen, as expected. However, third-party apps (such as WeChat) can still access the camera and take photos. • On earlier versions (e.g. iOS 26.0.1): Setting allowCamera to false correctly blocks all apps, including third-party apps, from accessing the camera. Initially, I assumed Apple might have changed this restriction behavior so that allowCamera only applies to supervised devices. However, after testing on supervised devices, I found that even there, when allowCamera is set to false, the Camera and FaceTime apps are hidden, but third-party apps can still use the camera. This indicates that the restriction is not functioning correctly in iOS 26.1 beta 2. Expectation: When allowCamera is set to false, all camera access — including third-party apps — should be blocked. Request: Could someone from Apple’s development or MDM team confirm whether this is an expected behavior change or a potential bug in iOS 26.1 beta 2?

Return to Service with App Preservation issue
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). The actual request contained valid values in all fields: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Command</key> <dict> <key>RequestType</key> <string>EraseDevice</string> <key>ReturnToService</key> <dict> <key>Enabled</key> <true /> <key>WiFiProfileData</key> <data>WiFiProfileData</data> <key>BootstrapToken</key> <data>BootstrapTokenValue</data> <key>MDMProfileData</key> <data>MDM Profile Data</data> </dict> </dict> <key>CommandUUID</key> <string>3670</string> </dict> </plist>

Software Update Enforcement Specific
When using the SoftwareUpdateEnforcementSpecific to target an update to iPad OS 18.7.1, will the update be triggered to be downloaded immediately after the iPad has an active Internet connectivity? Or, if the SoftwareUpdateSettingsAutomaticActionsObject download string is set to AlwaysOff, will this mean that the update enforced will not start downloading automatically, but only when the user decides? I am trying to understand how these two can be combined together or if they work independently, as while trying to enforce a specific version, we need to eliminate the possibility to download an iPad OS version using cellular data, as our devices have an eSIM installed and the cost of using that for the iOS updates will be quite high. Maybe there is a setting to only allow the iOS updates to be downloaded via Wi-Fi. Thanks!

Question/Feature Request: String-based Version Specification (x.y.z) for `InstallBehavior.Version` in App:Managed
Hello, I'm currently working on implementing app installation features, referencing the app.managed.yaml declaration on GitHub: https://github.com/apple/device-management/blob/0a4527c5ea21825fd23e08273ccdb9e2302458ce/declarative/declarations/configurations/app.managed.yaml My question pertains to the InstallBehavior.Version key. The current specification indicates its type as <integer>: key: Version title: Version supportedOS: iOS: introduced: '26.0' macOS: introduced: '26.0' visionOS: introduced: '26.0' type: <integer> Is there a way to specify the app version using a string format, such as x.y.z, instead of the integer (App Store External Version Identifier - EVID)? Allowing for a simpler version specification would make app version management through MDM more flexible and efficient. I believe this would significantly streamline the deployment and operation of Apple devices within organizations. Any guidance or consideration for this would be greatly appreciated. Thank you.

in-house app cannot be authorized with iOS 18 new authorization procedure
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.)
