Can MailKit be used to manage existing messages?
I would like to create a MailKit extension that will allow me to manage my existing messages. I would like to move them around form folder to folder and reqad and update their headers to store some metadata that will be used by the extension. Looking at the documentation for MailKit suggests that I can only implement 4 types of handlers (content blocker, action handler, compose handler and security handler). I can’t see anything in the docs about being able to get a list of messages in the inbox and manipulate them. Am I missing something? I’d love to hear from someone who knows more about this topic before I get into a dead-end rabbit hole. cheers, -tomek

How to open parent app from `ShieldActionDelegate`
Hello, I think it is quite a common use-case to open the parent app that owns the ShieldActionDelegate when the user selects an action in the Shield. There are only three options available that we can do in response to an action: ShieldActionResponse.none ShieldActionResponse.close ShieldActionResponse.defer It would be great if this new one would be added as well: ShieldActionResponse.openParentApp While finding a workaround for now, the problem is that the ShieldActionDelegate is not a normal app extension. That means, normal tricks do not work to open the parent app from here. For example, UIApplication.shared.open(url) does not work because we can’t access UIApplication from the ShieldActionDelegate unfortunately. NSExtensionContext is also not available in the ShieldActionDelegate unfortunately, so that’s also not possible. There are apps however, that managed to find a workaround, in my research I stumbled across these two: https://apps.apple.com/de/app/applocker-passcode-lock-apps/id1132845904?l=en-GB https://apps.apple.com/us/app/app-lock/id6448239603 Please find a screen recording (gif) attached. Their workaround is 100% what I’m looking for, so there MUST be a way to do so that is compliant with the App Store guidelines (after all, the apps are available on the App Store!). I had documented my feature request more than 2 years ago in this radar as well: FB10393561

BadDeviceToken Error in Live Activities
Hello everyone, I’m currently receiving feedback from clients in a production environment who are encountering a BadDeviceToken error with Live Activities, which is preventing their states from updating. However, for other clients, the token is working fine and everything functions as expected. I’m collaborating with the back-end developers to gather more information about this issue, but the only log message we’re seeing is: Failed to send a push, APNS reported an error: BadDeviceToken I would greatly appreciate it if anyone could provide some insight or information on how to resolve this issue.

iOS Message Filter Extension - deferQueryRequestToNetwork(completion:) error
iOS Message Filter Extension - deferQueryRequestToNetwork(completion:) error I made a test app using the iOS App template and added a target using the Message Filter Extension template which invokes deferQueryRequestToNetwork(completion:) when receiving an SMS. The app and the extension have same "Associated Domains Capabilities" with "messagefilter" pointing to a server which receives query requests and returns proper responses. The extension has the "ILMessageFilterExtensionNetworkURL" key in Info.plist file which specifies the server URL. deferQueryRequestToNetwork(completion:) throws a com.apple.calls.messagefilter error which reads "Extension's containing app (appID ) unauthorized to defer requests to host "

How to find renamed app using old name in Spotlight?
We are planning on renaming our app. The new name is not like the current name. It will be renamed in the App Store as well as the App display name. Yet, we still want new and existing users to be able to find the app by using the old name in search/spotlight under iOS. A great example of this is entering Twitter to find the X app and it shows up in the App section in the Spotlight search. Are there any guidelines, settings, or tricks for doing this? Some have suggested adding a Spotlight search term but that will not have it show up in the App section I fear.

Compression LZMA2 (SWCompression)
Hi everyone, I am trying to compress my data using LZMA2 with the help of CocoaPods. Here are the steps I followed to achieve LZMA2 compression: Added the pod 'SWCompression', '~> 4.8' dependency to my Podfile and installed the pod using the terminal. When I try to compress the data using LZMA2, I am unable to do so because in SWCompression, LZMA2 compression is marked as TBD (To Be Determined). Here is the current status of SWCompression: Deflate BZip2 LZMA/LZMA2 LZ4 Decompression ✅ ✅ ✅ ✅ Compression ✅ ✅ TBD ✅ Zlib GZip XZ ZIP TAR 7-Zip Read ✅ ✅ ✅ ✅ ✅ ✅ Write ✅ ✅ TBD TBD ✅ TBD Since LZMA2 compression is still marked as TBD, is there any other way to achieve LZMA2 compression for my data in SwiftUI?

iOS Action and Share Extensions disappear for users
Several users have reported that my iOS Action and Share Extensions is not visible. Now one of the TestFlight users has reported the same. Notice this user has been using the app for one year, so they know how to use it. Doing FaceTime and them sharing the screen, we have tried: Deleting app and downloading from App Store Deleting app, turning device off (call was off) and turning it on, downloading from App Store Deleting app, turning device off (call was off) and turning it on, downloading from TestFlight They can open the app, they just do not see the extensions. I would have thought it was the activation rules inside of the InfoPlist, but they are the same for all users and my other testers are not facing the issue. Device is iPhone 16 Pro, iOS 18.1 What other steps could I follow? What other information could I gather to fix this?

Applinks failing
Hello, We're facing an issue with app links failing and falling back to browser website journeys. Our apple-app-site-association file is hosted publicly and the app to app journeys have been working correctly up to very recently - we are trying to identify any potential network infra changes that could have impacted the Apple CDN being able to retrieve the apple-app-site-association file. We can see in the iPhone OS logs that the links cannot be verified by the swcd process, and using the app-site-association.cdn-apple.com/a/v1 api via curl can also see the CDN has no record of the AASA file. Due to the traffic being SSL and to a high volume enterprise site it is difficult for use to trace activity through anything other that the source IPs - we cannot filter on user-agent for "AASA-Bot/1.0.0" as breaking the SSL would be impactful due to the load. Is it possible to get a network range used by the Apple CDN to retrieve the AASA file as this would help us identify potential blocking behaviour? Thank you.

Live Caller ID on iOS does not work - client requests not reaching backend
I'm reaching out to see if anyone else is experiencing issues with the Live Caller ID feature on iOS. We recently encountered a problem where the feature stopped working entirely. Here's a brief overview of the situation: We were monitoring test traffic on our backend and noticed everything came to a halt around 1:00 AM UTC on November 15th. After this time, any attempts to reach our backend through calls failed completely. I tested this across multiple devices running iOS 18.2 and iOS 18.0. I used both TestFlight builds and development builds via Xcode, which should communicate directly with our backend. I experienced the problem on our main application as well as a dedicated test app. To troubleshoot further, I even set up a local server on localhost and tried directing requests there, but the requests did not reach the local server when a call was received. Further debugging in Console.app revealed the following error: identity request returned error: Error Domain=com.apple.CipherML Code=400 "Error Domain=com.apple.CipherML Code=401 "Unable to request data by keywords batch: failed to fetch token issuer directory" However, when I manually tried to hit our server endpoint using curl, the request successfully reached the server: curl https://our_server/something hb_method=GET hb_uri=/something [Hummingbird] Request -- log on backend This suggests that while our backend is responsive, the requests from the iOS client side are simply not being initiated.

Doesn't work WidgetCenter.shared.reloadAllTimelines() with WKRefreshBackgroundTask
After updating to watchOS 11.1, updates using WidgetCenter.shared.reloadAllTimelines() in WKRefreshBackgroundTask stopped working. When the background task is triggered, it gets data from the phone and updates the WidgetKit complications. But now the refresh call WidgetCenter.shared.reloadAllTimelines() does not update the complications.

FamilyActivitySelection tokens are invalid for other members in family sharing network
I'm currently working with the FamilyControls API and testing my app on two different devices. Both apps are in the same family-sharing network with one phone being the owner of the network (I'll call this A) and the other one being an adult in the network(I'll call this B). When device A picks apps using the FamilyActivityPicker, it shares that selection with device B (via encoding, sending over network, and decoding on device B). However, interacting with the token (displaying it, using it in shield) throws an error saying the token is null. From the documentation, I thought every token would be the same across all devices in the family sharing network. So my question: How do I send the FamilyActivitySelection from A to B and have the tokens still be functional? Does this functionality only work if A is a "parent" and B is a "child" in the family sharing network? Also, side note: If I reverse the process and send the tokens from B to A. Interacting with the token works exactly as expected. For some reason, it's only going from A to B where it doesn't work.

Finder File Previews lock files on SMB shares
I've developed a new Quicklook data-based preview extension for a custom file type that generates an image preview of the file. I previously used a Quick Look generator plug-in but support for it was deprecated and now removed in macOS Sequoia. My app opens files using a open(url.path, O_RDWR | O_NONBLOCK | O_EXLOCK) call. The locking flags are used to prevent other clients from writing the file if it's already open. I discovered that when Finder is showing the “large” file previews (such as when in column or gallery modes) from a SMB share, the open call fails with EWOULDBLOCK as if the file is locked. It does work just fine on local files. Opening with O_SHLOCK also has the issue. Surprisingly it does work just fine for previews that return Plain Text data instead of Image data. Using the lsof command, it seems like the Quicklook process has some kind of lock on the file. This is the output of the lsof command: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE QuickLook 48487 XXXX txt REG 1,15 125000611 3161369 Attached is a test project that tries a few different opening and locking functions. It also includes a test file and a sample image preview extension that displays a red square. When everything is working, regular console messages show the progress of the tests. When the file is on a SMB share and selected in Finder Gallery mode, the open test will fail with a fault message in the console. Notably, locking with flock works, which is weird because it should have similar semantics according to the man page for open(2). Filed this as FB15051186

App Intent title and other localized strings not showing correctly in Shortcuts app on macOS 15
I rarely use the Shortcuts app, so it took me a while to notice that my app's app intents all show incorrectly on macOS 15. On macOS 14 and 13, they used to show correctly, but now it seems that all localized strings show the key rather than the localized value. @available(iOS 16.0, macOS 13.0, *) struct MyAppIntent: AppIntent { static let title = LocalizedStringResource("key1", comment: "") static let description = IntentDescription(LocalizedStringResource("key2", comment: "")) ... } In Localizable.xcstrings file I have defined all the strings, for instance I have associated key1 with the value Title, but while the Shortcuts app used to display Title, it now displays key1. Is this a known issue or did something change in macOS 15 that would require me to update something?

Basic app intent always showing error in Shortcuts app "The action could not run because an internal error occurred."
I have a very basic App Intent extension in my macOS app that does nothing than accepting two parameters, but running it in Shortcuts always produces the error "The action “Compare” could not run because an internal error occurred.". What am I doing wrong? struct CompareIntent: AppIntent { static let title = LocalizedStringResource("intent.compare.title") static let description = IntentDescription("intent.compare.description") static let openAppWhenRun = true @Parameter(title: "intent.compare.parameter.original") var original: String @Parameter(title: "intent.compare.parameter.modified") var modified: String func perform() async throws -> some IntentResult { return .result() } }
