DataCloneError in MapKit JS Worker when posting non-detachable ArrayBuffers (Chrome ≥120)
Since integrating MapKit JS, we’ve begun receiving production error reports with the following message: Uncaught DataCloneError: Failed to execute 'postMessage' on 'DedicatedWorkerGlobalScope': ArrayBuffer is not detachable and could not be cloned. It appears that MapKit JS’s internal worker occasionally calls postMessage() with an ArrayBuffer that cannot be detached under Chrome 120+. This causes the structured clone to fail and the error surfaces uncaught from within the worker. MapKit JS Version: 5.79.109 Browser: Chrome 120.0+ OS: Windows 10 Is this a known issue with MapKit JS? If so, are there recommended workarounds or planned fixes?

Reply to Question about including all project classes in ofClasses parameter when using NSKeyedUnarchiver.unarchivedObject(ofClasses:from:)
Hello, Thank you for your detailed response to my previous question. I understand that including all classes used within the app in the ofClasses parameter is not the correct pattern. Situation Update: Following your advice, I tested by including only the root object's class in ofClasses. Class X contains nested objects Y and Z. // Including only root object and some nested objects NSKeyedUnarchiver.unarchivedObject(ofClasses: [X.self, Y.self], from: data) Problem Encountered: However, I encountered the following error: Error Domain=NSCocoaErrorDomain Code=4864 value for key 'anotherNestedObject' was of unexpected class 'Z'. Allowed classes are: { 'X', 'Y' } The error was only resolved when I included class Z in ofClasses as well. Current Implementation Verification: Class X properly implements NSSecureCoding In the init(coder:) method, it individually decodes nested objects using coder.decodeObject(ofClass: Y.self, forKey: nestedObject) and coder.decodeObject(ofClass: Z.self, forKey: anotherNestedOb

blockedByFilter = .specific(domains) does not work on Safari
Hi there, I have a popular open source app called Foqos. What I'm finding in iOS 26 (might even effect older versions) is that when using the webcontent api within Managed settings as the following: store.webContent.blockedByFilter = .specific(domains) It doesn't work on Safari, but does work on third party applications like chrome, firefox, etc. But when using the all and exception enum like the following store.webContent.blockedByFilter = .all(except: domains) This does work on Safari This is pretty inconsistent behavior of the API and should be fixed to match the documentation. Documentation does not mention anything about Safari limitations Again source code is open: https://github.com/awaseem/foqos You can run the app yourself and find the same issues. Is anyone else experiencing this?

Reply to ScrollView + LazyVStack + dynamic height views cause scroll glitches on iOS 26
Hi Albert, Thanks for your response and for taking the time to look into this. You’re right — in my original post the SquareView struct was omitted. I’ve now prepared a complete and minimal Xcode project including both versions (fixed-size and dynamic text). You can find it here: https://github.com/Sawyer-815/infinite-scroll The project builds without warnings using Xcode 26.0.1 and reproduces the issue consistently on iOS 26 simulators (iPhone 17 Pro). You can toggle between Fixed size and Dynamic size using the segmented control to compare behaviors. Let me know if you need any additional details or if there’s a better way to structure the test. Thanks again for your time, Sawyer

The App Store Connect team refused to communicate and Termination my account.
I submitted a puzzle app called “Anime Jigsaw” to App Store Connect. The App Store Connect team initially rejected the app due to minor errors. I then fixed the errors and resubmitted it, but this time they said it violated “Guideline 4.1 - Design - Copycats” and that I didn't write the code. I responded that I wrote the code and could prove it. They rejected it again, citing Guideline 4.1 - Design - Copycats,“ and I explained that my app was different from other puzzle apps because you solve puzzles while listening to Lo-Fi music. But this time, they issued a ”Pending Termination Notice“ and started saying ”Evidence of Dishonest or Fraudulent Activity. I am definitely not a scammer. I am trying to communicate with the App Store Connect team, but they are trying to close my account and label it as “Fraudulent Activity.” Why are you doing this? How can I resolve this? My account will be closed in 30 days, and I can't communicate with anyone. Team ID: 93LGGK4LG4 Apple ID: 6751961511 Please App

Reply to ScrollView + LazyVStack + dynamic height views cause scroll glitches on iOS 26
Thanks for the post and thanks for the code. I consistently ask for comprehensive and focused sample projects, as I occasionally encounter missing classes when retrieving the code. In this instance, it appears that ,in the working version, the SquareView object is not defined? So I can't check the not working version. Will be great to have a focused sample with both versions to compare them. Could you kindly provide the focused and simplified project so that individuals can download and verify the issue? If so, please share a link to your test project. That'll help us better understand what's going on. If you're not familiar with preparing a test project, take a look at Creating a test project. Thanks, Albert Pascual

Why are system reserved files consuming half of my storage?
I am constantly running out of storage on my iPhone 16 Pro. I keep having to move my photos and videos to my laptop and delete them from my phone, and I’m constantly needing to offload apps and manually clear caches in some apps to free up storage. I finally got sick of having this cycle every two weeks so looked into it more closely. I’m finding that iOS consumes 32 GB, and then another system reserve category is consuming an additional 23 GB. Meaning the system reserved files are consuming half of the storage on this phone and effectively making it a 64 GB model. I understand the system will need to consume some capacity for itself and that iOS is getting larger, but nearly 50% of the capacity of the phone is insane. Looking closer into the categories, I’m seeing that iOS has taken it upon itself to also permanently provision 10% of the storage capacity for reserve update space. Already another instance of “why am I having to lose so much of my functional capacity to an occasional process?” but I can unders
