In the public release of iOS 18.4.1 and iPadOS 18.4.1, external input support for keyboards and mice is critically degraded. This issue affects both Apple-branded and third-party HID-compliant devices, over both wired USB-C and Bluetooth.
Tested Hardware:
• iPhone 16 Pro Max (256GB)
• iPad Pro (USB-C, latest gen), last gen iPad as well
Affected Devices:
• Apple Magic Mouse and Keys (wired USB-C/Bluetooth)
• Redragon K580RGBPRO (Bluetooth/wired USB-C)
• Razer Naga V2 Pro (Bluetooth/USB-C)
Symptoms:
• Severe keystroke delay and dropped input
• Modifier keys (Shift, Command, Option) fail intermittently
• Input degrades further with multiple HID devices connected
• Mouse input via Bluetooth exhibits pointer lag and jitter
• Occurs in all apps: Notes, Safari, Mail, text fields, password entries, etc.
• Identical results using Apple USB-C cables
Reproducibility:
100%. Clean boots, minimal background activity, and isolated environments (including Airplane Mode) do not resolve the issue. Identical behavior across both iPhone and iPad.
Expected Behavior:
All HID-compliant external input devices — particularly Apple-branded ones — should provide low-latency, reliable, and consistent input over both USB-C and Bluetooth, especially in a production iOS/iPadOS release.
Actual Behavior:
External keyboards and mice exhibit:
• Lag
• Dropped characters
• Failed modifiers
• Degraded mouse tracking
Even with the latest hardware and clean configurations.
Severity:
Critical.
This is a platform-level failure affecting I/O at the user interaction layer. Input reliability is non-negotiable — especially on $2000+ flagship devices using Apple’s own peripherals.
Closing Note (for Apple engineering & peer devs):
This is not a beta regression — it’s a public release flaw that undermines iOS and iPadOS usability for power users, professionals, and accessibility communities alike. That Apple Magic Keyboard, Redragon, and Razer gear all fail equally and consistently should be a wake-up call.
Apple: this needs to be escalated. Now.
External input — one of the most basic subsystems in any OS — is broken on your highest-end devices.

If I want to display my corporations digital position would it be considered legal to use an iPhone SIM card reader as it seems to have a “data” point that hints at the idea of stabilization of intelligence that be found both off line and online.
I did a little research and it said Apples proprietary patents are referring to the size, ejection, magnetic trigger etc which leads me to want to know if the idea of using a SIM card reader to position the corporation as it uses a $USD specimen data file to position the idea of the corporation into a tangible format.
The part I’m referring to is the iPhone 11 sim tray and reader. The picture refers to the idea of the point on the back being similar to the ***** eye as something similar to the dollar seal.
I want to be a winner in the industry, I’ve got 50 plus “winner web domains” to bring to life and it’s time to buckle down and evolve the digital economy but first I want to validate the legality of me using disassembled Apple products to configure a “digital unit” that displays a “cyber analog”.
Beta two keeps hanging during the download process and says connect to wifi (which I am) or after hours it may download the beta 1.4gb file only to have to freeze in next processing step.
I have tried all the resets, reinstalling both the watch and the phone running OS26.1 Beta 2 etc.
The impact is the watch and the current software implementation is only getting a couple hours of battery usages before going dead
Hi I was thinking, wouldn’t it be awesome if Apple had a stock app? I know, it might sound crazy, but honestly, it would be a fantastic addition to their finance section! Imagine having a wallet, Apple credit card, and a stock app all in one place. In my opinion, that could totally revolutionize everything!

hi team
To continue testing Xcode 26 beta for our POS project's compatibility with the upcoming iOS 26 release in September, we’ve been running trials on various simulators. While the app works fine on iOS 18 simulators (iPad Pro/Air), it fails to launch on iOS 26-based iPad simulators with the following error:
"libswiftWebKit.dylib library is not loaded"...... SquareReaderSDK
Reason: tried: '/Users/username/Library/Developer/Xcode/DerivedData/ProjectnamePOS-buqsthxxbyqalydvfpxruhzgmymf/Build/Products/Debug-iphonesimulator/libswiftWebKit.dylib
(Detailed logs are shared below.)
Is there a known fix for this issue, or is a resolution expected in an upcoming beta release?

Hello Apple Arcade Team,
My partner and I are indie developers building premium spatial games for Apple platforms. We’ve created Cup Pong Galaxy, a 100% spatial game written specifically for Apple Vision Pro and we’d love to have it considered for Apple Arcade.
***** At-a-glance *****
Title: Cup Pong Galaxy
Platform: Designed from the ground up for Vision Pro (spatial gameplay)
Status: Approved for distribution on the App Store (release on hold pending Arcade interest)
TestFlight: https://testflight.apple.com/join/aCBcUUJb (fully functional build)
Game Footage:
https://www.youtube.com/watch?v=JGoJTfUwTdg
https://www.youtube.com/watch?v=CPExWW94ZvQ
https://www.youtube.com/watch?v=dJOKXVhRShA
***** Why it stands out for Apple Arcade *****
Original spatial mechanics: Natural throwing using custom hand gestures and a physics-accurate ping pong system built for Vision Pro.
Innovative collision system: Each animated alien has per-body-part collision objects that follow the armature's animation, allowing ping pong balls to bounce realistically off arms, legs, and heads.
Epic scale: 10 unique worlds with over 50 animated 3D alien characters, 150+ unique 3D obstacles, and 100 total levels.
Boss fights: Defeat bosses by hitting specific body parts with ping pong balls in full 3D space — we haven’t seen this implemented elsewhere on the App Store.
Cinematic world progression: Animated 3D level maps and victory scenes as players conquer worlds.
***** Business/fit *****
No ads or in-app purchases; prepared to align with Apple Arcade guidelines.
Actively adding Game Center integration.
We’ve started work on a second VisionOS game and would love to understand what makes a game a great fit for Arcade.
We’d be grateful if you could review Cup Pong Galaxy and let us know if there’s interest or point us to the correct person/process for Apple Arcade submissions. Any feedback is welcome — it will help us improve our next VisionOS game as well.
Thank you for your time and consideration.

Hey there,
I recently updated my iPhone to the iOS 26 developers beta version, and I’m encountering an issue on the Software Update page. It says “Unable to check for updates,” and I’m unable to revert to iOS 18.
Is this a temporary problem? Will I be able to update my iPhone in the future without needing to reset it?
Thanks

After updating to the newest beta on my iPhone 16 I'm stuck on this screen after accepting the terms:
No Internet Connection
Setup and activation of Apple Intelligence is unavailable when your device is offline. Connect to the internet and try again.
I tried several different networks and 5G but no luck..
I recently updated to tvOS 26 on my Apple TV 4K (1st generation) and was disappointed to find that apps I restrict no longer appear at all. In earlier versions, restricted apps would still be visible and simply prompt for a passcode — this was much more convenient for adults in the household.
Now, if I restrict apps for my children, they disappear completely. To use them again, I have to go deep into settings, turn restrictions off, and even recreate the passcode each time, which is frustrating and impractical for daily use.
I also tried adding a Kids user account, but most restrictions still apply system-wide. Only the Apple TV app behaves differently between users. This makes switching between parent and child accounts nearly pointless for managing access.
Please consider one or both of the following:
1. Bring back the passcode-on-launch behavior for restricted apps (instead of hiding them).
2. Give each user their own isolated settings environment, like how profiles work on iOS/iPadOS or even a fresh Apple TV—this way, restrictions, home screen, and app access could be personalized.
Families are a huge part of the Apple TV audience, and these recent changes have made it much harder to use the device in a shared household.
Thank you!
Hello, I'm experiencing issues with multiple apps on macOS related to network-related tasks. FIrst, I had problems with the network filter on Avast security. It told me to allow net work filtering, so I pressed the popup button that said allow filtering, but did nothing and gave me a error. Later on, on Nord VPN didnt work aswell, when I had to grant permission to configure a VPN. It didn't even give me a description of the error, just said something went wrong. I contacted NordVPN support, which didnt do anything exept for telling me to uninstall avast and restart my mac, which I did but was useless. Please help me.

Hello,
I recently submitted my Swift Student Challenge app playground and realized after submission that I accidentally selected Swift Playgrounds as the software to run it, instead of Xcode 26 or later.
My project builds and runs successfully in Xcode 26 using the iOS 26 SDK and simulator. However, when opening the same .swiftpm project in the Swift Playgrounds app on iPad, it does not compile because Swift Playgrounds currently only supports up to iOS 18 SDK and does not support iOS 26 APIs.
The submission itself is complete, builds correctly in Xcode, and was submitted before the deadline. The incorrect selection of Swift Playgrounds was an honest mistake during the submission process.
I wanted to ask whether reviewers are able to run the submission using Xcode 26 in cases like this, or if there is anything I should do.
Thank you very much for your time.

Hi all,
The SSDC states: Challenge submissions are due by Saturday, February 28, 2026, at 11:59 p.m. PST
I am curious does this apply to local timezone? I am GMT+0, so would this mean the deadline for GMT+0 is on the 1st of March at 7:59AM?
Kind regards,
Adam
I am trying to create a new app using IOS-26.1, macOS Tahoe 26.1 and Xcode 26.1 with Swift6. Is this a bug that is going to be addressed. This is in the Debug Console...Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)
(
"<NSAutoresizingMaskLayoutConstraint:0x10bb18870 h=--& v=--& _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x115da48c0.width == 0 (active)>",
"<NSLayoutConstraint:0x115ac2ee0 _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x115da48c0.leading == _UIButtonBarButton:0x115d40c80.leading (active)>",
"<NSLayoutConstraint:0x115ac30c0 H:[_UIButtonBarButton:0x115d40c80]-(0)-| (active, names: '|':_TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x115da48c0 )>",
"<NSLayoutConstraint:0x115ac2df0 'TB_Leading_Leading' H:|-(12)-[_UIModernBarButton:0x115d20a80] (active, names: '|':_UIButtonBarButton:0x115d40c80 )>",
"<NSLayoutConstraint:0x115ac2fd0 'TB_Trailing_Trailing' H:[_UIModernBarButton:0x115d20a80]-(12)-| (active, names: '|':_UIButtonBarButton:0x115d40c80 )>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x115ac2fd0 'TB_Trailing_Trailing' H:[_UIModernBarButton:0x115d20a80]-(12)-| (active, names: '|':_UIButtonBarButton:0x115d40c80 )>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
