Hello, I'd like to consult everyone about abnormal frame rate issues encountered during Vision Pro usage, along with questions regarding refresh rates. I hope to gain insights or solutions:
My VP (M5) device experiences sudden frame rate drops during operation, with the following specific symptoms: During initial operation, the frame rate is approximately 90 frames per second, providing a smooth and normal user experience; However, it subsequently drops unexpectedly to 45 FPS, causing noticeable lag that severely impacts usability.
Actual usage logs provide a clear timeline: During the first session (23:47:35–23:57:41), the frame rate remained consistently stable at 90 FPS; After pausing usage for a period and restarting the device (00:22:30–00:30:47), the frame rate initially remained stable at 90 FPS. However, starting at 00:30:48, the frame rate suddenly dropped to 45 FPS and remained at this low rate until 00:36:18.
Additionally, we have two further questions:
What could cause this sudden, unexplained drop from 90 FPS to 45 FPS?
Our team has multiple VP M2 devices of the same model and noticed that some default refresh rates are 90Hz while others are 100Hz. What factors determine the frame rate of these devices? Why do refresh rate differences occur among identical models?
Have others encountered similar sudden frame rate drops? If so, could you share potential causes and troubleshooting approaches for resolving such issues? Thank you very much!

I made my payment via mobile payment on November 9th. Although my payment appears in the subscriptions section, it still hasn't been confirmed. I emailed support, but haven't heard back for 2 days.

Hi all,
I was hoping someone could help with this. I have an app that requires a subscription To access all content and features. However, some of our users’ subscriptions are not being detected and when they hit “Restore” they are faced with the error:
“Failed to restore with error code E_UNKNOWN and a TLS error caused the secure connection to fail“
We have asked the users to disable VPNs, change networks / data connection, restart devices etc. but this doesn’t seem to work. We are unable to produce this error on our test devices. Nor can we see any obvious issues in the code or on the servers.
Anyone any idea what could be causing this?

Hi,
If I set my Wallpaper to Black then go to any .jpg and select "Services-> Set Desktop Picture" the photo does not set. It may set a minute or so later. This action also prevents other colors from being set as if the system is busy with the photo somehow.
My desktop app that sets Wallpaper is also broken I believe because of the above.
Anyone have any workarounds or guidance?
I have filed a Feedback Assistant bug.
Thanks,
Jimmy

As l proceeded through the enrollment/membership.
I found the price is fixed for US$99. At the end. What about Renewal.
Is there any cost reduction for Apple Developers?
When trying to print an email with eM Client, the dialogue box pops up and the preview show the email's subject, To, and From lines in a long vertical column. This seems to only occur within the eM Client app and only on my Macbook Pro. I use the same email client on my Air with no issues. This is a recent development. I'm on Tahoe Beta 26.2.

Hi there,
I am new to Xcode26 and dragged my AppIcon.icon (created with Icon Composer) into the project. Then build failed with "Could not locate icontool".
Could anyone point me to the cleanest way to solve this? Any help would be appreciated, thanks!

Light shining effects can repeatedly be observed on older iPhone devices (12/13/14). This change is often seen after the device is rebooted or after a SystemMemoryReset.ips (System Analysis Data). It changes very often...
When you tap the list title in this yellow area in the Reminders app, the rows shift in an awkward/undesirable way. This may be a problem specific to older iPhone versions 12-15.

Since iOS 26.1 I'm running into the following iCloud issues.
Contacts are not being synced to iOS and iPad OS at all, no matter how I re-enable contact syncing I can't get them to sync.
Somehow, my Mac and iPad are able to send out iMessages, but not my iPhone. My iPhone can receive and sync what I've sent using my Mac and iPad
Unable to save an airdropped contact

Looking for more information on web push provisioning. I have a bank issuing credit card, which needs to be pushed to apple mobile wallet. Need to understand the APIs and other details required to do this.
Since updating to iOS 26, I can no longer link my iPhone WhatsApp app to WhatsApp Desktop on Windows. Every attempt to scan the QR code results in an “Unexpected error” message on the desktop app.
This issue only occurs on iOS. When using an Android device with the same version of WhatsApp Desktop and same network, linking works perfectly.
I contacted WhatsApp Support, and they confirmed that the problem appears to be related to iOS networking or connectivity handling rather than their app.

Hi All,
I am currently investigating an incident involving the iPhone 15 running iOS versions 18.6.2 and 26.0.1. The issue occurs when a user installs an application via the Company Portal. After installation, the app launches briefly and then crashes.
We have reviewed the Company Portal logs and checked Firebase Crashlytics, but neither provided any conclusive information regarding the root cause.
To further investigate, we asked 15 users to replicate the issue on similar devices, but the app worked correctly for all of them.
We have identified several potential causes that might be contributing to the issue:
Device configuration (model and OS version)
Device type (Corporate or BYOD)
Device policy settings
App installation process
Certificate or profile mismatch
SDK or library version compatibility/deprecation
SDK or framework initialization issues
API failure during app launch (exception handling)
Memory shortage
Could you please suggest any additional areas or approaches we should explore to help identify the root cause?
Thank you

The air conditioner is connected to the Home app via Matter Bridge, and two different methods have resulted in different behaviors:
After scanning the QR code to bind the air conditioner, a fan speed slider is displayed.
If the air conditioner is first added to MatterBridge (a gateway with Zigbee functionality), and then scanned to bind it to the Home app, the fan speed slider is not displayed.
Data reporting is the same.
fan-1.txt
fan-2.txt
nofan-1.txt
nofan-2.txt
nofan-3.txt
My app has three main SwiftData models: Collection, SavedItem, and Extract.
A Collection can contain subcollections (folders within folders) and SavedItems (files).
Each SavedItem can have child Extracts.
I'm preparing for the ability for users to be able to share Collections with each other.
Currently, my architecture treats each Collection as the root of its own CloudKit zone (a root parent Collection and all of its items and subcollections live in 1 zone).
This makes sharing and isolation straightforward, but it also means that moving a SavedItem or subcollection between Collections involves moving it across zones.
I’m trying to figure out the best pattern for handling these cross-zone moves while keeping data integrity, relationships, and sharing intact.
My understanding is that in CloudKit, and moving a record from Zone A to Zone B would require deleting it from Zone A and recreating it in Zone B - while somehow maintaining the link back to my local SwiftData store.
Has anyone run into this or know how best I should handle it?
3 days back,
when I unlocked my phone, I realised something off with icons and it’s display text.
i tried opening some apps but I see blank screen.
couldn’t restart the phone.
only option I was left with, is to drain the battery and turn on again.
i did and it was fine after restart.
Took some to drain battery.
luckily, I’m sitting in my home. What if I’m in emergency situation.

I'm asking if this directory list is a problem:
As root I see _unknown as the owner of a script I'm working on in Visual Studio. This ownership is unexpected. Does it indicate a filesystem issue or my inexperiene with MacOS?
