Xcode 26 build fails with “Could not locate icontool” when using .icon file — how to fix?
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!

macOS sequoia docking station sporadically disconnects
After recently updating my MacBook Pro (14-inch, 2021, M1 Pro) to macOS Sequoia (15.6), my docking station sporadically disconnects and reconnects about once every 1-5 minutes. This causes my external screens to switch off for about a second, and my external drive to disconnect. This has (obviously) completely broken my workflow, and I've had to resort to connecting two screens directly to the MacBook. I've had to completely disconnect the external drive for fear of corrupting due to the sudden disconnects. I've seen other people report the same or similar issues here, and other places. I've tried all kinds of fixes suggested on various forums (reinstalled drivers, cleared preference files, etc.) without any luck. To be frank, this is a completely unacceptable bug that needs to be fixed ASAP. I cannot accept that installing an os update completely breaks something as fundamental as connecting to external devices via a docker. Especially when this worked completely fine on macOS 13, and I was essentially forced to update because the (working) macOS 13 was no longer supported.

iOS 26 - S/MIME Encryption / Certificates
Hi everyone. Since the update to iOS 26, we are no longer able to tap the person's name and view the certificate of a signed email and choose to install the certificate or remove it. This has always worked just fine but seems to be broken on iOS 26 and I have verified that it does not work on iOS 26.1 beta as well. The part that is strange is it does work just fine on an iPad running iPad OS 26. This makes it impossible to send encrypted emails to someone via the mail app on an iPhone. I have found a temporary workaround which is to install Outlook for iOS and install the certificates through that app which then allows me to send encrypted emails via Outlook. This appears to be a bug just with the iPhone as I have also seen a few other people online talking about the same problem. Has anyone found a solution to this?

CloudKit - moving record objects between zones
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?

iPhone/iPad iCloud is a piece of junk right now.
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

App stops responding to touch; works normally otherwise
Some users of my app complain that it stops responding to touch after a while. The screen is still updating, and the app seems to be working normally otherwise. It just doesn't respond to any touches anymore. It is not a problem with the touchscreen itself, because the user is able to swipe up to get to the home screen, and then interact with other apps as normal. When re-opening my app, it is still unresponsive to touch. The only way to solve it, is to restart the app. Does anybody have a similar experience, and knows what could cause it? The app is based on UIKit, and still written in Objective-C, if it matters. The iOS version involved does not seem to matter, it happened with a couple of them.

diskutil "eraseDisk" on disk0 using terminal
Hi Apple Team & Everyone, Can someone guide me why sending 'diskutil eraseDisk APFS "WIPED" GPT /dev/disk0' command via terminal to remove/wipe the main physical drive (disk0) is failed? I tried booting into recovery mode, but it still didn’t work. The command returned the following error: Started erase on disk0 Unmounting disk The volume on disk0 couldn't be unmounted because it is in use by process 0 (kernel). Error: -69877: Couldn't open device I understand that we can use Disk Utility (GUI) to unmount and erase the drive. Is it possible to perform this operation via Terminal to erase disk0? I would appreciate any guidance on this. Regards, Winson

Incorrect keyboard frame on iOS 26 when using Secure Text with Autofill
Area: Software Update Type of Feedback: Application Bug Description Device: iPhone 13 Pro running iOS 26 Build environment: Xcode 16.4 Problem description: When a text field has secureTextEntry = YES and Password Autofill / Passkeys is active, the autofill panel is not included in the rect reported from the keyboard notifications (UIKeyboardFrameEndUserInfoKey or others). As a result, when calculating the offset to move the screen up and reveal the hidden input field, the field is not displayed correctly because the reported keyboard height is smaller than the actual visible height. Observed behavior: This only occurs on devices running iOS 26 built with Xcode 16.4. On previous versions of iOS, with the same settings (secureTextEntry and Autofill active), the rect correctly includes the autofill panel height, and the UI works as expected. I tested with both UIKeyboardDidShowNotification and UIKeyboardWillChangeFrameNotification, and in both cases the behavior is the same: the height is incorrect (smaller than expected with the autofill panel). What I expect / questions: That UIKeyboardFrameEndUserInfoKey (or the related notification) correctly reports the total area covered by the keyboard, including any password autofill panel, when secureTextEntry is active. That the new behavior in iOS 26 be documented if this omission is intentional, or otherwise considered a bug if it is not. If there is any official workaround suggested by Apple for developers affected by this issue while a fix is provided. Thank you for your support.

Urgent: Locked Account Holder – Need Help
Hello Apple Developer Community, I need some assistance with my account. I created a new developer account for a new project I am working on, and paid the apple developer fee. Everything was working fine for a few weeks, I was able to get my app on TestFlight and invite testers to it, as well as push updates and get feedback. The testers were family/business partners. As of a few days ago, I was locked out of my account. I first tried resetting my password, and was then met with an email claiming my account was locked with no additional information. I am trying to understand how I can either unlock my account, or transfer my existing app to a new account, so that I do not have to bother my users with downloading a new app. Additionally, I would like some help in understanding how I can safeguard myself from this issue in the future, especially given this would not be fun if my app were published. Could anyone please assist me, provide me with any advice, or point me to a place where I could get support? I spent 25 minutes on the phone with apple support, and was treated excellently as I've come to expect of Apple, but unfortunately was not given any help as the support did not have additional information. I'm hoping I'm asking in the right place, and can get some help! Thanks in advance, Fritz

System Data Occupying Half of My Storage
If Apple truly requires this much space for the system, I honestly don’t see the point of having a 256GB device. I have no way of knowing what exactly is included in “System Data,” and I cannot modify or manage it. This is extremely frustrating and confusing for users. Can someone explain why this is necessary?
