“Xcode”

Hi. I am facing this issue as well. Tried this out and I am getting this as a response: xcrun simctl spawn booted launchctl kickstart -k system/com.apple.pboard Could not find service com.apple.pboard in domain for system Upon further investigation, if you copy something within the simulator and try to paste it, it works within the context of the simulator. However, when u try to paste text you copied from the mac it doesn't get carried forward to the simulator and instead pastes what you copied earlier on the simulator. I have tried the 'Automatically Sync Pasteboard' option under Edit in simulator as well but to no avail. If i run the terminal commands as well to paste from the simulator's uuid like the following: xcrun simctl pbpaste 99D03E66-6DA6-40AC-8E9F-98874D8F6464 xcrun simctl pbcopy 99D03E66-6DA6-40AC-8E9F-98874D8F6464 simulator copy It would only paste what I wrote within the simulator. This happens on iOS 26.4 simulators after updating to xCode 26.4

Hi Michael, Thank you for looking into this. To clarify, this issue is not reproducible when running locally (Debug or Release). It only occurs in TestFlight distribution builds. In our production app as well as the minimal sample project, the behavior is consistent — the bug only appears when installed via TestFlight, not when run directly from Xcode. Regarding the video - at 0:31 you can see the cube briefly disappears after Lock In Place. That is the moment we are referring to. Could you please try the following: Archive the sample project Upload to TestFlight Install via TestFlight on the device Reproduce the Lock In Place steps I am confident it will be reproducible in that configuration. I am happy to provide another screen recording specifically showing this if that would help. Please let me know if you need anything else. Thanks, Kunal

Xcode 26.4 final is available and has resolved this issue. The iOS 26.4 simulator does correctly display emoji/unicode. Install Xcode 26.4 from the Mac App Store or similar to resolve this issue.

Thank you to Albert for his post above. With regard to the post, for me following the instructions to reinstall the iOS 26.3 and simulator did not work as it reinstalled the same simulator with the same issue. However I am pleased to report that I tested the Xcode 26.4 RC with the accompanying simulator and it does resolve this issue. I see that a final iOS 26.4 has been released, so the matching final Xcode is due very shortly to put this behind us. Cheers.

Thanks for filing the feedback report (FB22325366). Yeah, that does look like an issue on the framework side. I can reproduce the crash without the need of adding a second relationship with Xcode 26.4 (17E192) + iOS 26.4 (23E244) Simulator. Best, —— Ziqiao Chen  Worldwide Developer Relations.

Thanks for the post, in this page you'll find a sample for AppClips as well as the first note will provide you the 101 of App Clips. I always recommend developers to go over all those videos and documentation liked on that note. Then download the app, look at every single configuration from that app including the Clip target! https://developer.apple.com/documentation/appclip/fruta-building-a-feature-rich-app-with-swiftui In my opinion and without going deep in your solution, the reason your AASA endpoint is never getting called when you scan the QR code is due to a common misconception about how iOS handles App Clips and Universal Links, the iOS device does not fetch the AASA file at the moment you scan a QR code. Downloads the file at app installation time and there is also a delay. When you scan a QR code, iOS checks its local cache and Apple's CDN records to see if that URL is registered to an App Clip. If Apple's CDN hasn't validated your AASA file, or if the TestFlight configuration is incomplete, iOS fa

After additional testing, this appears to be an orphaned MobileAsset cleanup issue rather than a normal simulator uninstall problem. The runtime payload remains on disk under /System/Library/AssetsV2, but in some cases Xcode no longer exposes it in Components/Platforms and simctl does not have a usable reference to remove it cleanly. In other words, the asset still occupies space, but the supported management tools have effectively lost authoritative control over it. At that point the problem becomes structural: the remaining files are in a SIP-protected system location. So even if the exact asset folder can be identified, it cannot be manually removed through normal user-space means while SIP is enabled. That leaves no supported path to reclaim the space once the asset has fallen out of Xcode/simctl management. Technically, the remaining workaround is to disable SIP and remove the orphaned asset manually, but that is not a reasonable solution for routine simulator runtime cleanup. SIP exist

@shenbj Thanks for this great post! I think the Claude Agent for Xcode requires an active internet connection to communicate with Anthropic's servers and is not designed for native offline operations at this time. However I think you should file an enhancement request for this. If you'd like us to consider adding the necessary functionality, please file an enhancement request using Feedback Assistant. Once you file the request, please post the FB number here. If you're not familiar with how to file enhancement requests, take a look at Bug Reporting: How and Why?

@garysmckiernan You are the MAN. I have been stuck on iOS 18.2 sim for over 6 months. Tried everything including upgrading to Tahoe, and next step would have been reinstalling macOS. How did you know to delete the Xcode defaults preferences? How were you able to diagnose and come up with this fix? I couldn't figure out how to diagnose it or locations to reset to try and fix it.
