@Developer Tools Engineer Thank you for providing useful suggestions! I found that the occurrence of NOT_FOUND errors in October is 10 times that of the past. And the logs collected on user devices also show a relation to CKError.Code.unknownItem. I also observed that CKFetchSubscriptionsOperation would return an internal CKPrettyError (not a CKError), which should also be a problem. I will submit a FB after further research.

Thanks! Saved me a day :)

🥹Thank heavens! I've been putting up with this bug for at least two years. It's confirmed that the issue no longer exists in Xcode 15.1 + iOS 17.2 simulator.

Good idea! Thanks for the reply.

I can still reproduce the issue on my MacBook Pro 15 inch (M3 Max), with latest Xcode 16 beta 6 and iOS 18.0 beta 7 (22A5342a), and the macOS version is 14.5 (23F79). The iOS 17 simulators are all fine. Physical devices are also no problem. 🤔

🤔 This looks good but does not work in my app. The app can be opened but the deep link is not send to the app.

Thanks for the reply! I suppose this bug is on iOS 17, right? Just want to make sure the result builder won’t crash again on iOS 18 when iOS 19 is released next year. 😅

Thanks for the reply! Just filed a FB: FB15038185

Update: Sorry for the misleading. This is a hack, not a solution. It's not recommended. Use it at your own risk.

Thanks for the fast reply!!

🤔 Hmm... I see. From my understanding, Foundation fixed JSONEncoder.sortedKeys in macOS Sequoia, but not the old JSONSerialization. If I use JSONSerialization, I can get stable serialization outputs just like Xcode 15 and 16. But if I use JSONEncoder, the output will be different.

Thanks! I'll try to simctl diagnose next time.

( ´Д`).... This is ugly. Definitely worth another feedback.

Submitting a new FB might help (｡ ́︿ ̀｡)

Thanks for the information. I can confirm that the issue has been fixed in iOS 18.1 beta 5.
