It’s now 2026 and I’m still having the same issue, binary data synced with CloudKit is roughly ~10x on iCloud when checking inside iOS iCloud storage viewer… Come on Apple get it together!

Same here with Xcode 16, have you found a solution? EDIT: Found a temporary solution, change the language dropdown to the language of your dataset

All right, I have finally fixed it: TURN OFF ADVANCED DATA PROTECTION IN ICLOUD SETTINGS

I have the same issue as well, any fix? I tried using my email and password to login instead of Passkey but it's still not working

I fixed it by flushing the DNS, try this: Open the Terminal app Enter sudo dscacheutil -flushcache, enter your password if prompted Enter sudo killall -HUP mDNSResponder Reconnect your WiFi / Ethernet Or you can simply flush the DNS with CleanMyMac, either method works just the same.

Same issue here with Xcode 15 (Running on M1 Max with Ventura 13.5.2)

2023 September, still cannot delete a keyword, come Apple...

But how can I update / publish app that is built with Xcode 14.3.1 on macOS Sonoma?

Fixed: Xcode accidentally downloaded multiple iOS 17 Simulators and got confused by itself...
