Hello,
Turning on iCloud Drive sync does not work in iOS 27 simulators. When I sign into an iCloud account and try to enable it by tapping the switch in the iCloud Drive settings within the iCloud account area of Settings, the switch doesn't stay on and the feature is never enabled.
I don't get an error or anything telling me what's going on. Anyone else seeing this?
When I create a new simulator for iPhone 26.5 it seems to work fine just as before.
I've tested this with Xcode 26.6 17F113 and Xcode 27 RC 27A266a.
