Title: Intermittent Keychain Data Loss on App Relaunch in iOS Beta 2

Hi everyone, I'm experiencing an intermittent issue with Keychain data loss on the latest iOS Beta 2. In about 7% of cases, users report that previously saved Keychain items are missing when the app is relaunched — either after a cold start or simply after being killed and reopened. Here are the key observations: The issue occurs sporadically, mostly once per affected user, but in 3 cases it has happened 4 times. No explicit deletion is triggered from the app. No system logs or error messages from Apple indicate any Keychain-related actions. The app attempts to access Keychain items, but they are no longer available. This behavior is inconsistent with previous iOS versions and is not reproducible in development environments. This raises concerns about: Whether this is a bug in the beta or an intentional change in Keychain behavior. Whether this could affect production apps when the final iOS version is released. The lack of any warning or documentation from Apple regarding this behavior. Has anyone else encountered similar issues? Any insights, workarounds, or official clarification would be greatly appreciated. Thanks!

Which “iOS Beta 2”?

We’re currently iOS 26 beta 8; if you’re testing on beta 2 it’s long past time to upgrade.

We can see from our logs that our Mobile App users use iOS 26 Beta version but we do not know exactly which beta version they use.

Our question is.

Whether this is a bug in the beta or an intentional change in Keychain behavior. Whether this could affect production apps when the final iOS 26 version is released. The lack of any warning or documentation from Apple regarding this behavior. Has anyone else encountered similar issues? Any insights, workarounds, or official clarification would be greatly appreciated. Thanks!
