There was a problem hiding this comment.
Looks like the comment should be updated after removing accessibility parameter.

Yeah, I've tested with an existing keychain store and seems working well with settings updated. We've updated keychain access in the past and haven't seen any regression issues. |

#4167 user reports getting IID becomes nil when a token exists. We suspect this is due to a security issue while keychain access level is set to kSecAttrAccessibleAlwaysThisDeviceOnly that is deprecated in iOS 13. Neitherless we should update it to kSecAttrAccessibleAfterFirstUnlockThisDeviceOnly since app only works in foreground so this is the proper access.
Also remove a parameter to set a optional access level for keychain cuz this parameter was never used.
