Already raised this issue with v11.1.0 & it's happening in v12.0.1 as well. Previously raised issue url is given below.

Additionally, we noted a method [[SFScreenLockManagerInternal shared] checkForScreenLockUsers] called after [SFSDKSalesforceSDKUpgradeManager upgrade]. Whether the iPad lock screen shows because of this implementation?

@VenkataramanK does your app store anything in the keychain outside of what Mobile SDK automatically does? And if so what access control is set for them? Also, do you happen to have any device/console logs aside from the crash log?

@bbirman : Thanks for your attention!!!

We don't have any requirement to store in keychain from application aspect. Only SDK based keychain is live. Also, it's only happening in Production environment for significant number of people. we can't reproduce this crash in our lower environments.

Note:

1. Previously our app used Salesforce Hybrid SDK V9.1, later we moved to V11.1 & V12.0.1. We suspect any Keychain values mismatch may cause this issue.
2. Our application is Enterprise app can be downloaded from our internal Appstore.
