Improvement of PasscodeLockController - There was no option for users using iOS 9 and above to have a 6 characters passcode. That's a must-have feature if it is available to use.

Previously, there was no option for users using iOS 9 and above to have a 6-character passcode. This enhancement introduces the ability for users on iOS 9 and above to set a 6-character passcode, providing an additional layer of security. Users on iOS versions below 9 can still set a 4-character passcode as intended.
