Yes, it is possible for a state variable to not be updated within a switch statement in Swift/SwiftUI. This can happen if the switch statement does not include a case that matches the current value of the state variable, in which case the state variable will not be updated. It is important to make sure that all possible values of the state variable are covered in the switch statement in order to ensure that it is always updated correctly.
