redundant_optional_initialization rule does not provide violations for ones inside the functions.

[VivoEx]

We do not see violations with redundant_optional_initialization rule for the vars inside the fuctions neither does it get autocorrected whereas works ok over the class variables.

class ClassName {
   ....
    var optionalVar: String? // This line provides violation and thus corrected during autocorrect
   
    func funcName() {
        var optionalVar: String? // This doesn't provide violation
        ....
    }

}

The problem here is that SourceKit doesn't return key.setter_accessibility for local variables. We use that to know if it's a var or a let, because if it's a let, we shouldn't warn.
