How To Get The Data Out, Inside if/else Statement in Swift

I have two pickerViews in ViewController and a Struct where I made a function which will get data of PickerViews. In didSelectRow func of PickerView I wrote the below code.

func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        if pickerView == fromPickerViewRolled {
            let optionArray1 = currencyManager.currencyArrayOption1[row]
        }
        else if pickerView == toPickerViewRolled {
    
            let optionArray2 = currencyManager.currencyArrayOption2[row]   
        }
    }

How may I get the data of optionArray1 and ..Array2 outside of if/else so that I can use in function. Any help would be appreciated. Looking forward for an answer.
