ios swift parse: pickerview use array or dictionaries

Question

I am selecting some simple data from parse.com in order to fill a PickerView with it.

I have an "objectId" and a "name". This data I want to populate int my PickerView.

First I loaded the data into an array, which works fine... The PickerView is displaying the data the right way.

But as I want to save the selection from the pickerView to parse, I need the objectId of the selected language item - in this case the objectId.

When I use a dictionary:

var languagePickerValues = [String : String]()

// within the query loop
self.languagePickerValues[object.objectId] = name

I get errors here:

func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String! {
        return languagePickerValues[row]
    }
    func pickerView(pickerView: UIPickerView!, didSelectRow row: Int, inComponent component: Int){
        selectedLanguage.text = languagePickerValues[row]
        self.view.endEditing(true)
    }

as these functions try to access an array with an Int as numeric key which I don't have when working with dictionary.

For displaying purpose I could work with the array... To save the data to the API I need the objectId...

What would be the right thing to do?

Answer 1

what is object.objectId ? if its int or some other numeric type, then try:

self.languagePickerValues["\(object.objectId)"] = name

its because dictionary keys are strings, so just convert them with his:

"\(object.objectId)"
