How to show Strings from array in UITableView?

Question

I have an array like this:

var converter1 = [
        ["title": "value1", "kf": "1"],
        ["title": "value2", "kf": "4.324"]]

And if, else case in cellForRowAt:

let cell1 = tableView.dequeueReusableCell(withIdentifier: "resultCell") as! resultTableViewCell


            cell1.nameResult.text = converter1[indexPath.row]
            cell1.labelResult.text = converter1[indexPath.row]


            return cell1

How could I in nameResult.text show "title" and "kf" in labelResult?

Do you want to display the keys ("title" and "kf") or the values ("value1" and "1")? — vadian

@vadian “title” and “kf” - type names. I want to show it’s values like “value1” is “1” — Ivan Kisin

You have an array of dictionaries. Each dictionary seems to contain a "title" key/value pair and a "kf" key/value pair. I'm not completely clear on what you want to do, but you might try something like this:

let cell1 = tableView.dequeueReusableCell(withIdentifier: "resultCell") as! resultTableViewCell

cell1.nameResult.text = converter1[indexPath.row]["title"]
cell1.labelResult.text = converter1[indexPath.row]["kf"]

return cell1

Take a look at vadian's suggestion of creating a struct to model your data. That's a better way to go than using a dictionary.

Just get the values with key subscription

let item = converter1[indexPath.row]
cell1.nameResult.text = item["title"]
cell1.labelResult.text = item["kf"]

A much better solution is a custom struct

struct Converter {
   let title, kf : String 
}

let converter1 = [
    Converter(title: "value1", kf: "1"),
    Converter(title: "value2", kf: "4.324")]

...

let item = converter1[indexPath.row]
cell1.nameResult.text = item.title
cell1.labelResult.text = item.kf

Beat you to it, by at least 10 seconds! 😝

I like your edit to suggest a custom struct. (voted.) That's much safer and clearer than a generic dictionary. And if the source data is JSON, it's trivial to use the new JSONDecoder to create a custom struct directly from the JSON.

I good way to deal with this kind of problem is to use a playground and let type inference tell you what data types you're dealing with. Here's an example of taking your structure apart.

let converter1 = [
    ["title": "value1", "kf": "1"],
    ["title": "value2", "kf": "4.324"]]
let val0 = converter1[0]
if let strTitle = val0["title"],
    let strKf = val0["kf"] {
    print("\(strTitle) : \(strKf)")
}
