Show contact.phoneNumber into cell

Question

Hello I'm currently working on a contacts application and I can't proper show the contact number into the cell, all I want is to display as a String without the Optional text and the (""). Here is my code:

let cell = tableView.dequeueReusableCell(withIdentifier: "contactCell", for: indexPath)
    let contact: CNContact!

    if inSearchMode {
        contact = filteredData[indexPath.row]
    } else {
        contact = contactList[indexPath.row]
    }

    cell.textLabel?.text = "\(contact.givenName) \(contact.familyName) \((contact.phoneNumbers.first?.value as? CNPhoneNumber)?.stringValue) "

    return cell
}

How Could I display the number under the name?

You should use `CNContactFormatter` to display the name from a contact. — rmaddy, Sep 09 '18 at 15:44

use this ?? nil-coalescing operator :

"\(contact.givenName ?? "") \(contact.familyName ?? "") \((contact.phoneNumbers.first?.value as? CNPhoneNumber)?.stringValue ?? "") "

Take this example:

let s: String? = "Hello"
let newString = s ?? "World" //s is not nil, so it is unwrapped and returned
type(of: newString)          //String.Type

If the operand on the left of ?? is nil then the one on its right is returned. the operand on the left of ?? is NOT nil, then it is unwrapped and returned.

let s2: String? = nil
let s3 = s ?? "World" //In this case s2 is nil, so "World" is returned
type(of: newString)   //String.Type

Use the same operator, I am updating the answer – ielyamani Sep 09 '18 at 13:54
Thanks for the example. Now how can I return it on the second line? – traiantomescu Sep 09 '18 at 14:02
You mean you want it as a description? – ielyamani Sep 09 '18 at 14:04
Why not use `cell.detailTextLabel.text = contact.phoneNumbers.first?.value as? CNPhoneNumber)?.stringValue ?? ""` – ielyamani Sep 09 '18 at 14:05
already tried that with: cell.detailTextLabel!.text = "\(contact.phoneNumbers.first?.value as? CNPhoneNumber)?.stringValue ?? "")" and get error – traiantomescu Sep 09 '18 at 14:09

You'll have to set the style of the cell to have detail labels, either in the storyboard, or [programatically](https://stackoverflow.com/a/27221118/2907715) – ielyamani Sep 09 '18 at 14:14
