How can I group TableView items from a dictionary in swift?

Question

Lets consider this example:

import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { 
    @IBOutlet weak var tableV

Similar to https://stackoverflow.com/a/31136537/11098567 answer I would use classes instead of structs, so that you can manipulate or add to your values after it has been placed into the array.

@objc func addToInitialClassInstance() {

   let classInstance = Class(property1: String, property2: [CLass2.init(property1: String, property2: String)])
    let isAvailable = initialClassInstance.contains { (classInArray) -> Bool in
        if classInArray.property == classInstance.property {
            classInArray.property2.append(classInstance.property2[0])
            return true
        }
        return false
    }
    if !isAvailable {
        initialClassInstance.append(classInstance)
    }
    tableView.reloadData()
}
