Swift 3 pass values to Controller on UICollectionViewCell button click

I am beginner in iOS development and I have implemented following screen using UICollectionView :

enter image description here

CollectionViewCell File Code is:

import UIKit

class EventCell: UICollectionViewCell{

var classEvent: Event?

@IBOutlet weak var eventTitle: UILabel!
@IBOutlet weak var eventTeams: UILabel!
@IBOutlet weak var eventTime: UILabel!
@IBOutlet weak var eventTeamOneImage: UIImageView!
@IBOutlet weak var eventTeamTwoImage: UIImageView!

@IBOutlet weak var leaderboardButton: UIButton!

var datasourceItem: Any?{
    didSet{
        guard let event = datasourceItem as? Event else { return }
        classEvent = event

        eventTitle.text = "Match \(event.matchNo) (\(event.matchStage))"
        eventTeams.text = "\(event.teamOne.nameAttr) vs \(event.teamTwo.nameAttr)"
        eventTime.text = "\(event.getEventLockTimeAsString())"
        eventTeamOneImage.loadImageUsingCache(withUrl: event.teamOne.flagPhoto)
        eventTeamTwoImage.loadImageUsingCache(withUrl: event.teamTwo.flagPhoto)
        leaderboardButton.addTarget(self, action: #selector(handleLeaderBoardClick), for: .touchUpInside)
    }
}

@IBAction func leagueButton(_ sender: Any) {
}

weak var delegate: HomeControllerDelegate?
func handleLeaderBoardClick() {
    if let matchId = classEvent?.id {
        print(matchId)
        delegate?.clickOnLeaderBoard(matchId: matchId)
    }
}   
 }

Now on click on Leaderboard button(icon with 1,2,3) I would like to open new LeaderBoard Controller and pass matchId which is classEvent.id

How can I pass values to the new controller? And what is the best way to do that.

Three easy steps to get what u want:

  1. Make a BaseViewController class a subclass of UiViewController. This class would be the alternate of UiViewcontroller in your project,it means while creating any viewcontroller BaseViewController will be the parent class.

  2. Declare a variable in BaseViewController.e.g- var data: Any?

  3. Then while moving from a viewcontroller to another , simply assign any type of data to that variable declared in BaseViewController. And in any lifecycle method of your new viewcontroller you will get that data using self.data.

You can pass the match Id via segue:

In LeaderBoard Controller set a property:

var matchId:Int?

Set a segue between the controller and add an identifier: On Click leaderboard button:

self.performSegueWithIdentifier("yourSegueIdentifier", sender: self)

Add the segue method:

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) {

    if segue,identifier == "yourSegueIdentifier" {
        let destinationVC = segue.destinationViewController as LeaderbardController
        destinationVC.matchId = classEvent.id
        }
}
    }
