class HomeVC: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource,UICollectionViewDelegateFlowLayout{

@IBOutlet var collectionView: UICollectionView!

 override func viewDidLoad() {

super.viewDidLoad()
let nib = UINib(nibName: "MainCollectionViewCell", bundle: nil)
collectionView.registerNib(nib, forCellWithReuseIdentifier: "MainCollectionViewCell")

 }

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

let cell = collectionView.dequeueReusableCellWithReuseIdentifier("MainCollectionViewCell", forIndexPath: indexPath) as! MainCollectionViewCell
 cell.btnDetails.tag = indexPath.row// it will identify the tapped button cell index
cell.btnDetails.addTarget(self, action: #selector(connected(sender:)), for: .touchUpInside)
 cell.arrivingLabel.text = indexData.arriv
 cell.lblDiscountedPrice.text = indexData.discPrice

 
return cell
}

@objc func connected(sender: UIButton){
    let tag = sender.tag
    print(tag)

  }
