"Expected Declaration" with "{" - ios

Question

Such a beginner question but I am getting this error and I have tried to rearrange the braces in a million different ways but still return this error one way or another. I have managed to arrange the braces in a fashion to return only one error in one place. Here is a picture of the location of the error as well as the code.

// ViewController.swift
// TwoCVs

import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
}

I guess maybe you want your last method to be like this:
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
if collectionView == firstCV {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "firstCell", for: indexPath) as! FirstCollectionViewCell
cell.buttonOne.setTitle(firstData[indexPath.item], for: []) //allows for button title change in code above
cell.buttonOne.restorationIdentifier = "\(indexPath.row)"
return cell
} else if collectionView == secondCV {
// it's not the First Collection View, so it's the Second one
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "secondCell", for: indexPath) as! SecondCollectionViewCell
cell.buttonTwo.setTitle(secondData[indexPath.item], for: [])
cell.buttonTwo.restorationIdentifier = "\(indexPath.row + firstData.count)"
return cell
} else if collectionView == thirdCV {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "thirdCell", for: indexPath) as! ThirdCollectionViewCell
cell.buttonThree.setTitle(thirdData[indexPath.item], for: [])
cell.buttonThree.restorationIdentifier = "\(indexPath.row + secondData.count)"
return cell
}
}
