It is not redirecting to the VC I want it to. It is not even registering the click. I tested this with a print statement. Here is the code. The function giving me the problem is the last one of the code

homeVC.swift code

It is a bit hard to read in the small editor window.

Where should the click be registered ?

Note: your classes names should begin with Uppercase.

The click should be registered when the user clicks the picture. This is the function

Code Block override func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
				
				print("clicked	did select")
				// send post uuid to "postuuid" variable
				postuuid.append(uuidArray[indexPath.row])
				
				// navigate to post view controller
				let post = self.storyboard?.instantiateViewController(withIdentifier: "postVC") as! postVC
				self.navigationController?.pushViewController(post, animated: true)
		}

I have a problem finding my way in the code.

In viewDidLoad, you add a subView. Seems it covers completely the collectionView (addSubView adds to the top) ?
When you tap on the image, the tap is intercepted.

Try to addSubView behind collectionView with insertSubview(_:belowSubview:)

Should I add that instead of

Code Block collectionView?.addSubview(refresher)

That did not work. Could it be because the tap gets intercepted by some of the gesture recognizers. I have 3 in local scope inside the class but not inside a function.

Code Block let postsTap = UITapGestureRecognizer(target: self, action: #selector(homeVC.postsTap))
						postsTap.numberOfTapsRequired = 1
						header.posts.isUserInteractionEnabled = true
						header.posts.addGestureRecognizer(postsTap)
		
						let followersTap = UITapGestureRecognizer(target: self, action: #selector(homeVC.followersTap))
						followersTap.numberOfTapsRequired = 1
						header.followers.isUserInteractionEnabled = true
						header.followers.addGestureRecognizer(followersTap)
				
						
						let followingsTap = UITapGestureRecognizer(target: self, action: #selector(homeVC.followingsTap))
						followingsTap.numberOfTapsRequired = 1
						header.followings.isUserInteractionEnabled = true
						header.followings.addGestureRecognizer(followingsTap)
				
						return header
