Refresh Control on Collection View

You can use the new refreshControl property on the UICollectionView to assign your UIRefreshControl.

 

override func viewDidLoad() {
    super.viewDidLoad()
        
    collectionView.delegate = self
    collectionView.dataSource = self
        
    refreshControl.addTarget(self, action: #selector(CollectionVC.refreshData), 
        for: UIControlEvents.valueChanged)
    refreshControl.attributedTitle = NSAttributedString(string: "Refresh Collection View",
        attributes: nil)
        
    if #available(iOS 10.0, *) {
        collectionView.refreshControl = refreshControl
    } else {
        collectionView.addSubview(refreshControl)
    }
}
    
func refreshData() {
    // Your get data code
        
    collectionView.reloadData()
    refreshControl.endRefreshing()
}
