How to implement “share button” in Swift

Swift 5:

    // Setting description
    let firstActivityItem = "Description you want.."

    // Setting url
    let secondActivityItem : NSURL = NSURL(string: "http://your-url.com/")!
    
    // If you want to use an image
    let image : UIImage = UIImage(named: "your-image-name")!
    let activityViewController : UIActivityViewController = UIActivityViewController(
        activityItems: [firstActivityItem, secondActivityItem, image], applicationActivities: nil)
    
    // This lines is for the popover you need to show in iPad
    activityViewController.popoverPresentationController?.sourceView = (sender as! UIButton)
    
    // This line remove the arrow of the popover to show in iPad
    activityViewController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.down
    activityViewController.popoverPresentationController?.sourceRect = CGRect(x: 150, y: 150, width: 0, height: 0)
    
    // Pre-configuring activity items
    activityViewController.activityItemsConfiguration = [
    UIActivity.ActivityType.message
    ] as? UIActivityItemsConfigurationReading
    
    // Anything you want to exclude
    activityViewController.excludedActivityTypes = [
        UIActivity.ActivityType.postToWeibo,
        UIActivity.ActivityType.print,
        UIActivity.ActivityType.assignToContact,
        UIActivity.ActivityType.saveToCameraRoll,
        UIActivity.ActivityType.addToReadingList,
        UIActivity.ActivityType.postToFlickr,
        UIActivity.ActivityType.postToVimeo,
        UIActivity.ActivityType.postToTencentWeibo,
        UIActivity.ActivityType.postToFacebook
    ]
    
    activityViewController.isModalInPresentation = true
    self.present(activityViewController, animated: true, completion: nil)
