Im trying to load a tableview xib containing a collectionView. collectionView contains a list of files as to be downloaded and opened.

class CommentsCell: UITableViewCell, UICollectionViewDelegate, UICollectionViewDataSource, UIDocumentInteractionControllerDelegate {

var dic = UIDocumentInteractionController()
var imgCollection: [TicketAttachment] = [TicketAttachment]()
@IBOutlet weak var collectionView: UICollectionView!
@IBOutlet weak var imgProfilePic: UIImageView!
@IBOutlet weak var lblName: UILabel!
@IBOutlet weak var lblDate: UILabel!
@IBOutlet weak var txvComments: UITextView!
override func awakeFromNib() 
 super.awakeFromNib()
 dic.delegate = self
 self.collectionView.dataSource = self
 self.collectionView.delegate = self
 self.collectionView.register(UINib.init(nibName: "AttachmentViewCell", bundle: nil), forCellWithReuseIdentifier: "AttachmentViewCell")



func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) 
 let fileUrl = imgCollection[indexPath.row].fileUrl?.absoluteString
 let url = URL(string: Api.domain + fileUrl!)

 let destination = DownloadRequest.suggestedDownloadDestination(for: .documentDirectory)

 sharedAFManager.AFManager.download(url!, to: destination)
 .downloadProgress(closure: _ in
 SVProgressHUD.show()
 ).response(completionHandler: (downloadResponse) in
 SVProgressHUD.dismiss()
 self.dic.url = downloadResponse.destinationURL
 self.dic.uti = downloadResponse.destinationURL!.uti
 let rect = CGRect(x: 0, y: 0, width: 100, height: 100)
 self.dic.presentOpenInMenu(from: rect, in: self.view, animated: true)
 )

self.dic.presentOpenInMenu(from: rect, in: self.view, animated: true)
Value of type 'CommentsCell' has no member 'view'

Tableview XIB design:

Pass viewController object to UITableViewCell and replace line with

self.dic.presentOpenInMenu(from: rect, in: vc.view, animated: true)

In ViewController:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell 

 .....
 cell.vc = self

In CommentsCell:

class CommentsCell: UITableViewCell, UICollectionViewDelegate, UICollectionViewDataSource, UIDocumentInteractionControllerDelegate 

 weak var vc: UIViewController!

 ........

 func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) 
 let fileUrl = imgCollection[indexPath.row].fileUrl?.absoluteString
 let url = URL(string: Api.domain + fileUrl!)

 let destination = DownloadRequest.suggestedDownloadDestination(for: .documentDirectory)

 sharedAFManager.AFManager.download(url!, to: destination)
 .downloadProgress(closure: _ in
 SVProgressHUD.show()
 ).response(completionHandler: (downloadResponse) in
 SVProgressHUD.dismiss()
 self.dic.url = downloadResponse.destinationURL
 self.dic.uti = downloadResponse.destinationURL!.uti
 let rect = CGRect(x: 0, y: 0, width: 100, height: 100)
 self.dic.presentOpenInMenu(from: rect, in: vc.view, animated: true)
 )
 

You can not presentOpenInMenu from UIView. You need to use UIviewContoller's instance to Present ViewController so You can simply Pass View Controller object in tableview cell or use below Extension of uiview

extension UIView 

 var parentViewController: UIViewController? 
 var parentResponder: UIResponder? = self
 while parentResponder != nil 
 parentResponder = parentResponder!.next
 if let viewController = parentResponder as? UIViewController 
 return viewController
 
 
 return nil
 

and presentOpenInMenu like

self.parentViewController?.presentOpenInMenu(from: rect, in: self.view, animated: true)
