If you want to use only text while making swipe actions then you can use iOS default swipe actions but if you want image and text  then you have to customize it  I have found a great tutorial and sample that can resolve this problem   Try out this repository to get the custom swipe cell  You can add multiple option here   http   iosbucket blogspot in 2016 04 custom-swipe-table-view-cell 16 html  https   github com pradeep7may PKSwipeTableViewCell

As I think  It s not best way to using UIGestureRecognizer-based cells    First  you ll not have any options to use CoreGraphics    Perfect solution  will UIResponder or one UIGestureRecognizer for whole table view  Not for every UITableViewCell  It will make you app stuck

You can use UITableViewRowAction s backgroundColor to set custom image or view  The trick is using UIColor patternImage     Basically the width of UITableViewRowAction area is decided by its title  so you can find a exact length of title or whitespace  and set the exact size of image with patternImage   To implement this  I made a UIView s extension method   func image   - gt  UIImage       UIGraphicsBeginImageContextWithOptions bounds size  isOpaque  0      guard let context   UIGraphicsGetCurrentContext   else           return UIImage             layer render in  context      let image   UIGraphicsGetImageFromCurrentImageContext       UIGraphicsEndImageContext       return image      and to make a string with whitespace and exact length   fileprivate func whitespaceString font  UIFont   UIFont systemFont ofSize  15   width  CGFloat  - gt  String       let kPadding  CGFloat   20     let mutable   NSMutableString string          let attribute    NSFontAttributeName  font      while mutable size attributes  attribute  width  lt  width -  2   kPadding            mutable append                return mutable as String     and now  you can create UITableViewRowAction   func tableView   tableView  UITableView  editActionsForRowAt indexPath  IndexPath  - gt   UITableViewRowAction         let whitespace   whitespaceString width  kCellActionWidth      let deleteAction   UITableViewRowAction style    default   title  whitespace     action  indexPath  in            do whatever you want               create a color from patter image and set the color as a background color of action     let kActionImageSize  CGFloat   34     let view   UIView frame  CGRect x  0  y  0  width  kCellActionWidth  height  kCellHeight       view backgroundColor   UIColor white     let imageView   UIImageView frame  CGRect x   kCellActionWidth - kActionImageSize    2                                                y   kCellHeight - kActionImageSize    2                                                width  34                                                height  34       imageView image   UIImage named   x       view addSubview imageView      let image   view image        deleteAction backgroundColor   UIColor patternImage  image       return  deleteAction      The result will look like this     Another way to do this is to import custom font which has the image you want to use as a font and use UIButton appearance  However this will affect other buttons unless you manually set other button s font   From iOS 11  it will show this message  TableView  Setting a pattern color as backgroundColor of UITableViewRowAction is no longer supported   Currently it is still working  but it wouldn t work in the future update                                               For iOS 11   you can use   func tableView   tableView  UITableView  trailingSwipeActionsConfigurationForRowAt indexPath  IndexPath  - gt  UISwipeActionsConfiguration      let deleteAction   UIContextualAction style   normal  title   Delete      action  view  completion  in        Perform your action here       completion true         let muteAction   UIContextualAction style   normal  title   Mute      action  view  completion  in        Perform your action here     completion true         deleteAction image   UIImage named   icon png     deleteAction backgroundColor   UIColor red   return UISwipeActionsConfiguration actions   deleteAction  muteAction

create a view on the custom cell in the table view and apply PanGestureRecognizer to the view on the cell Add the buttons to the custom cell  when you swipe the view on the custom cell then the buttons on the custom cell will be visible    UIGestureRecognizer  recognizer     UIPanGestureRecognizer alloc  initWithTarget self action  selector handlePan         recognizer delegate   self       YourView addGestureRecognizer recognizer     And handle the panning on the view in the method   if  recognizer state    UIGestureRecognizerStateBegan           if the gesture has just started  record the current centre location      originalCenter   vwCell center        2 if  recognizer state    UIGestureRecognizerStateChanged           translate the center     CGPoint translation    recognizer translationInView self       vwCell center   CGPointMake  originalCenter x   translation x   originalCenter y          determine whether the item has been dragged far enough to initiate    complete      OnDragRelease   vwCell frame origin x  lt  -vwCell frame size width   2         3 if  recognizer state    UIGestureRecognizerStateEnded           the frame this cell would have had before being dragged     CGPoint translation    recognizer translationInView self        if   originalCenter x translation x lt 22              vwCell center   CGPointMake 22   originalCenter y           IsvwRelease YES             CGRect originalFrame   CGRectMake 0  vwCell frame origin y                                        vwCell bounds size width  vwCell bounds size height       if    deleteOnDragRelease               if the item is not being dragged far enough   snap back to the original location          UIView animateWithDuration 0 2                          animations                                 vwCell frame   originalFrame
