+### Swipe Actions
+
+Eureka 4.1.0 introduces the swipe feature.
+
+You are now able to define multiple `leadingSwipe` and `trailingSwipe` actions per row. As swipe actions depend on iOS system features, `leadingSwipe` is available on iOS 11.0+ only.
+
+Let's see how to define swipe actions.
+
+```swift
+let row = TextRow() {
+            let deleteAction = SwipeAction(
+                style: .destructive,
+                title: "Delete",
+                handler: { (action, row, completionHandler) in
+                    //add your code here.
+                    //make sure you call the completionHandler once done.
+                    completionHandler?(true)
+                })
+            deleteAction.image = UIImage(named: "icon-trash")
+
+            $0.trailingSwipe.actions = [deleteAction]
+            $0.trailingSwipe.performsFirstActionWithFullSwipe = true
+
+            //please be aware: `leadingSwipe` is only available on iOS 11+ only
+            let infoAction = SwipeAction(
+                style: .normal,
+                title: "Info",
+                handler: { (action, row, completionHandler) in
+                    //add your code here.
+                    //make sure you call the completionHandler once done.
+                    completionHandler?(true)
+                })
+            infoAction.backgroundColor = .blue
+            infoAction.image = UIImage(named: "icon-info")
+
+            $0.leadingSwipe.actions = [infoAction]
+            $0.leadingSwipe.performsFirstActionWithFullSwipe = true
+        }
+```

 ## Custom rows
 
 It is very common that you need a row that is different from those included in Eureka. If this is the case you will have to create your own row but this should not be difficult. You can read [this tutorial on how to create custom rows](https://blog.xmartlabs.com/2016/09/06/Eureka-custom-row-tutorial/) to get started. You might also want to have a look at [EurekaCommunity] which includes some extra rows ready to be added to Eureka.
