*Swipeable UITableViewCell/UICollectionViewCell based on the stock Mail.app, implemented in Swift.*






## About



A swipeable `UITableViewCell` or `UICollectionViewCell` with support for:



* Left and right swipe actions

* Action buttons with: *text only, text + image, image only*

* Haptic Feedback

* Customizable transitions: *Border, Drag, and Reveal*

* Customizable action button behavior during swipe

* Animated expansion when dragging past threshold

* Customizable expansion animations

* Support for both `UITableView` and `UICollectionView`

* Accessibility

* Dark Mode



## Background



Check out my [blog post](https://jerkoch.com/2017/02/07/swiper-no-swiping.html) on how *SwipeCellKit* came to be.



## Demo



### Transition Styles



The transition style describes how the action buttons are exposed during the swipe.



#### Border 






#### Drag 






#### Reveal 






#### Customized






### Expansion Styles



The expansion style describes the behavior when the cell is swiped past a defined threshold.



#### None






#### Selection






#### Destructive






#### Customized






## Requirements



* Swift 5.0

* Xcode 10.3+

* iOS 9.0+

## Usage for UITableView



Set the `delegate` property on `SwipeTableViewCell`:



````swift

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

    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as! SwipeTableViewCell

    cell.delegate = self

    return cell

}

````



Adopt the `SwipeTableViewCellDelegate` protocol:



````swift

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath, for orientation: SwipeActionsOrientation) -> [SwipeAction]? {

    guard orientation == .right else { return nil }



    let deleteAction = SwipeAction(style: .destructive, title: "Delete") { action, indexPath in

        // handle action by updating model with deletion

    }



    // customize the action appearance

    deleteAction.image = UIImage(named: "delete")



    return [deleteAction]

}

````



Optionally, you can implement the `editActionsOptionsForRowAt` method to customize the behavior of the swipe actions:



````swift    

func tableView(_ tableView: UITableView, editActionsOptionsForRowAt indexPath: IndexPath, for orientation: SwipeActionsOrientation) -> SwipeOptions {

    var options = SwipeOptions()

    options.expansionStyle = .destructive

    options.transitionStyle = .border

    return options

}

````

## Usage for UICollectionView



Set the `delegate` property on `SwipeCollectionViewCell`:



````swift

override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! SwipeCollectionViewCell

    cell.delegate = self

    return cell

}

````



Adopt the `SwipeCollectionViewCellDelegate` protocol:



````swift

func collectionView(_ collectionView: UICollectionView, editActionsForItemAt indexPath: IndexPath, for orientation: SwipeActionsOrientation) -> [SwipeAction]? {

    guard orientation == .right else { return nil }



    let deleteAction = SwipeAction(style: .destructive, title: "Delete") { action, indexPath in

        // handle action by updating model with deletion

    }



    // customize the action appearance

    deleteAction.image = UIImage(named: "delete")



    return [deleteAction]

}

````



Optionally, you can implement the `editActionsOptionsForItemAt` method to customize the behavior of the swipe actions:



````swift    

func collectionView(_ collectionView: UICollectionView, editActionsOptionsForItemAt indexPath: IndexPath, for orientation: SwipeActionsOrientation) -> SwipeOptions {

    var options = SwipeOptions()

    options.expansionStyle = .destructive

    options.transitionStyle = .border

    return options

}

````

### Transitions



Three built-in transition styles are provided by `SwipeTransitionStyle`:  



* .border: The visible action area is equally divide between all action buttons.

* .drag: The visible action area is dragged, pinned to the cell, with each action button fully sized as it is exposed.

* .reveal: The visible action area sits behind the cell, pinned to the edge of the table view, and is revealed as the cell is dragged aside.



See [Customizing Transitions](https://github.com/SwipeCellKit/SwipeCellKit/blob/develop/Guides/Advanced.md) for more details on customizing button appearance as the swipe is performed.



#### Transition Delegate



Transition for a `SwipeAction` can be observered by setting a `SwipeActionTransitioning` on the `transitionDelegate` property. This allows you to observe what percentage is visible and access to the underlying `UIButton` for that `SwipeAction`. 



### Expansion



Four built-in expansion styles are provided by `SwipeExpansionStyle`:  



* .selection

* .destructive (like Mail.app)

* .destructiveAfterFill (like Mailbox/Tweetbot)

* .fill



Much effort has gone into making `SwipeExpansionStyle` extremely customizable. If these built-in styles do not meet your needs, see [Customizing Expansion](https://github.com/SwipeCellKit/SwipeCellKit/blob/develop/Guides/Advanced.md) for more details on creating custom styles.



The built-in `.fill` expansion style requires manual action fulfillment. This means your action handler must call `SwipeAction.fulfill(style:)` at some point during or after invocation to resolve the fill expansion. The supplied `ExpansionFulfillmentStyle` allows you to delete or reset the cell at some later point (possibly after further user interaction).



The built-in `.destructive`, and `.destructiveAfterFill` expansion styles are configured to automatically perform row deletion when the action handler is invoked (automatic fulfillment).  Your deletion behavior may require coordination with other row animations (eg. inside `beginUpdates` and `endUpdates`). In this case, you can easily create a custom `SwipeExpansionStyle` which requires manual fulfillment to trigger deletion:



````swift

var options = SwipeTableOptions()

options.expansionStyle = .destructive(automaticallyDelete: false)

````



> **NOTE**: You must call `SwipeAction.fulfill(with style:)` at some point while/after your action handler is invoked to trigger deletion. Do not call `deleteRows` directly.



````swift

let delete = SwipeAction(style: .destructive, title: nil) { action, indexPath in

    // Update model

    self.emails.remove(at: indexPath.row)

    action.fulfill(with: .delete)

}

````
