I am trying to enable Leading and Trailing swipe with Long press tableview cell to drag and drop option using Swift. Here, I am using below code I can able to drag and drop it but can’t able to do long press also can't able to enable leading and trailing swipe at a time. Three things need to enable by default when app launched.
Tableview Delegate
override func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let deleteAction = UIContextualAction(style: .normal, title: "Delete", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
print("OK, marked as Delete")
success(true)
})
deleteAction.backgroundColor = .orange
return UISwipeActionsConfiguration(actions: [deleteAction])
}
override func tableView(_ tableView: UITableView,trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let modifyAction = UIContextualAction(style: .normal, title: "Edit", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
print("Update action ...")
self.showaddMilestone()
success(true)
})
modifyAction.image = UIImage(named: "edit")
modifyAction.backgroundColor = .red
return UISwipeActionsConfiguration(actions: [modifyAction])
}
override func tableView(_ tableView: UITableView, shouldIndentWhileEditingRowAt indexPath: IndexPath) -> Bool {
return false
}
override func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {
let movedObject = self.milestoneTitles[sourceIndexPath.row]
milestoneTitles.remove(at: sourceIndexPath.row)
milestoneTitles.insert(movedObject, at: destinationIndexPath.row)
debugPrint("\(sourceIndexPath.row) => \(destinationIndexPath.row)")
// To check for correctness enable: self.tableView.reloadData()
}
You can do this in following way...
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
#available(iOS 11.0, *)
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
//EDIT
let actionEDIT = UIContextualAction(style: .normal, title: "", handler: { (action,view,completionHandler ) in
//do stuff
completionHandler(true)
})
actionEDIT.image = UIImage(named: "icn_edit")
actionEDIT.backgroundColor = UIColor.UIColorFromHex(hex: "F7F7F7")
//PDF
let actionPDF = UIContextualAction(style: .normal, title: "", handler: { (action,view,completionHandler ) in
//do stuff
completionHandler(true)
})
actionPDF.image = UIImage(named: "icn_pdf")
actionPDF.backgroundColor = UIColor.UIColorFromHex(hex: "F7F7F7")
//SHARE
let actionSHARE = UIContextualAction(style: .normal, title: "", handler: { (action,view,completionHandler ) in
//do stuff
completionHandler(true)
})
actionSHARE.image = UIImage(named: "icn_shareGreen")
actionSHARE.backgroundColor = UIColor.UIColorFromHex(hex: "F7F7F7")
let configuration = UISwipeActionsConfiguration(actions: [actionSHARE,actionPDF,actionEDIT])
return configuration
}
// leftAction Leading
func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let leftAction = UIContextualAction(style: .normal, title: "Edit", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
print("leftAction tapped")
success(true)
})
leftAction.image = UIImage(named: "")
leftAction.backgroundColor = UIColor.red
return UISwipeActionsConfiguration(actions: [leftAction])
}
Here's something that works for me but I'm not sure if it's correct and will always work in future
final class ViewController: UITableViewController {
private let data: [String] = [
"1", "2", "3", "4", "5"
]
override func viewDidLoad() {
super.viewDidLoad()
tableView.dragInteractionEnabled = true

I have a simple table view showing a list of tasks. I want to show two buttons when user swipes on a cell. A delete button to delete the cell and Completed button to store the task in completed array. I am able to implement the delete button but no idea of showing a second button in the table cell. here is the code.
import UIKit
var taskArray = [String]()
var datesArray = [String]()
class ViewController: UIViewController, UITableViewDataSource
{
#IBOutlet weak var taskTableView: UITableView!
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return taskArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "taskCell", for: indexPath)
cell.textLabel?.text = "\(indexPath.row + 1). \(taskArray[indexPath.row])"
cell.detailTextLabel?.text = datesArray[indexPath.row]
return cell
}
override func viewDidLoad()
{
super.viewDidLoad()
taskTableView.dataSource = self
let userDefaults = UserDefaults.standard
if let task = userDefaults.stringArray(forKey: "tasks") , let date = userDefaults.stringArray(forKey: "dates")
{
taskArray = task
datesArray = date
}
print(taskArray)
print(datesArray)
// Do any additional setup after loading the view, typically from a nib.
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
taskTableView.reloadData()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// this method handles row deletion
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath)
{
if editingStyle == .delete
{
// remove the item from the data model
taskArray.remove(at: indexPath.row)
datesArray.remove(at: indexPath.row)
// delete the table view row
tableView.deleteRows(at: [indexPath], with: .fade)
}
}
//function to come back from close button
#IBAction func close(segue: UIStoryboardSegue)
{
}
}
Swift 4.0
You can write below method of tableView to define custom swipe action.
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let delete = UITableViewRowAction(style: .default, title: "Delete") { (action, indexPath) in
}
delete.backgroundColor = UIColor.red
let complete = UITableViewRowAction(style: .default, title: "Completed") { (action, indexPath) in
// Do you complete operation
}
complete.backgroundColor = UIColor.blue
return [delete, complete]
}
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let more = UITableViewRowAction(style: .normal, title: "More") { action, index in
//self.isEditing = false
print("more button tapped")
}
more.backgroundColor = UIColor.lightGray
let favorite = UITableViewRowAction(style: .normal, title: "Favorite") { action, index in
//self.isEditing = false
print("favorite button tapped")
}
favorite.backgroundColor = UIColor.orange
let share = UITableViewRowAction(style: .normal, title: "Share") { action, index in
//self.isEditing = false
print("share button tapped")
}
share.backgroundColor = UIColor.blue
return [share, favorite, more]
}
First make this function return true
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool
{
return true
}
it makes your cell editable , apple provides default deleting and editing options that you can use as like this :
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if(editingStyle == .delete)
{
myArray.remove(at: indexPath.item)
table.deleteRows(at: [indexPath], with: .automatic)
table.reloadData()
}
}
func tableView(_ tableView: UITableView, editingStyleForRowAt indexPath: IndexPath) -> UITableViewCellEditingStyle {
if(studentUser as? String == "Admin")
{
return .delete
}
else
{
return .none
}
}
or you can define your custom ones :
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]?
{
let del = UITableViewRowAction(style: .normal, title: "Delete")
{
(action, index) in
let alert = FCAlertView()
alert.makeAlertTypeCaution()
alert.cornerRadius = 10
alert.delegate = self
alert.animateAlertInFromBottom = true
alert.animateAlertOutToTop = true
alert.bounceAnimations = true
alert.blurBackground = true
alert.dismissOnOutsideTouch = true
alert.showAlert(inView: self,
withTitle: "Title you want ",
withSubtitle: "Subtitle Comes here",
withCustomImage: nil,
withDoneButtonTitle:"OK" ,
andButtons:["Cancel"])
}
let edit = UITableViewRowAction(style: .default, title: "Edit")
{
(action, index) in
self.view.makeToast("Editing Coming soon...")
}
del.backgroundColor = AppColor.myNewRedColor
edit.backgroundColor = .lightGray
return [edit,del]
}
Swift 4.0
Add Delegate & DataSource
tableView.delegate = self
tableView.dataSource = self
Add DataSource func "canEditRowAt indexPath"
//MARK: - UITableViewDataSource
public func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
Add Delegate func "editActionsForRowAt indexPath"
//MARK: - UITableViewDelegate
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let editAction = UITableViewRowAction(style: .default, title: "Edit", handler: { (action, indexPath) in
//Action edit
print("Action Edit...")
})
editAction.backgroundColor = UIColor.gray //Set button color
let deleteAction = UITableViewRowAction(style: .default, title: "Delete", handler: { (action, indexPath) in
//Action delete
print("Action Delete...")
})
return [deleteAction, editAction]
}
I hope this helps.
As par your Requirement i have . created Demo for you.
Here is the Output,
When you press Delete element will be removed from Array and when you press Add Button element will be added to new Array.
Here is the link of Demo,
Tableview Demo with Swipable Add and Delete
Step 1:- Connect your Tableview datasource and delegate in Storyboard.
Step 2:- Write DataSource Methods of TableView.
extension ViewController: UITableViewDelegate, UITableViewDataSource {
func numberOfSections(in tableView: UITableView) -> Int {
return 2
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
if section == 0 {
return "Preloaded Data"
} else {
return "Added Data to New Array"
}
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if section == 0 {
return arrPrelodedData.count
} else {
return arrAddNewData.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "SwipeToDelete", for: indexPath) as? SwipeToDelete else {return UITableViewCell()}
if indexPath.section == 0{
cell.lblCellContent.text = arrPrelodedData[indexPath.row] }
else {
cell.lblCellContent.text = arrAddNewData[indexPath.row]
}
return cell
}
//With this we can edit UITableview ex. Swipe to Delete
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
if indexPath.section == 0 {
return true } else {
return false
}
}
//Select tableview Editing Style (insert and Delete)-> if custom icon than set None
func tableView(_ tableView: UITableView, editingStyleForRowAt indexPath: IndexPath) -> UITableViewCellEditingStyle {
return UITableViewCellEditingStyle.none
}
//Delete Action 1) Create delete Action 2) Remove data with Indexpath 3) fetch data from coredata 4) delete tableview row 4) set delete button background color 5) return deleteAction in arry wether it is single
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
//Destructive Because we want to delete(destroy) the data from tableview
let deleteAction = UITableViewRowAction(style: .destructive, title: "DELETE") { (rowAction, indexpath) in
self.arrPrelodedData.remove(at: indexPath.row)
tableView.deleteRows(at: [indexpath], with: .automatic)
}
let addAction = UITableViewRowAction(style: .normal, title: "ADD 1") { (rowAction, indexpath) in
self.arrAddNewData.append(self.arrPrelodedData[indexPath.row])
tableView.reloadSections(NSIndexSet(index: 1) as IndexSet, with: .none)
// tableView.reloadRows(at: [indexPath], with: .automatic)
}
deleteAction.backgroundColor = #colorLiteral(red: 1, green: 0.1491314173, blue: 0, alpha: 1)
addAction.backgroundColor = #colorLiteral(red: 0.9176470588, green: 0.662745098, blue: 0.2666666667, alpha: 1)
return [deleteAction,addAction]
}
}
I hope this answer will helpful for you.
I am making a CheckList application with a UITableView. I was wondering how to add a swipe to delete a UITableViewCell.
This is my ViewController.swift:
import UIKit
class ViewController: UIViewController, UITextFieldDelegate, UITableViewDelegate, UITableViewDataSource {
var tableView: UITableView!
var textField: UITextField!
var tableViewData:Array<String> = []
// Define Colors
let lightColor: UIColor = UIColor(red: 0.996, green: 0.467, blue: 0.224, alpha: 1)
let medColor: UIColor = UIColor(red: 0.973, green: 0.388, blue: 0.173, alpha: 1)
let darkColor: UIColor = UIColor(red: 0.800, green: 0.263, blue: 0.106, alpha: 1)
let greenColor: UIColor = UIColor(red: 0.251, green: 0.831, blue: 0.494, alpha: 1)
init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
// Custom initialization
}
override func viewDidLoad() {
super.viewDidLoad()
//Set up table view
self.tableView = UITableView(frame: CGRectMake(0, 100, self.view.bounds.size.width, self.view.bounds.size.height-100), style: UITableViewStyle.Plain)
self.tableView.registerClass(MyTableViewCell.self, forCellReuseIdentifier: "myCell")
self.tableView.backgroundColor = darkColor
//self.tableView.separatorStyle = UITableViewCellSeparatorStyle.None
self.tableView.delegate = self
self.tableView.dataSource = self
self.view.addSubview(self.tableView)
//Set up text field
self.textField = UITextField(frame: CGRectMake(0, 0, self.view.bounds.size.width, 100))
self.textField.backgroundColor = lightColor
self.textField.font = UIFont(name: "AvenirNext-Bold", size: 26)
self.textField.delegate = self
self.view.addSubview(self.textField)
}
//Table View Delegate
func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int {
return tableViewData.count
}
func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {
var myNewCell: MyTableViewCell = tableView.dequeueReusableCellWithIdentifier("myCell", forIndexPath: indexPath) as MyTableViewCell
myNewCell.text = self.tableViewData[indexPath.row]
return myNewCell
}
func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
let mySelectedCell:UITableViewCell = tableView.cellForRowAtIndexPath(indexPath)
//Colors
mySelectedCell.detailTextLabel.textColor = UIColor.whiteColor()
mySelectedCell.tintColor = UIColor.whiteColor()
//Setup Details / Date
let myDate:NSDate = NSDate()
var myDateFormatter:NSDateFormatter = NSDateFormatter()
myDateFormatter.dateStyle = NSDateFormatterStyle.MediumStyle
mySelectedCell.detailTextLabel.text = myDateFormatter.stringFromDate(myDate)
mySelectedCell.accessoryType = UITableViewCellAccessoryType.Checkmark
mySelectedCell.backgroundColor = greenColor
}
override func prefersStatusBarHidden() -> Bool {
return true
}
//Text Field Delegate
func textFieldShouldReturn(textField: UITextField!) -> Bool {
tableViewData.append(textField.text)
textField.text = ""
self.tableView.reloadData()
textField.resignFirstResponder()
return true
}
}
And this is MyTableViewCell.swift:
import UIKit
class MyTableViewCell: UITableViewCell {
let medColor: UIColor = UIColor(red: 0.973, green: 0.388, blue: 0.173, alpha: 1)
init(style: UITableViewCellStyle, reuseIdentifier: String) {
super.init(style: UITableViewCellStyle.Subtitle, reuseIdentifier: reuseIdentifier)
self.textColor = UIColor.whiteColor()
self.backgroundColor = medColor
self.selectionStyle = UITableViewCellSelectionStyle.None
}
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
I am using iOS8 as deployment target (not sure of the difference it will make).
Add these two functions:
func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
return true
}
func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
if (editingStyle == UITableViewCellEditingStyle.Delete) {
// handle delete (by removing the data from your array and updating the tableview)
}
}
Swift 3.0:
override func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if (editingStyle == UITableViewCellEditingStyle.delete) {
// handle delete (by removing the data from your array and updating the tableview)
}
}
Swift 4.2
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
if (editingStyle == .delete) {
// handle delete (by removing the data from your array and updating the tableview)
}
}
You can try this:
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
if (editingStyle == .delete) {
NamesTable.beginUpdates()
Names.removeAtIndex(indexPath.row)
NamesTable.deleteRowsAtIndexPaths([indexPath], withRowAnimation: nil)
NamesTable.endUpdates()
}
}
If you're supporting iOS11+ please see the discussion:
Use the performBatchUpdates(_:completion:) method instead of this one whenever possible.
Another way that allows you to change the text of "Delete" and add more buttons when sliding a cell is to use editActionsForRowAtIndexPath.
func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
return true
}
func tableView(tableView: (UITableView!), commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: (NSIndexPath!)) {
}
func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {
var deleteAction = UITableViewRowAction(style: .Default, title: "Delete") {action in
//handle delete
}
var editAction = UITableViewRowAction(style: .Normal, title: "Edit") {action in
//handle edit
}
return [deleteAction, editAction]
}
canEditRowAtIndexPath and commitEditingStyle are still required, but you can leave commitEditingStyle empty since deletion is handled in editActionsForRowAtIndexPath.
It's new feature in iOS11 and Swift 4.

if let tv=tableView
{
items.removeAtIndex(indexPath!.row)
tv.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
}
}
}
}
use it :
func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
if editingStyle == UITableViewCellEditingStyle.Delete {
langData.removeAtIndex(indexPath.row) //langData is array from i delete values
tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Automatic)
}
}
hope it helps you
I used tableViewCell to show multiple data, after swipe () right to left on a cell it will show two buttons Approve And reject, there are two methods, the first one is ApproveFunc which takes one argument, and the another one is RejectFunc which also takes one argument.
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let Approve = UITableViewRowAction(style: .normal, title: "Approve") { action, index in
self.ApproveFunc(indexPath: indexPath)
}
Approve.backgroundColor = .green
let Reject = UITableViewRowAction(style: .normal, title: "Reject") { action, index in
self.rejectFunc(indexPath: indexPath)
}
Reject.backgroundColor = .red
return [Reject, Approve]
}
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func ApproveFunc(indexPath: IndexPath) {
print(indexPath.row)
}
func rejectFunc(indexPath: IndexPath) {
print(indexPath.row)
}
Swift 4 -- #available(iOS 11.0, *)

As of Xcode 6.1.1, there are some tiny changes to Dash's answer.
override func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
return true
}
override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
if (editingStyle == UITableViewCellEditingStyle.Delete) {
// handle delete (by removing the data from your array and updating the tableview)
}
}
Swift 3:
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if (editingStyle == UITableViewCellEditingStyle.delete) {
// delete data and row
dataList.remove(at: indexPath.row)
tableView.deleteRows(at: [indexPath], with: .fade)
}
}
Swift 3 with custom title supported
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
//If you want to change title
func tableView(_ tableView: UITableView, titleForDeleteConfirmationButtonForRowAt indexPath: IndexPath) -> String? {
return "Cancel"
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if (editingStyle == UITableViewCellEditingStyle.delete) {
// you might want to delete the item at the array first before calling this function
tableView.deleteRows(at: indexPath, with: .automatic)
}
}
Works for me in Swift 2.0
override func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
return true
}
override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
}
override func tableView(tableView: UITableView,
editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
let block = UITableViewRowAction(style: .Normal, title: "Block") { action, index in
print("Block")
self.removeObjectAtIndexPath(indexPath, animated: true)
}
let delete = UITableViewRowAction(style: .Default, title: "Delete") { action, index in
print("Delete")
self.removeObjectAtIndexPath(indexPath, animated: true)
}
return [delete, block]
}
func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]?
{
let delete = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "DELETE"){(UITableViewRowAction,NSIndexPath) -> Void in
print("What u want while Pressed delete")
}
let edit = UITableViewRowAction(style: UITableViewRowActionStyle.Normal, title: "EDIT"){(UITableViewRowAction,NSIndexPath) -> Void in
print("What u want while Pressed Edit")
}
edit.backgroundColor = UIColor.blackColor()
return [delete,edit]
}
In Swift 4 tableview add, swipe to delete UITableViewCell
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let delete = UITableViewRowAction(style: .destructive, title: "delete") { (action, indexPath) in
// delete item at indexPath
}
return [delete]
}
Swift 5
Since UITableViewRowAction was deprecated in iOS 13.0 so you can use UISwipeActionsConfiguration
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let deleteAction = UIContextualAction(style: .destructive, title: "Delete") { (contextualAction, view, boolValue) in
self.deleteData(at: indexPath)
}
let editAction = UIContextualAction(style: .normal, title: "Edit") { (contextualAction, view, boolValue) in
self.editData(at: indexPath)
}
editAction.backgroundColor = .purple
let swipeActions = UISwipeActionsConfiguration(actions: [deleteAction,editAction])
return swipeActions
}
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func deleteData(at indexPath: IndexPath) {
print(indexPath.row)
}
func editData(at indexPath: IndexPath) {
print(indexPath.row)
}
Swift 4
#available(iOS 11.0, *)
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let action = UIContextualAction(style: .normal, title: "", handler: { (action,view,completionHandler ) in
//do stuff
completionHandler(true)
let data:NSDictionary = self.conversations[indexPath.row] as! NSDictionary
print(data)
let alert:UIAlertController = UIAlertController(title: "", message: "are you sure want to delete ?", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "CANCEL", style: UIAlertActionStyle.cancel, handler: { (action) in
}))
self.present(alert, animated: true, completion: nil)

Simply add method:
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let delete = UITableViewRowAction(style: UITableViewRowActionStyle.destructive, title: "Delete") { (action, indexPath) in
self.arrayFruit.remove(at: indexPath.row)
self.tblList.reloadData()
}
let edit = UITableViewRowAction(style: UITableViewRowActionStyle.normal, title: "Edit") { (action, indexpath) in
let alert = UIAlertController(title: "FruitApp", message: "Enter Fuit Name", preferredStyle: UIAlertControllerStyle.alert)
alert.addTextField(configurationHandler: { (textField) in
textField.placeholder = "Enter new fruit name"
})
alert.addAction(UIAlertAction(title: "Update", style: UIAlertActionStyle.default, handler: { [weak alert](_) in
let textField = alert?.textFields![0]
self.arrayFruit[indexPath.row] = (textField?.text!)!
self.tblList.reloadData()
}))
self.present(alert, animated: true, completion: nil)
}
edit.backgroundColor = UIColor.blue
return [delete,edit]
}

just add these

Xcode asks for UIContextualAction, here what worked for me for the updated version:
For Trailing Swipe Actions:->
func delete(forRowAtIndexPath indexPath: IndexPath) -> UIContextualAction {
let company = companies[indexPath.row]
let action = UIContextualAction(style: .destructive, title: "Delete") { (action, view, _) in
// Perform Delete Action
}
return action
}
func edit(forRowAtIndexPath indexPath: IndexPath) -> UIContextualAction {
let action = UIContextualAction(style: .normal, title: "Edit") { (action, view, escaping) in
// Perform Edit Action
}
return action
}
override func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let delete = self.delete(forRowAtIndexPath: indexPath)
let edit = self.edit(forRowAtIndexPath: indexPath)
let swipe = UISwipeActionsConfiguration(actions: [delete, edit])
return swipe
}
For Leading Swipe Actions:->
func delete(forRowAtIndexPath indexPath: IndexPath) -> UIContextualAction {
let company = companies[indexPath.row]
let action = UIContextualAction(style: .destructive, title: "Delete") { (action, view, _) in
// Perform Delete Action
}
return action
}
func edit(forRowAtIndexPath indexPath: IndexPath) -> UIContextualAction {
let action = UIContextualAction(style: .normal, title: "Edit") { (action, view, escaping) in
// Perform Edit Action
}
return action
}
override func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let delete = self.delete(forRowAtIndexPath: indexPath)
let edit = self.edit(forRowAtIndexPath: indexPath)
let swipe = UISwipeActionsConfiguration(actions: [delete, edit])
return swipe
}
Return true for canEditRowAt for tableView Delegate:->
override func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
