Remove Row From Section - swift

Question

This is my sectionArray
var sectionArray = [Sections]()
This is how I figure out how many rows in section
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return sectionArray[section].items.count
}
and this is my code to remove a row by sliding.
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == UITableViewCell.EditingStyle.delete {
sectionArray[indexPath.section].remove(at: indexPath.row)
if sectionArray[indexPath.section].title.count == 0 {
sectionArray.remove(at: indexPath.row)
}
tableView.deleteRows(at: [indexPath], with: UITableView.RowAnimation.automatic)
}
}
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let delete = UITableViewRowAction(style: .normal, title: "Delete") { action, index in
//self.isEditing = false
print("delete button tapped")
}
delete.backgroundColor = UIColor.red
return [delete]
}
Theoretically this delete stuff should work but I am getting error No exact matches in call to subscript at
sectionArray[indexPath.section].remove(at: indexPath.row)

Answer 1

/// This line
sectionArray.remove(at: indexPath.row)
/// should be like this
sectionArray.remove(at: indexPath.section)
/// This line will remove the section from the table
tableView.deleteSections(.init(integer: indexPath.section), with: .automatic)
You are using row to remove a section
Edit
Replace all the code you provided us with this
/*
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == UITableViewCell.EditingStyle.delete {
sectionArray[indexPath.section].remove(at: indexPath.row)
if sectionArray[indexPath.section].title.count == 0 {
sectionArray.remove(at: indexPath.row)
}
tableView.deleteRows(at: [indexPath], with: UITableView.RowAnimation.automatic)
}
}
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let delete = UITableViewRowAction(style: .normal, title: "Delete") { action, index in
//self.isEditing = false
print("delete button tapped")
}
delete.backgroundColor = UIColor.red
return [delete]
}
*/
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let delete = UITableViewRowAction(style: .normal, title: "Delete") { action, index in
//self.isEditing = false
sectionArray[indexPath.section].remove(at: indexPath.row)
tableView.deleteRows(at: [indexPath], with: UITableView.RowAnimation.automatic)
if sectionArray[indexPath.section].items.isEmpty {
sectionArray.remove(at: indexPath.section)
tableView.deleteSections(.init(integer: indexPath.section), with: .automatic)
}
}
delete.backgroundColor = UIColor.red
return [delete]
}
