SwiftReorder

SwiftReorder is a UITableView extension that lets you add long-press drag-and-drop reordering to any table view. It's robust, lightweight, and fully customizable.

Features

Smooth animations
Automatic edge scrolling
Works with multiple table sections
Customizable shadow, scaling, and transparency effects

Installation

CocoaPods

To integrate SwiftReorder into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'SwiftReorder', '~> 5.0'

Manually

You can integrate SwiftReorder into your project manually by copying the contents of the Source folder into your project.

Usage

Setup

Add the following line to your table view setup.

override func viewDidLoad() {
    // ...
    tableView.reorder.delegate = self
}

Add this code to the beginning of your tableView(_:cellForRowAt:).

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    if let spacer = tableView.reorder.spacerCell(for: indexPath) {
        return spacer
    }
    // ...
}

Implement the tableView(_:reorderRowAt:to:) delegate method, and others as necessary.

extension MyViewController: TableViewReorderDelegate {
    func tableView(_ tableView: UITableView, reorderRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {
        // Update data model
    }
}

This method is analogous to the UITableViewDataSource method tableView(_:moveRowAt:to:). However, it may be called multiple times in the course of one drag-and-drop action.

Customization

SwiftReorder exposes several properties for adjusting the style of the reordering effect. For example, you can add a scaling effect to the selected cell:

tableView.reorder.cellScale = 1.05

Or adjust the shadow:

tableView.reorder.shadowOpacity = 0.5
tableView.reorder.shadowRadius = 20
