GenericCells

Creating UITableViewCell and UICollectionViewCell subclasses is so Swift 2 point zero.

Introducing, GenericCells!… Capitalizing on Swift's generics, we can get all the benefits of a custom UITableViewCell or UICollectionViewCell class, without the hassle of a new class for each of them.

Let's show you how to use it.

Create a UIView subclass for the layout you want:

final class MyView: UIView {

    let imageView: UIImageView
    let titleLabel: UILabel
    let subtitleLabel: UILabel
    // And add more views to your heart's content

}

Register the cell with a UITableView or UICollectionView:

tableView.register(GenericTableCell<MyView>.self)

collectionView.register(GenericCollectionCell<MyView>.self)

Dequeue the cell with a UITableView or UICollectionView:

let cell = tableView.dequeueReusableCell(forIndexPath: indexPath) as GenericTableCell<MyView>

let cell = collectionView.dequeueReusableCell(forIndexPath: indexPath) as GenericCollectionCell<MyView>

And customize it to your heart's content. The view you wish to access will be available via the .customView property:

cell.customView.titleLabel.text = "This library rules!"
cell.customView.imageView.image = UIImage(named: "success")

Extra credit, let's add recycling support. Extend your view with the ReusableGenericView protocol:

extension MyView: ReusableGenericView {

    func prepareForReuse() {
        self.titleLabel.text = ""
        self.subtitleLabel.text = ""
        self.imageView.image = nil
    }

}

And it will get called when the cell is recycled.

Installation

You can use SPM to install GenericCells.

You can also use CocoaPods to install GenericCells by adding it to your Podfile:

platform :ios, '9.0'
use_frameworks!

pod 'GenericCells'

Or install it manually by downloading GenericTableCell.swift, GenericCollectionCell.swift, and ReusableView.swift, and dropping it in your project.
