Requirements

• Xcode 13+
• iOS 11.0+ / tvOS 11.0+ / macCatalyst 13.0+
• Swift 5.3+

If you need Xcode 11 support or Swift 4…Swift 5.2, or iOS 8…iOS 10 support, you can use 7.x releases.

Installation

Swift Package Manager

Add package into Xcode Project settings -> Swift Packages

CocoaPods:

pod 'DTTableViewManager', '~> 11.0.0'

Quick start

Let’s say you have an array of Posts you want to display in UITableView. To quickly show them using DTTableViewManager, here’s what you need to do:

1. Create UITableViewCell subclass, let’s say PostCell and adopt ModelTransfer protocol:

class PostCell : UITableViewCell, ModelTransfer {
    func update(with model: Post) {
        // Fill your cell with actual data
    }
}

2. In your view controller:

class PostsViewController: UITableViewController, DTTableViewManageable {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Register PostCell to be used with this controller's table view
        manager.register(PostCell.self)

        // Populate datasource
        manager.memoryStorage.setItems(posts)
    }
}    

Make sure your UITableView outlet is wired to your class (or use UITableViewController subclass). If you have a PostCell.xib file, it will be automatically used for dequeueing PostCell.

3. That’s it! It’s that easy!

Of course, cool stuff does not stop there, framework supports all datasource and delegate methods as closures, conditional mappings and much much more! Choose what interests you in the next section of readme.

Burning questions

Starter pack

• Why do I need this library?
• How data models are mapped to cells?
• Can I show SwiftUI views in UITableViewCells?
• Can I use unsubclassed UITableViewCell or UITableViewHeaderFooterView?
• How can I register views to dequeue from code/xib/storyboard?
• How can I use the same cells differently in different places?
• What datasource options do I have?(e.g. memory/CoreData/Realm/diffable datasources)
• How can I implement datasource/delegate methods from UITableView?

Advanced

• SwiftUI-backed cells
• Can I implement delegate methods instead of using DTTableViewManager event closures?
• How can I react to and customize UITableView updates?
• What can be additionally configured when using DTTableViewManager with UITableView?
• What if something goes wrong?
