Replace a UIViewController with a SwiftUI View

An easy way to start using SwiftUI is to add some to your existing UIKit apps! Replace a UIViewController with a SwiftUI view in the storyboard, and manage data flow between SwiftUI and the rest of the app.

Embed a SwiftUI View in UIKit

You don't have to replace entire view controllers to get started with SwiftUI. You can embed SwiftUI views right into your view hierarchy from the storyboard with the help of @IBSegueAction.

Host a UIKit View in SwiftUI

If UIKit has a view or control that you need in your SwiftUI app, you can integrate it with UIViewRepresentable.

Use a PHPickerViewController in SwiftUI

SwiftUI doesn't have a native photo picker, so you'll need UIKit's help to pick photos from your app. Learn how to use the new PHPicker in your SwiftUI apps.

Implement a UIKit Delegate with a Coordinator

SwiftUI doesn't make much use of the delegate pattern, but it's required for many UIKit controls like the PHPicker. Use a coordinator to add the delegates you need to host UIKit views.

Use Target Action with a Coordinator

The coordinator can help you out with more than delegates! You can also use it to implement target action for UIKit controls in SwiftUI.

This course finishes up our iOS User Interfaces with UIKit learning path, and is for developers with some experience building iOS apps with UIKit and SwiftUI, as you'll be using both in every episode.
