To long to read? Check out our video introduction to Swift UI!
Introduction
Starting from version 3.40.0, Bitmovin’s Player iOS/tvOS SDK officially supports integrating with SwiftUI and/or Combine projects as a first class citizen. 
SwiftUI and Combine are two powerful frameworks introduced by Apple that simplify and speed up the development process and make your code cleaner and more robust.
Single line SwiftUI integration
We introduced VideoPlayerView to enable single line integration of our SDK into your SwiftUI view hierarchy.
It is the equivalent of PlayerView, but for SwiftUI.
Once you have added our SDK to your iOS or tvOS project using our guide, all you need to do is to create a Player instance and add a single line to your SwiftUI view:
VideoPlayerView(player: player)
Full code snippet
The SwiftUI support enables you to get started within minutes.
struct ContentView: View {
private let player: Player = {
// Create player configuration
let playerConfig = PlayerConfig()
// Set your player license key on the player configuration
playerConfig.key = "<PLAYER_LICENSE_KEY>"
// Create player based on player configuration
return PlayerFactory.create(playerConfig: playerConfig)
}()
private let sourceConfig: SourceConfig = {
// Define needed resources
guard let streamUrl = URL(string: "https://cdn.bitmovin.com/content/art-of-motion/m3u8s/playlist.m3u8"),
let posterUrl = URL(string: "https://cdn.bitmovin.com/content/art-of-motion/poster.jpg") else {
fatalError("Invalid URL")
}
return SourceConfig(url: streamUrl, type: .hls)
}()
var body: some View {
VideoPlayerView(player: player)
.background(Color.black)
.onAppear {
player.load(sourceConfig: sourceConfig)
}
}
}
You can find a fully working application example in our open-source sample project here.
Tip: Our Getting Started guide was already updated to highlight the single line SwiftUI integration, making it easier than ever to get your video content displayed within your application.
Reactive event subscription API using Combine
To enhance the support for modern application development trends, now you can use Apple’s own reactive framework, Combine, for subscribing to events. Using Combine for subscribing to individual or multiple events is simplified and allows the usage of standard Combine operators out-of-the-box. You can cancel an event subscription by releasing the Cancellable instance.
This is as easy as adding a couple of lines to your SwiftUI view:
VideoPlayerView(player: player)
.onReceive(player.events.on(TimeChangedEvent.self)) { event in
// Notified for every time changed event
print("Time changed: \(event.currentTime)s")
}
Or anywhere in your codebase:
player.events
.on(TimeChangedEvent.self)
.sink { timeChangedEvent in
// Notified for every time changed event
print("Time changed: \(event.currentTime)s")
}
.store(in: &cancellables)
Tip: In case your project uses UIKit, you can still leverage the
eventsAPI using Combine to simplify your integration.
This new API allows composition of event listeners in a declarative way, which enables the implementation of complex workflows with a couple lines of code:
Publishers.Merge(
player.events.on(SourceErrorEvent.self).map(\.message)
player.events.on(PlayerErrorEvent.self).map(\.message)
)
.sink { [weak self] errorMessage in
// Notified for every source or player error
print("Error message: \(errorMessage)")
}
.store(in: &cancellables)
The events API is supported on both Player and Source, as well as on PlayerView.
To see all supported ways for subscribing to events, check out our brand new documentation page dedicated to showing how to listen to events, available here.
Summary
We are excited about the integration of SwiftUI and Combine in the Bitmovin Player SDK and look forward to seeing the amazing applications you will create with these new features.
