[Solved] Where to place code for audio playback in a SwiftUI app [closed]

by


Correct, the View shouldn’t take care of data. And SwiftUI enforces this logic.

You could create a Player class which takes care of playing the audio. And add it as an EnvironmentObject, so you can control it with your button in the View. You can then do sweet things like binding your play button to show different images depending on whether the player is… playing 🙂

Update
Code has been updated for Xcode 11 beta 4 (willChange instead of didChange)

struct PlayerView : View {
    @EnvironmentObject private var player: Player

    var body: some View {
        Button(action: {
            self.player.pauseOrPlay()
        }) {
            Image(systemName: player.isPlaying ? "pause.circle.fill" : "play.circle.fill").font(.title).frame(minWidth: 44, minHeight: 44)
        }
    }
}

class Player: BindableObject {
    let willChange = PassthroughSubject<Player, Never>()

    var isPlaying: Bool = false {
        willSet {
            willChange.send(self)
        }
    }

    func pauseOrPlay() {
        // Code that toggles the audio on and off
    }
}
