Generic parameter 'Label' could not be inferred SWIFTUI - swiftui

Question

Can someone tell me why on line 9 I get the error Generic parameter 'Label' could not be inferred
struct PlayerControlsView : View {
#State var playerPaused = true
#State var seekPos = 0.0
let player: AVPlayer
var body: some View {
HStack {
Button(action: {
self.playerPaused.toggle()
if self.playerPaused {
self.player.pause()
}
else {
self.player.play()
}
}) {
Image(systemName: playerPaused ? "play" : "pause")
.padding(.leading, CGFloat(20))
.padding(.trailing, CGFloat(20))
}
Slider(value: $seekPos, from: 0, through: 1, onEditingChanged: { _ in
guard let item = self.player.currentItem else {
return
}
let targetTime = self.seekPos * item.duration.seconds
self.player.seek(to: CMTime(seconds: targetTime, preferredTimescale: 600))
})
.padding(.trailing, CGFloat(20))
}
}
}
And of course how to fix it.

Answer 1

Your Slider init is incorrect. There is no version that has from: and through:. in: [0...1] is the default, though, so you don't need it anyway.
Slider(value: $seekPos, onEditingChanged: { _ in
SwiftUI error messages are generally useless. The way you find the error is to keep commenting out things until it compiles, and then add them back in.
However, what you're doing here isn't going to work. You can't put a AVPlayer inside a View. A View is a struct, and they get created, copied, and destroyed all the time. See How to stream remote audio in iOS 13? (SwiftUI).
