SwidtUI iOS - Cannot use instance member x within property initializer; property initializers run be-CodePudding

struct LePlay: View {

    var fileName: String
    
    init(fileName: String) {
        self.fileName = fileName
    }
    
    @State var player = AVPlayer(url: URL(string: "https://blala.com/?n="   fileName)!)

I get

Cannot use instance member 'fileName' within property initializer; property initializers run before 'self' is available

in the last fileName in the code

I've already seen similar questions but none of the solutions there are working for me

CodePudding user response：

You need to initialise player in your init, as follows:

struct LePlay: View {
    
    var fileName: String
    @State var player: AVPlayer

    init(fileName: String) {
        self.fileName = fileName
        _player = State(wrappedValue: AVPlayer(url: URL(string: "https://blala.com/?n="   fileName)!))
    }
}

I'm not sure what will happen here, assigning a class to State.

You should wrap player in an ObservableObject class, which you can assign to a StateObject
