the code:

class moveStruct: ObservableObject {
    var moveIndex: Int
    var moveTitle: String
    var movePlayer: String
    var moveColor: Color

    init(moveIndex: Int, moveTitle: String, movePlayer: String, moveColor: Color) {
        self.moveIndex = moveIndex
        self.moveTitle = moveTitle
        self.movePlayer = movePlayer
        self.moveColor = moveColor
    }
}

struct ContentView: View {
    @State var theCounter: Int = 0
    @State var theMoveArray = [moveStruct]()
    @State var theArrayCounter = 0

  var body: some View {
        HStack {
            var theMove = moveStruct(moveIndex: 0, moveTitle: "S", movePlayer: "Blue", moveColor: .blue)
            var theMove2 = moveStruct(moveIndex: 1, moveTitle: "O", movePlayer: "Red", moveColor: .red)

      Button {
                theMoveArray.append(theMove)
                theMoveArray.append(theMove2)
                theCounter = 0
                var theArrayBounds = theMoveArray.count - 1

        \\print1
                print("pre-timer count: \(theMoveArray.count)")

                Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { timer in

          \\print2
                    print("in-timer count: \(theMoveArray.count)")

                    if theCounter <= (theArrayBounds) {
            print("Timer fired!")
          } else {
                        timer.invalidate()
                    }

                    theCounter += 1
                }
                print("Post-timer count: \(theMoveArray.count)")
                theMoveArray.removeAll()
       } label: {
                Text("The Button")
                    .frame(width: 100, height: 100)
            }
     }
    }
}

When I run this, outside of the timer, theMoveArray.count is 2 as expected. Inside the timer, it's 0. No idea why, but that's the problem.

Someone on StackOverflow said use @StateObject, but I'm not good with a lot of this, and when i try to init an array of moveStruct classes as an empty array:

@StateObject var theMoveArray = [moveStruct]() I get fussed at about "Generic struct 'StateObject' requires that '[moveStruct]' conform to 'ObservableObject'"

I'm at a loss here, I don't have any idea why this isn't working.

I would suggest selecting all your code and giving your keyboard the ol' ⌃I to clean up your indents. It's kinda hard to see what's going on in that Button's action closure because of all the wonky indentation.
