I am having an issue when using a slider on WatchOS, that if the value between the max and min is too high, the animation breaks if the step is set to low.

Slider(value: $amountToAdd, in: -1500...1500, step: 10)

These seems odd since if you remove the step, its capable of going through the equivalent of 1 step with no issue.

Slider(value: $amountToAdd, in: -1500...1500)

Is there a way around this limitation, or is this a bug in swiftui with the slider? I do not see anything in the documentation that there is a limit.

I'm not sure about WatchOS and the issue, however you could do this work around

struct ContentView: View {
    @State private var addAmount = 0.0

    var addedAmount: Int {
        Int(addAmount) * 10
    }

    var body: some View {
        VStack {
            Text("\(addedAmount)")

            Slider(value: $addAmount, in: -150...150)
        }
        .padding()
    }
}
