How to initialize a Stepper in SwiftUI

Stepper.swift

import SwiftUI

struct ContentView: View {

    @State private var orderCount = 0
    
    var body: some View {
        VStack {
            // Initializing a Stepper
            Stepper(onIncrement: { self.orderCount += 1 },
                    onDecrement: { self.orderCount -= 1 })
            { Text("Value changed. Order count is now \(orderCount) ") }

            // You can also initialize a new Stepper this way (easier)
            Stepper("Set the order amount", value: $orderCount)
            Text("Your order count is now \(orderCount)")
            
            // Adding a slider is also very easy
            Slider(value: $temperature, in: (0 ... 10))
            .rotationEffect(Angle(degrees: temperature))
            // Rotation effect will rotate the slider, as you change the values.
            // See different types of init 

            Text("Temperature is now \(temperature)")
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
