Choose Slider

Choose slider with value completion

Slider(value:binaryPoint)

swift

binaryPoint is just number, we will bind double 10 to a value

struct ContentView: View {
    
     @State var sliderValue: Double = 10 
    
    var body: some View {
         Slider(value:$sliderValue) 
            .padding(.horizontal)
    }
}

swift

Change the colour

by using .tint()

Add a value in certain number section

.Slider(value: $sliderValue, in: 0...20)

Add a step (몇씩 움직이는지)

.Slider(value: $sliderValue, in: 0...20, step: 1.0)

Format the number

instead of showing 0.0000001 value, we can format the number to show how many decimal points we want to show.

.Text(String(format: "%.2f", sliderValue)

Change color when it gets slided

1. Add a colour variable = .red

2. onEditingCHange: { (_) in color = .green }

3. add min and max value label to show the number

struct ContentView: View {
    
    @State var sliderValue: Double = 5
    @State var color: Color = .red
    
    var body: some View {
        VStack {
            Text("Rating:")
            Text(
                String(format: "%.0f", sliderValue)
            ).foregroundColor(color)
                .font(.title)
            Slider(
                value: $sliderValue,
                in: 1...5,
                step: 1.0,
                onEditingChanged: { (_) in
                    color = .green
                    
                },
                minimumValueLabel: Text("1"),
                maximumValueLabel: Text("5"), label: {Text("Title")})
            
        }.padding(.horizontal)
    }
}

Today, I explored Slider and TabView. While I had previously relied on NavigationStack for view composition, TabView simplifies navigation between different pages.

Slider provides a user-friendly way to select from a range of values. It allows for number formatting, setting of step and range, and labeling of minimum and maximum values.

By using TabView() and .tabItem, we can embed different views within each .tabItem using tags and bindings. TabView presents two styles. The PageTabView style and the default view.
