Sliders in SwiftUI: A Fun Way to Slide Into Your App 👏🏿

Updated: Mar 25, 2023

Are you tired of tapping on buttons to adjust values in your app? Are you ready for a more interactive experience? Well, look no further! Sliders in SwiftUI are the perfect solution to add some fun to your app and give your users more control over their data.

What are Sliders in SwiftUI?

Sliders are user interface elements that allow users to select a value from a range by sliding a knob along a track. In SwiftUI, sliders are represented by the Slider view, which can be customized to fit your app's style and functionality.

Creating a Basic Slider in SwiftUI

Creating a slider in SwiftUI is as easy as pie! First, you need to import the SwiftUI framework. Then, you can create a slider with a minimum and maximum value, a starting value, and a step value like this:

import SwiftUI

struct MySlider: View {
    @State private var value = 50.0
    var body: some View {
        VStack {
                value: $value,
                in: 0...100,
                step: 1.0
            Text("Value: \(value)")

In this example, the slider has a starting value of 50, a minimum value of 0, a maximum value of 100, and a step value of 1.

The value property is marked with the @State attribute, which means that changes to the value will be tracked and update the UI automatically.

Customizing Your Slider

Now that you have a basic slider, it’s time to make it your own! You can customize the appearance and behavior of your slider in many ways. For example, you can change the color of the slider, add a label, or even make it vertical.

Here’s an example of a customized slider:

    value: $value,
    in: 0...100,
    step: 1.0
.frame(width: 300, height: 50)

In this example, we’ve added a purple background color and a yellow accent color to the slider.

We’ve also rotated the slider by 90 degrees and added a frame and padding to make it look better.

Adding Interactivity to Your Slider

What good is a slider if it doesn’t do anything? In SwiftUI, you can add interactivity to your slider by using the onChanged and onEditingChanged modifiers.

Here’s an example of how to add interactivity to your slider:

    value: $value,
    in: 0...100,
    step: 1.0,
    onEditingChanged: { editing in
        print("Slider is being edited: \(editing)")
    minimumValueLabel: Text("0"),
    maximumValueLabel: Text("100"),
    label: {

In this example, we’ve added a closure to the onEditingChanged modifier that prints a message when the slider is being edited. We've also added minimum and maximum value labels and a label for the slider.


Sliders in SwiftUI are a fun and interactive way to give your users more control over their data. With just a few lines of code, you can create a customized slider that fits your app’s style and functionality. So why not slide into your app today and give your users a better experience?
