How to Create Square Shape in SwiftUI

SwiftUI provides an intuitive and powerful framework for designing UI components, and shapes are a fundamental aspect of this. Among these, the square is a basic yet versatile shape used in various design contexts, from buttons and icons to placeholders and tiles.

Let’s look into how to create and manipulate square shapes within SwiftUI.

Create a Basic Square

The simplest way to start with squares in SwiftUI is by using the Rectangle shape and specifying equal width and height.

import SwiftUI

struct ContentView: View {
    var body: some View {
        Rectangle()
            .frame(width: 100, height: 100)
    }
}

This code snippet will produce a perfect square with a 100-point side length. The frame modifier is crucial here; it dictates the dimensions of the shape.

Style the Square

SwiftUI allows you to style shapes extensively with fills, borders, shadows, and more.

Rectangle()
    .fill(Color.blue)
    .frame(width: 150, height: 150)
    .border(Color.red, width: 3)
    .shadow(radius: 10)

In the above example, the square has been given a blue color, a red border, and a shadow for depth. The fill modifier changes the interior color, while border and shadow add a border and shadow, respectively.

Rounded Corners

A square doesn’t have to have sharp corners. With SwiftUI, you can easily round the corners of a square.

Rectangle()
    .fill(.red)
    .cornerRadius(20)
    .frame(width: 200, height: 200)

The cornerRadius modifier softens the corners, transforming the square into a rounded square.

Squares with Images

You can also use squares as a clipping mask for images, creating square-shaped images.

Image("dog")
    .resizable()
    .aspectRatio(contentMode: .fill)
    .frame(width: 150, height: 150)
    .clipShape(Rectangle())

The clipShape modifier clips the image to the shape of the rectangle, resulting in a square image.

The square is a staple in design and SwiftUI makes it extremely easy to integrate into your app’s interface. Whether you’re creating a simple button, designing a grid layout, or using squares as clipping masks, SwiftUI’s tools are both simple and robust enough to achieve your design goals.
